UV Polymer Curing

UV Polymer curing is a process that uses UV light to alter the properties of a polymer, or photopolymer.  A photopolymer is the term for a polymer that responds to UV light, which is basically invisible electromagnetic radiation.  When a photopolymer, which can be a variety of resins, is exposed to the UV radiation, it will typically harden and seal, creating a strengthened surface or an unbreakable bond.

UV Polymer Curing Applications

UV Polymer curing is used in many industrial applications to instantly dry ink or to create a hardened surface without use of solvents or chemicals.  Some common examples of useful applications include:

• Adhesive Bonding

• Inks / Varnishes / Lacquers

• Decorative Glazes

• Coatings

• Label Printing

• Graphic Designs

• Disinfection of Medical Equipment

These are just a few of the many industries that are using UV lamps for curing various polymers.  There are many additional applications for UV curing, and more and more businesses are seeing the benefit of this process.  UV curing was first introduced in the 1960’s, and it is increasingly being adopted by companies as there are many advantages over prior methods of curing polymers.

Curing Lamps

There are three types of UV lamps used for UV polymer curing.  High Pressure UV (HPUV), Medium Pressure UV (MPUV), and Amalgam Lamps.  High Pressure (HPUV) curing lamps are also referred to as Metal Halide lamps, and use mercury with short wavelength outputs.  The HPUV lamps are typically used for the altering of polymers by hardening resins in many of the applications mentioned above.  Medium Pressure lamps (MPUV) are often used for water and air disinfection purposes, while Low Pressure Amalgam lamps are typically used for curing catatonic inks which are inks that are typically an epoxy based resin and respond to UV lighting.  LightSources and our European partner, LightTech, are proud to have pioneered new pellet technology for amalgam lamps.

There are so many benefits to using UV lights for curing it will be difficult to list them all.  We can begin with efficiency.  Imagine a conveyor belt full of parts passing under a UV light as they head to their next destination, possibly quality inspection or packaging.  While no one touched the parts, sprayed solvents on them, or even laid eyes upon them, they underwent a very important process.  Just by passing under the lights, the surface was hardened and strengthened, a strong scratch-resistance texture was enhanced, and any printing or graphic design needing reinforcement was just instantly dried and strengthened.

Now imagine a different manufacturer that does not use UV curing.  They must have an assembly line with people spraying solvents on the parts, requiring face masks and ventilation and still exposing the employees to harmful chemicals in the air and on the skin.  This also opens the door for human error, uneven coating, and inconsistency.

As you can clearly see from these two examples, the efficiency of UV curing is definitely one of the most valuable benefits.  This efficiency also leads to increased production speeds as several parts can be treated at once simply by passing under a row of the proper high intensity UV lighting.   Choosing to cure your parts with UV lighting will increase your output dramatically, while not requiring an investment in an increased labor force, workstation for an added process, or supplies of chemicals that are most likely harmful to the environment.

In addition to efficiency and cost savings, consistency is another big advantage of using UV curing over any other process.  With UV lighting, the amount of exposure is constant, and consistent.  There is no chance of human error in applying an outer coating unevenly on a large amount of parts.  This consistent process results in less quality issues such as internal rejects and the worst rejects of all, customer returns and complaints.   A consistent process is something that all quality minded OEM’s are searching for as consistency results in superior quality, time and again.

Efficiency and consistency are and should always be a top consideration for any production process, (both result in increased profits), but let’s not forget an even more important benefit – the health and safety of your workers and the environment.  Simply by using UV radiation to cure your parts, you are saving your employees from inhaling harmful chemicals, you are not emitting pollutants into the air, and you also do not have to worry about properly storing or disposing of such harmful chemicals.   Any chemical substance on a worksite must be handled with proper storage and disposal guidelines, while maintaining material safety data sheets on the chemical or solvent.

Not only does the increased efficiency and consistency provide an instant return on your investment and a quick increase to the bottom line, not purchasing, storing, disposing of or documenting alternative substances is also a huge savings, and instant increase in profitability.

With all of these benefits, it is difficult to imagine why a manufacturer would choose an alternative method over UV polymer curing.   Efficiency, consistency, safety, less regulations, increased profits, and last but not least – longevity.   LightSources UV curing bulbs will retain their energy output up to 90% of their end of life cycle, enhancing and prolonging all other financial benefits.  As we all know, time is money.  Less time spent processing parts, or replacing bulbs, is an immediate increased profit.

UV Drying Lamps Provide Cost Savings Through Efficiency

UV Drying Lamps

UV drying lamps (or UV curing lamps) are a very important component of the production process in many industries around the globe. Industrial applications of UV drying lamps include:

Automakers

Automakers use UV drying lamps for curing polymers such as specialty resins, inks and varnishes.  When certain polymers are exposed to UV wavelengths, a photochemical process referred to as cross linking occurs producing a hardened and strengthened finish.  This process is used to create hardened gloss surfaces on visible interior parts, or to strengthen plastic parts used in certain assemblies.

UV curing gives automakers a big time saving advantage, as most products treated with UV radiation are cured and touchable within two minutes of time.  This keeps the assembly line moving, with no bottleneck occurring at a treating station.

The Printing Industry 

UV curing of inks is being used instead of solvent based inks in the printing industry, with great benefits.  While solvent inks shrink when drying and evaporate into the air, UV drying lamps provide a consistent clean and crisp finish for various products including glossy postcards, magnets, calendars, and even plastic or wood products.

Packing Companies

Corrugated manufacturers realize the benefit of utilizing UV curing to instantly dry the ink on their packaging products.  This provides a clean crisp vibrant print color, and dries much faster and more consistently than infrared heat drying.  Increased output equals increased profitability.

Flooring

UV light is used to cure concrete, vinyl, and tiles to improve stain resistance and increase the durability of the flooring product.  This process is extremely effective with no toxic odor from chemical treatment, and allows for immediate occupation making it possible to walk on the floor within minutes of treatment.

Other Applications of UV Lighting

UV lamps are also used in various disinfection and purification systems, providing high performance with no use of chemicals. Here are some examples:

UV Disinfection of Medication Equipment

Ultraviolet germicidal treatment of medical equipment includes treating test strips, dialysis machines, syringes, hearing aids, and various other medical devices requiring disinfection.

Air Purification with UV Treatment

Many settings where clean air is critical such as hospitals utilize UV air purification systems to effectively remove harmful contaminants in the air, making it easier to breathe for some people and reducing the likelihood of transmitting bacteria through airborne illnesses.

Water Treatment with UV-Based Solutions

UV Glue Curing

Referred to as liquid glue, UV glue curing is a superior bonding method although this is really a polymer, rather than a glue.  This polymer is often in a silicon glue form, an epoxy, polyurethane, or other polymer that will dry clear only when exposed to UV light.  The UV wavelength is a catalyst for a photochemical reaction which causes the polymer to harden, almost instantly.  In most cases, the polymer will harden when exposed to UV light for only three seconds, although some applications may recommend exposure for ten to fifteen seconds providing optimum bonding adhesion.  This is still considerably less time required for curing polymers than other methods, providing maximum efficiency in several adhesion processes.

UV glue curing is gaining popularity over other methods of bonding such as drying or exposure to chemicals, growing at a rate of 10% per year.  Bonding with heat or drying works by evaporation, which can be inconsistent and can also take time for the inks to dry.  Chemical treatment can be costly to purchase materials, and may expose employees to harmful inhalants or respiratory contaminants.  UV glue curing is quick and consistent, providing and instant hardened surface with no harmful chemical exposure.

UV Glue Curing – A Powerful Photochemical Reaction

Whatever the polymer used, the glue will not harden until exposed to UV light.  This is advantageous over substances such as instant super glues that can stick to fingers or other areas not meant to be bonded together.  With UV polymer or glue curing, the bonding area is targeted, drying instantly only in the area meant to be bonded.  The photochemical reaction occurs when the polymer, or glue, is exposed to UV light at particular wavelengths occurring between 240 Nanometer (nm) and 270 nm and 350nm to 380 nm.

In some cases, a second layer can be applied, providing even more strength for an unbreakable bond.  This UV glue curing process can be used on almost any substrate, bonding plastic, glass, metal and wood, and even glass to glass, or any variation imaginable.  This versatile process can even be applied to three-dimensional parts, saving time and money with quick all over curing.

Where are Curing Lamps Used?

UV curing of glues and polymers is used in a vast number of commercial, industrial and even residential applications.  Some applications that utilize UV glue curing include:

• Decorating of plastic and glass

• Graphic Arts

• Printing

• Electronics

• Automotive

• Boating

• Plumbing

• Manufacturing Processes

Some common examples in commercial applications would be windshield repair or fixing leaking pipes.  Manufacturing processes include assembly lines with parts undergoing UV glue curing in automotive applications such as curing inks on knobs or buttons for interior visual parts.  The gloss provided by the UV process is superior to none, providing clear and shiny print that is resistant to scratching and staining or fading.  The ability to apply this process to three-dimensional parts is advantageous providing speed and efficiency to many manufacturing assembly lines in the automotive and electronics industry.

Endless Options with UV Curing Finishes

One big advantage to the finishes with UV curing is that it dries clear, allowing multiple layers if need be while sanding down the finish will provide an invisible ‘liquid plastic’ unbreakable bond.  Paint or stain can be applied to the finish, giving endless options for applications with various products.

Benefits of UV Glue Curing

The benefits of UV glue curing are evident just from the increased productivity.  The speed at which parts can be cured is a huge benefit, as increased efficiency equals increased profits.  Products speeding by on a conveyor belt undergoing a superior bonding process while on their way to a packing or inspection station is a big time-saver over a lengthy chemical treatment or drying station, thus reducing labor or additional process stations.

Reduced labor is an advantage, along with reduced set up time and reduced clean up time.  A UV polymer curing station would carry a small footprint, not taking nearly as much space as an alternative curing station.  Combined with the high yield enjoyed with this process, the efficiency of UV curing pays with a quick return on investment.

Improved quality is one of the biggest benefits realized with UV glue curing over other methods, as a consistent process equates to improved quality.  With UV curing there is no loss of volume or thickness as with drying methods causing evaporation.  The more consistent UV curing process also means reduced scrap, which is another goal for improved quality.

Stronger parts, with improved scratch resistance and enhanced gloss are also additional benefits with this enhanced curing process.  UV glue curing provides an unbreakable bond, with improved part visual appeal and functionality.   All of this happens with an environmentally friendly process and no harsh chemicals.

Learn How UV Light Curing Improves Your Process

UV light curing is the process of altering the properties of polymers, or photopolymers which refers to polymers that undergo changes to their molecular structure when exposed to light.  UV light emits invisible electromagnetic radiation, causing a change in properties to photopolymers. UV light will cause a photopolymer, which are a wide variety of resins, to instantly dry, harden or seal with an unbreakable bond.

UV light is used in many curing processes worldwide by industrial, commercial and government manufacturing and production companies to improve their process.  By exposing their manufactured polymer products to UV radiation, they can instantly dry ink on parts and strengthen surfaces without using harmful chemicals or solvents.  Some examples of processes that benefit from UV curing include:

• Instantly drying of inks, lacquers and varnishes

• Creating an improved adhesive bond

• Enhancing decorative glazes

• Drying outer surface coatings

• Improving graphic designs

• Screen printing

• Disinfecting of surfaces, air, and water

• Disinfecting medical equipment

This is only a short list of the multitude of benefits realized by UV curing.  As more and more businesses realize the many benefits of curing with UV radiation, there will continue to be an increase in companies adopting this superior curing method in their processes.

Types of UV Light Curing Lamps

The three basic types of lamps used in UV curing processes are:

• Low-Pressure Amalgam Lamps

• Medium-pressure UV (MPUV) Lamps

• High-Pressure UV (HPUV) Lamps

Low pressure amalgam lamps are typically used for polymer curing, although they can also be highly effective in germicidal applications.  Medium Pressure lamps are effective in germicidal applications and are typically used for air, water, and surface disinfection, while high pressure lamps are typically used to alter the properties of photopolymers in many UV curing processes.

Benefits of UV Light Curing

There are a multitude of benefits to using UV lights for curing, some of the most important would be efficiency, consistency and safety.

Efficiency

There is no other method that is quite as efficient at curing products as using UV light.  Depending on your operation, you could utilize specific UV light curing machines for your process or use more of a conveyor type of UV curing station to instantly treat numerous parts, without even touching them.  Imagine the time, money and labor you save by having an instant curing process occurring simply while your parts are being transported from one station to another such as quality inspection or shipping. The alternative methods such as drying or using solvents are less desirable due to several factors.  Force drying or air-drying products leaves them susceptible to inconsistencies with evaporation and possible contamination, and takes more time than an instant UV cure.  In manufacturing, time is money, and anytime you can improve your cycle time with a higher level of quality, it is evident which method is preferred.   UV light curing dramatically improves throughput and cycle times, with less costs than additional labor and purchasing chemicals which could be harmful to employees and the environment.

Consistency

Consistency is key to producing high quality products.   UV curing produces a consistent process with an even amount of UV exposure applied to parts and products, whereas employees applying a chemical spray for an outer coating can produce inconsistencies in the finished product.  Allowing parts to air dry also leaves room for an inconsistent finished surface due to evaporation.  As all quality minded OEM’s are aware, consistency increases the quality of products in all processes.

Safety and Health of Employees

While efficiency and consistency are top considerations for any production process, the safety and health of your workforce is also a top consideration.  With UV curing there is no emission of harmful pollutants and chemicals in the air, and no need to purchase or store hazardous materials and maintain material safety data sheets on such materials.  Using ultraviolet radiation is effective on photopolymers, and safe to the environment and your workforce.  With all these benefits, it is no wonder that OEMs, quality and production managers are realizing the value of ultraviolet radiation to enhance their production processes.  Cost efficient and consistent processes dramatically increase throughput and profitability.  Combined with health and safety practices UV curing is the most desirable of processes used to cure product surfaces.

The power and energy of ultraviolet UV lighting has been used for many years providing valuable uses and applications to a multitude of personal, commercial and industrial uses.  Light is broken down by color, with ultraviolet (UV) light simply meaning “beyond violet”, which is the highest frequency in visible light.  UV light is not visible to the human eye.  UV lighting is a form of electromagnetic radiation emitted at various wavelengths, measured in nanometers (nm).

Ultraviolet Lighting is either UVA, UVB, or UVC

UVA lighting includes the emission of the common blacklight with a range of 315nm to 400nm.  UVB lighting is found in natural sunlight causing a sunburn with wavelengths measuring between 280 to 315nm.  Both UVA and UVB lights are used to enhance many industries such as altering the properties of polymers by causing a photochemical reaction.   Photochemical reactions are used to instantly dry polymers such as inks, varnishes, and polymer resins to provide added strength and durability.

UVC lighting is found in the shorter wavelengths measuring 200 to 280nm and is proven highly effective in disinfection and purification purposes across many commercial and medical industries.  UVB lighting is also very powerful in purifying and disinfecting air and water treatment systems.

As you can see, there are several useful purposes of UV lighting that can enhance the way we manufacture and treat products, clean our air, water and surfaces, and all with environmentally friendly practices.

Types of UV Lighting Lamps  

UV lighting is developed in three basic styles of UV lamps for use in disinfection and curing processes.  The three basic categories of UV lamps are:

• Low Pressure Amalgam Lamps

• Medium Pressure UV Lamps (MPUV) and Medium Pressure High Output (MPHO)

• High Pressure UV (HPUV) Lamps

LightSources is the Leading Manufacturer of all UV Lighting Lamp Styles

LightSources and our European partner, LightTech, are leading global manufacturers of all UV lighting solutions, with many resources including our modern glassworks facility in Hungary.  We continually conduct research and development projects to bring cutting-edge technology to the forefront of the industry in the form of high performing, long-lasting lamps, and lamp products.

LightSources has contributed several patented products with advanced proprietary technology, outperforming the competition of comparable lamp styles and types.  Our UV lamps and lighting solution products are found around the world, providing value to several applications and industries

LightSources Produces High Performing Low-Pressure Amalgam Lamps

Pellet amalgam technology developed by LightSources has several benefits over spot amalgam technology.  LightSources and LightTech lead the industry with patented pellet amalgam lamps.  Our low-pressure pellet amalgam lamps produce higher UV output in dimming conditions than spot amalgam lamps.  With this technology, we are able to provide OEMs the benefit of higher UV output with reduced costs.  Our amalgam lamps produce up to three times more output than comparable lamps of the same size.

Our low-pressure amalgam lamps are useful in curing applications such as instant drying and hardening of inks, varnishes, glazes and resins.  You can also find our LP amalgam technology in germicidal applications such as disinfecting water in various treatment systems, including ships ballast water treatment systems.

Medium Pressure UV (MPUV) and Medium Pressure High Output (MPHO)

Medium pressure UV lamps are useful in the curing process when emitting UVA light in the range of 367 to 400nm, which is the most effective wavelength for curing inks and varnishes.  MPUV lamps are also highly effective in UVC germicidal and microbial disinfection applications.  With vacuum sealed lamps we are a leading producer of UV lighting solutions used in water purification applications, such as water treatment plants and ships ballast water treatment systems.

Medium Pressure High Output (MPHO) lamps are effective in wavelengths ranging from 200 to 400nm, generating high temperatures between 600 and 900° C.  LightSources offers custom solutions with any wattage ranging from 100 watts per inch (WPI) to 700 WPI, and sizes from 2 to 85 inches.

LightSources offers High Pressure UV Lamps (HPUV)

LightSources offers HPUV lamps also referred to as Halide lamps with short wavelength outputs peaking at 254 to 365nm. HPUV lamps emit high output to instantly harden resins and epoxies.  LightSources provides custom HPUV solutions with additives such as Gallium-iodide which can increase the wavelengths to 400nm.

Many industries realize the benefit of HPUV lighting such as automotive, aerospace, food and beverage, medical, water treatment processes and many more.
