Dymax Corporation has released OC-3021, 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. The coating, engineered for superior scratch, abrasion, and chemical resistance, is ideal for use with film substrates such as PET 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-3021 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 percent 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-3021 is formulated to cure with Dymax's broad-spectrum UV light-curing equipment.
