description A process for providing a uniform, durable and tenaciously adhered scratch, mar, abrasion and chemical solvent resistant organopolysiloxane coating on a polycarbonate substrate. The process includes(i) applying a priming composition comprising an emulsion of a thermosettable acrylic polymer and a hydroxy ether to a polycarbonate substrate; (ii) curing the thermosettable acrylic polymer thereby forming a thermoset acrylic primer layer on said substrate; (iii) applying a top coat composition containing a further curable organopolysiloxane onto said primed substrate; and (iv) curing said further curable organopolysiloxane.
