ABSTRACT:
An anti-nitriding composition comprising a water-based alkyd resin having suspended therein particulate tin and titanium dioxide; a thixotropic agent maintains the particulates in suspension during storage and application; the composition includes surfactant and co-solvent to impart paint-like characteristics. The composition is suitable for use as a local shield during the heat treatment of metals to prevent nitriding or ferritic nitro-carburization at temperatures in the range of about 850.degree. F. to about 1150.degree. F. The water-based formulation is safe to use and to transport, and has an air drying time at normal working temperatures comparable to those drying times previously achievable only with organic-solvent based anti-nitriding compositions.
