Coating for glass substrate for anti-reflective properties with abrasion, chemical and UV resistance
Patent number: 6352780Abstract: The present invention relates to a polymeric coating composition for application onto glass substrates for anti-reflective properties. The coating is provided via chemical grafting that involves the use of monomers and/or prepolymers, catalyst, and graft initiator and when applied onto the surface of the glass substrate forms a polymeric film chemically bonded to the glass with excellent adhesion. This coating can reduce the reflectance of the coated glass surface to as close to zero as possible, thus maximizing transmittance and providing resistance to abrasion, water/chemical attack, and UV degradation.Type: GrantFiled: February 22, 2000Date of Patent: March 5, 2002Assignee: AFG Industries, Inc.Inventors: Mohan L. Sanduja, Carl Horowitz, Abraham Thomas, Paul Thottathil -
