A primer composition comprising metal oxide particles modified with an alkyltrialkoxy silane; an organic polymer; and a solvent. The weight ratio of alkyltrialkoxy silane to metal particles is at least 0.9:1. The primer compositions produce films having excellent optical and adhesion characteristics.

Primer formulations with improved photostability

Disclosed herein is a primer composition comprising an inorganic UV absorbing agent and a polymer selected from (i) a copolycarbonate, and (ii) a polyurethane obtained by reaction of a polyisocyanate and a copolycarbonate diol. Also disclosed is a coated article comprising a polymeric substrate, a primer layer disposed on at least one surface of said substrate, and an abrasion-resistant layer disposed on said primer layer, where the primer layer is made from the primer composition of the invention.

Weatherable and abrasion resistant coating systems for polymeric substrates

The present invention relates to thermal cure silicone hardcoat compositions that are prepared with an aqueous/organic solvent silicone dispersion, partial organoalkoxysilane condensate and silylating agent. The novel heat curable silicone hardcoats are useful on various substrates with improved flexibility.

Flexible thermal cure silicone hardcoats

An improved method for concentrating solids in silicone resin coating compositions is provided, said compositions comprising higher solids levels that are often needed in order to increase the thickness of the final coated film when applied to a given substrate.
