PURPOSE:To obtain the titled organic solvent-free paint with no health hazard, applicable in a simple way, for use in rustproof treatment for portions elevated in temperature, of steel plates or steel pipes provided with fusing or welding, by melt blending of a wax of specific melting point and zinc powder in specified proportions. CONSTITUTION:The objective paint comprising (A) a wax of a melting point 60-160 deg.C (e.g., with a weight-average molecular weight 300-40,000, such as paraffin wax) and (B) 50-90wt%, based on the final composition, of zinc powder. This paint does not require any sophisticated painting equipment, etc., being applicable in a simple way, causing no contamination of the environment, capable of making use of energy when repairing or painting the portions still hot after welding or fusing, having no pot life, and can be used with no waste by fusing a new batch to shortened one.
