FLEXIBLE SILICONE COATINGS FOR PLASTIC SUBSTRATES AND METHODS FOR MAKING THERMOFORMABLE, ABRASION-RESISTANT THERMOPLASTIC ARTICLES

摘要

An improved silica-containing curable coating composition is described herein. The composition has an alkaline pH and contains a dialkyldialkoxysilane/alkyltrialkoxysilane mixture and a dispersion of ammonium-stabilized colloidal silica having an average particle size no greater than about 5-10 millimicrons. Methods for preparing such compositions are also disclosed, as are thermoplastic articles which include the cured protective coatings.
