Press Release Summary:

July 1, 2014 - Engineered for resistance to scratches, abrasion, and chemicals, OC-4122 UV-curable, optically clear, hard coating for polycarbonate lenses is suited for use with such film substrates as PC, PET, TAC, and PMMA. Surface energy prevents materials from readily adhering to cured coating, resulting in non-stick or self-cleaning surface, while transparency and low haze characteristics maintain optical clarity over time. This 100% solids hard coating cures tack free when exposed to UV light.

Optically Clear Hard Coating Provides Superior Durability and Increased Film Life

Press release date: June 26, 2014

Dymax Corporation has introduced OC-4122, a UV-curable, optically clear, hard coating for polycarbonate lenses.  The coating, engineered for superior scratch, abrasion, and chemical resistance, is ideal for use with film substrates such as PC, PET, TAC, and PMMA.  Its low surface energy prevents materials from easily adhering to the cured coating, resulting in a non-stick or self-cleaning surface.  OC-4122 is especially suitable for applications where there is a desire to keep the surface free from inks, adhesives, and coatings.  It offers excellent transparency and low haze characteristics, maintaining optical clarity over time for better performance and aesthetics.

This 100% solids hard coating is formulated to lower production, shipping, and life-cycle costs while reducing ecological impact.  It quickly cures tack free when exposed to UV light, enabling faster processing, fewer defects, and greater output.  It also ships with no solvents, resulting in reduced freight costs, but can still be mixed with a variety of solvents just before roll or dip coating to obtain a desired coating thickness of 2 to 5 microns.  OC-4122 is formulated to cure with Dymax's broad-spectrum UV light-curing equipment.
