Title (EN) METHOD FOR COATING A POLYCARBONATE ARTICLE WITH SILICA FILLED ORGANOPOLYSILOXANE
(FR) PROCEDE DE REVETEMENT D"UN ARTICLE DE POLYCARBONATE AVEC UN ORGANOPOLYSILOXANE CHARGE EN SILICE
Abstract: front page image
(EN)A process for providing a durable and tenaciously adhered scratch, mar, abrasion, and chemical solvent resistant colloidal silica filled organopolysiloxane coating on a polycarbonate substrate. The process includes (i) applying a priming composition comprised of an emulsion of a thermosettable acrylic polymer and a hydroxy ether to a polycarbonate substrate; (ii) curing the thermosettable acrylic polymer thereby forming a primer layer on said substrate; (iii) applying onto the primed substrate a top coat composition containing a colloidal silica filled further curable organopolysiloxane; and, (iv) curing the silica filled organopolysiloxane.
(FR)Procede d"obtention une couche de revetement en organopolysiloxane charge en silice sur un substrat de polycarbonate, couche durable et adherente de maniere tenace, resistante aux rayures, a l"abrasion et aux solvants chimiques. Le procede comprend (i) l"application d"une composition d"amorcage, consistant en une emulsion d"un polymere acrylique thermodurcissable et d"un hydroxy ether, sur un substrat de polycarbonate, (ii) la polymerisation du polymere acrylique thermodurcissable, formant ainsi une couche d"amorcage sur le dit substrat, (iii) l"application, sur la surface amorcee, d"une composition de couche superficielle comprenant un organopolysiloxane additionnel charge en silice colloidale, et (iv) la polymerisation de l"organopolysiloxane charge en silice.
