摘要： A refinish coating system comprising (I) an intermediate coating composition and (II) a topcoat coating composition is useful for repairing a damage area of a silicone hard coat layer on an automotive resin glazing substrate. The intermediate coating composition (I) comprises (A) a reactive siloxane compound and (B) silica. The topcoat coating composition (II) comprises (C) an alkoxysilane having a UV-absorbing functional group, (D) a multifunctional alkoxysilane, (E) a reactive siloxane compound, (F) colloidal silica, and (G) phosphoric acid. The system forms a coating having the same appearance and physical properties as the underlying silicone hard coat layer.

摘要： A plastic substrate for automotive glazing is provided. The substrate is an article comprising first layer in contact with the substrate surface, which is a layer prepared by curing a coating composition containing a vinyl copolymer having an alkoxysilyl group and a UV-absorbing group and a fine particle silicon oxide and not containing any curing catalyst; second layer in contact with the first layer, which is a layer prepared by curing an organopolysiloxane composition containing a curing catalyst and a co-hydrolyzate of an organosilicon compound containing a UV-absorbing organooxysilane and a fine particle silicon oxide; and third layer in contact with the second layer, which is a layer prepared by curing an organopolysiloxane composition containing a curing catalyst having an activity stronger than the catalyst used in the second layer, and a co-hydrolyzate of an organosilicon compound containing a UV-absorbing organooxysilane and a fine particle silicon oxide.
