BESCHICHTETER POLYCARBONAT-GEGENSTAND MIT VERBESSERTER ABRIEB- UND LOESUNGSMITTELBESTAENDIGKEIT UND VERBESSERTER HAFTUNG DER BESCHICHTUNG AUF DEM POLYCARBONAT

摘要

A shaped, non-opaque coated polycarbonate article having improved abrasion and chemical solvent resistance comprising a polycarbonate substrate having disposed on the surface thereof a non-opaque primer layer comprised of from about 25 to about 85 weight percent of a thermoset acrylic polymer and from about 15 to about 75 weight percent of at least one ultraviolet light screening compound, and disposed on said primer layer a non-opaque top coat comprised of a colloidal silica filled thermoset organopolysiloxane.
