Original Press Release:

Optically Clear Hard Coating Provides Superior Durability and Increased Film Life

Dymax Corporation has released OC-4021, a UV-curable, optically clear hard coating typically used in the manufacture of electronic touch-panels, polarized sunglasses, safety glasses and goggles, and LCD polarized displays.  This coating, engineered for superior scratch, abrasion, and chemical resistance, is ideal for use with film substrates such as PET and TAC, and is especially suitable for printing applications that require printing on top of the hard coating.  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, reducing 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.  This optical coating is formulated to cure with Dymax's broad-spectrum UV light-curing equipment.
