UV Curing Now Possible with Low Pressure Lamp Technology


Ultraviolet (UV) lamps are used worldwide in various applications to cure, bond or instantly dry various materials including inks, resins and adhesives.  When UV waves come into contact with specialty polymers, it causes a photochemical reaction, altering the molecular structure of the polymer.  High-pressure UV lamps have been used for decades to create this chemical reaction, producing the UVA wavelength as the ideal catalyst for the curing function.  In recent years, however, new technology utilizing low-pressure UV lamps with a wavelength of 254 nanometer (nm), has been highly effective in curing various materials.

Low-pressure lamps operate with less energy output required, providing energy savings over heat-based curing system.  UV curing also produces a higher quality product over heat based curing or drying, as the molecular change occurs instantly, in a matter of seconds, preventing evaporation or dust particles to contaminate your product surface.  UV curing systems also produce no hazardous byproducts, and pose no risk of chemical interaction with your employees or other materials.

UV lamps purchased from an experienced Ultraviolet and lighting expert gives you assurances that your lamps are manufactured with the proper wavelength output for your application, and that they will provide a long lasting useful life which saves a considerable amount of money over purchasing and storing chemicals or other drying agents.

Low pressure UV lamps are ideal for applications that require dimming, as compared to medium and high-pressure lamps.  Low pressure mercury lamps along with amalgam lamps are increasingly used for UV curing applications and the effective drying of adhesives that have a cationic base.

UV Glue Curing Creates Unbreakable Bond


Ultraviolet radiation energy is used as a catalyst to instantly cure polymers, creating an instant bond in as quickly as three seconds.  This photochemical reaction is often used on polymers such as silicone glue, polyurethane and epoxies which will instantly cure when exposed to UV light.

UV curing of polymers provides many advantages over other methods such as chemical application and air drying.   UV curing provides the quickest cure time when compared to these other methods, while providing a stronger, unbreakable bond.   When air drying inks, coatings, adhesives and glues, the surface is exposed to outer contaminants in the air which can create an inconsistent surface.  UV curing is also much faster than air drying, drastically improving cycle times and productivity, leading to increased profitability.

When using chemicals to dry surface coatings and bonding agents, it can be costly and time consuming while still not providing the same consistent and quick output as UV curing.   Chemical drying processes can also create an unsafe environment to employees by exposing them to harmful contaminants.  An air controlled evaporation system is often necessary to remove fumes or toxins from chemical use.  UV curing dries so quickly it leaves a consistent and high-quality surface that is reinforced and resistant to scratching or breaking.

UV glue curing provides many benefits over other methods, with precision accuracy to target specific areas.  By projecting the UV light directly towards the area of polymer requiring hardening, manufactures can precisely cure specific areas without affecting surrounding areas.

Unbreakable Polymer Bond with UV Curing

post 95 UV glue curing is becoming a popular method for many commercial and industrial processes requiring a permanent unbreakable bond in their application.   Often referred to as liquid glue, when sealed with the powerful effects of ultraviolet (UV) radiation, it is more often a polymer rather than glue that provides a strengthened bond.   Often times polyurethane, epoxy or other polymer is used and will dry clear when exposed to UV light.

These specialty polymers harden within seconds of exposure to UV radiation, typically within three seconds although some processes may require additional exposure for maximum adhesion.  Regardless of the time in seconds, this process is considerably less time consuming than applying a chemical coating or other drying methods.

Chemical treatment of manufactured parts requires the purchase of toxic chemicals and ventilation areas for employees applying these volatile compounds.  Bonding with drying takes more time than with UV curing and can also leave inconsistencies in your finished product due to evaporation.

UV Glue Curing Provides Fast and Consistent Bonding

UV glue curing is fast and effective, providing instant hardening with no evaporation or chemical exposure.  Ultraviolet radiation provides effective solutions for large volume production with consistently accurate results.

Curing polymers with UV light provides quick cure rates and allows for specific, targeted applications whether applied to glue or any other various polymers.  The most effective wavelength of UV radiation occurs between 240nm – 270nm, or 350nm to 380nm.
