Patent number: 6538092Abstract: The present invention discloses compositions as well as methods of making and using said compositions, having improved stability which, when applied to a variety of substrates and cured, form transparent coatings having abrasion resistant properties and a matched refractive index to that of the substrate. The compositions comprise an aqueous-organic solvent mixture containing a mixture of hydrolysis products and partial condensates of an epoxy-functional silane, a carboxylic acid functional compound selected from the group consisting of carboxylic acids, multifunctional carboxylic acids, anhydrides, and combinations thereof, a metal oxide composite colloid, a colloidal silica material, and a tetrafunctional silane. The coating compositions of the present invention may further include a mixture of hydrolysis products and partial condensates of one or more silane additives.Type: GrantFiled: April 20, 2000Date of Patent: March 25, 2003Assignee: SDC Coatings, Inc.Inventors: Karl W. Terry, Bryan S. Lembo

Patent number: 5316791Abstract: A process for improving the impact resistance of a coated plastic substrate, particularly those polymers having a high refractive index, comprising applying an aqueous polyurethane dispersion as a primer layer to at least one surface of the plastic substrate, at least partially curing the aqueous polyurethane dispersion by air drying at ambient temperature, applying a coating composition over the polyurethane primer layer, and curing the coating composition to form an abrasion resistant hard coat. Preferably, the aqueous polyurethane dispersion is air dried at ambient temperature for less than one hour before application of the abrasion resistant coating composition. The process provides an impact enhancing, abrasion resistant coating system having strong interfacial adhesion that is preferably transparent for application onto preferably transparent plastic articles, such as ophthalmic lenses and safety eye wear.Type: GrantFiled: January 21, 1993Date of Patent: May 31, 1994Assignee: SDC Coatings Inc.Inventors: Bruce M.
