20080280144 | COATING COMPOSITION YIELDING ABRASION-RESISTANT TINTABLE COATINGS - A coating composition based upon at least partially hydrolyzed epoxy-functional alkoxy silanes and having particular utility in forming tintable, abrasion resistant coatings on lenses. Incorporation in the composition of a non-hydrolyzed epoxy-functional alkoxy silane provides a desired reduction in viscosity. Incorporation in the composition of a polyether surfactant provides a cured coating of the composition with increased tintability. | 11-13-2008 |
20080311408 | Optical Coating Composition - Coating compositions yielding cured coatings that exhibit excellent abrasion-resistance and hardness for use on polymeric substrates such as the front side of optical lenses, in a manner that meets or exceeds the stringent requirements for such use. The compositions include a monomeric organofunctional silane, and colloidal silica present in an amount sufficient to improve abrasion resistance as compared to a composition lacking the colloidal silica. | 12-18-2008 |
20100068539 | OPTICAL COATING COMPOSITION - Coating compositions yielding cured coatings that exhibit excellent abrasion-resistance and hardness for use on polymeric substrates such as the front side of optical lenses, in a manner that meets or exceeds the stringent requirements for such use. The compositions include the hydrolysis product of an epoxy functional alkoxy silane, a viscosity-reducing amount up to 50% by weight, solids basis, of a monomeric (silanol free) epoxy functional epoxy silane, and colloidal silica present in an amount sufficient to improve abrasion resistance as compared to a composition lacking the colloidal silica. | 03-18-2010 |
