Abstract

A heat-resisting coating composition prepared by binding with a mixture of modified silicone resin and an aluminum chelate compound, pulverized inorganic material consisting essentially of a mixture of powder containing at least one member selected from the group consisting of aluminum phosphate, zinc molybdate and calcium carbonate, plate-shaped powder principally containing aluminum silicate or magnesium silicate, and metallic zinc powder. The composition exhibits 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 fine protrusions having "turn-rounds" on the metal surface.
