Abstract

A flame sprayable powder composition suitable for coating a plastic substrate comprising by weight (a) about 90 to 98% of a flame sprayable mineral powder, (b) about 1 to 5% of a nylon powder, and (c) about 1 to 5% of an epoxy resin powder. The coated plastic may thereafter be overcoated by flame spraying with conventional metal or ceramic powders. The undercoat results in a good bond to the substrate.
