POWDER MIXTURE FOR MAKING AN UNDERCOATING AGENT FOR STEEL SURFACES

摘要

The invention concerns a zinc-containing corrosion-protecting undercoating agent for steel surfaces. The undercoating agent, which contains no organic solvents, consists of a mixture of dry, water-emulsifiable dispersion agent in powder form and water-reactive zinc in powder or flake form which are mixed with water immediately before treatment. The corrosion-protection properties of undercoating agents prepared in this way are as good as those of prior art single-component zinc-dust undercoating agents using only organic solvents.
