Today's business encounters global rivalry, high labor rates, and increased policy associated with air emissions, waste clearance, and safety and health. Therefore for a wood finisher, it is necessary to use less labor intensive finishes that can be applied and dried fast to make possible high-production speeds. They have low impact on the work and natural environment.

The word UV stands for ultra violet. The standard wavelength of UV curing coating is from 200-400 nanometers. These UV Coating are solvent free, and are almost non volatile. They are 100% solid basis. i.e., the complete liquid converts into a solid film. UV coating fabric stays liquid unless exposed to UV light.

"UV coating" means surface treatments which can be cured either by ultraviolet radiation, or by protecting the material from its critical effects. UV Coating is a very polished, lustrous coating applied to the printed paper surface and dried using ultraviolet light. The polished exterior of UV coating makes it striking and accepted for printing covers on paperback novels.

There are numerous benefits associated with Ultraviolet (UV) curable coating. It can offer significant benefits for manufacturers:

• Increased efficiency

• Quick drying time with minimum heat

• Concentrated floor space supplies

• Lower power costs (up to 75 percent)

• Concentrated solvent content and VOC emission

• One-part formulations

• Indefinite pot time

• Environment friendly

• Easily biodegradable

• Easily disposable

• Energy efficient

• More durable

• High production speeds

Application of UV Coating

UV curable coatings has lot of applications in paper and board, graphic arts, c.d, optical fibers, automobile paints, plastic coating, wood coatings, etc. UV curable overprint varnishes are used extensively in the printing and packaging industry. UV curable inks are used in different printing equipment like flexo, offset and letterpress.
