摘要

A heat-resisting coating composition prepared by binding with modified silicone resin added with an aluminium chelate compound, pulverized inorganic material principally including a mixture of powder containing one kind selected from a group consisting of aluminium phosphate, zinc molybdate and calcium carbonate or a mixture of them, cleaving scale-shaped powder principally containing aluminium silicate or magnesium silicate, and metallic zinc powder; reveals excellent rust-preventing performance in a temperature range spreading from a low temperature to a high temperature, as a heat-resisting painting material for use on an exhaust pipe connected with a motor car engine. Upon applying said heat-resisting coating composition onto a metal surface, it is effective for enhancing adhesion to preliminarily form a group of fine protrusions having "turn-rounds" on the metal surface.
