发明名称 WERKWIJZE TER VERVAARDIGING VAN EEN VOORTBRENGSEL VAN POLYCARBONAAT MET EEN UNIFORME EN DUURZAME BEKLEDING DIE EEN ORGANOPOLYSILOXAN EN SILICIUMOXIDE ALS VULSTOF BEVAT.
摘要 <p>A process for providing a protective coating on a polycarbonate substrate comprising (i) applying onto said polycarbonate substrate a priming emulsion composition containing (a) a thermosettable acrylic polymer, (b) an ultraviolet light absorber selected from the benzylidene malonates and cyanoacrylates, (c) water, and (d) a hydroxy ether or an alkanol; (ii) curing the thermosettable acrylic polymer thereby forming a primer layer containing a thermoset acrylic and an ultraviolet light screener on said substrate; (iii) applying a top coat composition containing colloidal silica and a further curable organopolysiloxane; and (iv) curing said further curable organopolysiloxane thereby obtaining a silica filled thermoset organopolysiloxane top coat.</p>
