REPAIR COATING MATERIAL FOR AUTOMOTIVE RESIN GRAZING, AND METHOD FOR REPAIRING AUTOMOTIVE RESIN GRAZING

摘要

PROBLEM TO BE SOLVED: To provide a repair coating material for automotive resin grazing, which is recoated on a silicone hard coat film so that a coating film having the external appearance and physical properties similar to those of a coating film portion of the primarily-coated silicone hard coat film can be formed.SOLUTION: The repair coating material, which is used for repairing a damaged portion of a silicone hard coat layer on an automotive resin grazing base material, comprises an intermediate coating material composition (I) and a top coating material composition (II) to be coated thereon. The intermediate coating material composition (I) contains a reactive siloxane compound (A) and silica (B) and the top coating material composition (II) contains alkoxysilane (C) having an ultraviolet light-absorbable functional group, polyfunctional alkoxysilane (D), another reactive siloxane compound (E), colloidal silica (F) and phosphoric acid (G).
