Can I cure UV glue with a laser?
Yes, if it’s a UV or deep blue laser. It doesn’t matter where the UV photons come from… they just have to kick off the polymerization. Some glues have thermal activation too. So, ask the manufacturer for their particular cure schedule. I’ve used a sweet snap cure system (thermal adhesives) using a microwave source.

That’s why manufacturers have turned to UV curing, a process that allows for the instant “drying” of specialized coatings, inks and adhesives. UV curable inks and coatings were initially created as an alternative to solvent-based products.
What is UV formulation?
UV formulations are liquid monomers and oligomers mixed with a small percentage of photoinitiators which are then exposed to UV energy. In just a few seconds, the formulation hardens or cures and is then ready for the next processing step. Both low- and high-pressure laminates begin as a film and go through this UV curing process.
What happens when a lamp is exposed to a specially formulated ink?
When the light produced by one of these lamps is exposed to a specially-formulated ink or adhesive, it activates a photochemical reaction within that material that causes it to harden in a matter of seconds. The result is a coating that loses no volume or thickness in the process and features superior bonding and resistance over conventionally dried coatings.
How does air drying work?
Conventional heat and air drying work through a process of solvent evaporation, which can wind up shrinking the initial coating application by more than 50 percent. Not to mention, it’s not the most environmentally friendly option.
Can laminates be UV cured?
Both low- and high-pressure laminates begin as a film and go through this UV curing process. Both also allow for B-stage curing, which means that the film can be partially cured by a third party, such as Duracote. The laminates are then provided to you for application to the substrate and the final curing stage.

Cure times are important in processes that require a high degree of accuracy, such as applications within the medical, optical, and electronics industries. Additionally, any component that requires high stability while retaining ...
How to choose UV adhesive?
To choose the right UV adhesive, consider the photoinitiator system in the adhesive: UV-only or UV-plus visible. Then determine transmission characteristics of the substrate. If the substrate transmits visible light but not UV light (that is, is UV opaque), you cannot use a product that contains only a UV photoinitiator; a visible light photoinitiator must be present in the product. If the substrate transmits both UV and visible light, any source will cure a product, although the main concern is speed of cure, which is related to light intensity.

What is UV curing?
UV curing ( ultraviolet curing) is the process by which ultraviolet light is used to initiate a photochemical reaction that generates a crosslinked network of polymers. UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and materials. In comparison to other technologies, curing with UV energy may be considered a low-temperature process, a high-speed process, and is a solventless process, as cure occurs via direct polymerization rather than by evaporation. Originally introduced in the 1960s, this technology has streamlined and increased automation in many industries in the manufacturing sector.
Why is UV curing important?
Because UV energy has unique interactions with many different materials, UV curing allows for the creation of products with characteristics not achievable via other means. This has led to UV curing becoming fundamental in many fields of manufacturing and technology, where changes in strength, hardness, durability, chemical resistance, and many other properties are required.
What is UV LED?
Since development of the aluminium gallium nitride LED in the early 2000s, UV LED technology has seen sustained growth in the UV curing marketplace. Generating energy most efficiently in the 365-405 nm 'UVA' wavelengths, continued technological advances, have allowed for improved electrical efficiency of UV LEDs as well as significant increases in output. Benefiting from lower-temperature operation and the lack of hazardous mercury, UV LEDs have replaced medium-pressure lamps in many applications. Major limitations include difficulties in designing optics for curing on complex three-dimensional objects, and poor efficiency at generating lower-wavelength energy, though development work continues.
What industries use UV ink?
Other industries that take advantage of UV curing include medicine, automobiles, cosmetics (for example artificial fingernails and gel nail polish ), food, science, education, and art. UV curable inks have met the requirements of the publication sector on a variety of papers and boards.
What is UV ink used for?
Printing with UV curable inks provides the ability to print on a very wide variety of substrates such as plastics, paper, canvas, glass, metal, foam boards, tile, films, and many other materials.
Why is ultraviolet light good for curing?
A primary advantage of curing with ultraviolet light is the speed at which a material can be processed. Speeding up the curing or drying step in a process can reduce flaws and errors by decreasing time that an ink or coating spends wet. This can increase the quality of a finished item, and potentially allow for greater consistency. Another benefit to decreasing manufacturing time is that less space needs to be devoted to storing items which can not be used until the drying step is finished.
What is mercury vapor used for?
Low-pressure mercury-vapor lamps generate primarily 254 nm 'UVC' energy, and are most commonly used in disinfection applications . Operated at lower temperatures and with less voltage than medium-pressure lamps, they, like all UV sources, require shielding when operated to prevent excess exposure of skin and eyes.
