Abstract
Disclosed is a method for repairing a damaged area of a silicone hard-coat layer on an automotive resin glazing substrate by applying an intermediate coating composition (I) to the damaged area and applying a topcoat coating composition (II) to the intermediate coating composition. The intermediate coating composition (I) contains (A) a reactive siloxane compound and (B) silica. The topcoat coating composition (II) contains (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 method forms a coating having the same appearance and physical properties as the underlying silicone hard-coat layer.
