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.
