Abstract

An anhydrous liquid composition for phosphatizing metallic surfaces, e.g. of iron, steel, galvanised iron, aluminium, magnesium or alloys thereof, comprises trichlorethylene or perchlorethylene as predominant ingredient; an alcohol containing 3-8 carbon atoms and/or acid alkyl phosphate having at least one alkyl group containing 3-8 carbon atoms, e.g. from 1 to 10% by weight; a solubilized divalent zinc compound, e.g. the phosphates, chloride, fluoride, chlorofluoride, fluorophosphate, carbonate, formate, acetate, naphthenate, oleate, palmitate, stearate, adipate, or alcoholates (corresponding to above alcohols), or alkyl compounds such as dimethyl/diethyl/di-n-butyl/di-isoamyl zinc, e.g. to give from 0.001% to 1% by weight of Zn; and phosphoric acid or a phosphate compound as a phosphatizing agent, e.g. from 0.05 to 5% by weight; the foregoing preferably constituting at least 98% by weight of the total composition. Optionally stabilizers may be added such as olefins, phenolic compounds, nitro aromatic compounds and/or quinones. Numerous monohydric alcohols are specified as well as polyhydric alcohols such as the butamediols and pentane-diols. During phosphatizing, the composition is maintained at its refluxing temperature. Initially, ferrous phosphate or steel wool may be added to the bath. The phosphatized surface may be subsequently baked under infra-red heat, treated with dry steam, chromatized or painted.
