Abstract
Anti-crevice corrosion sealants for metals obtained by adding a mixture of zinc powder and dicyclohexylammonium nitrite powder bound by a vinyl silane coupling agent to a film-forming polystyrene dissolved in a solvent can restrain crevice corrosion occurring at crevices or jointed interior surfaces by filling the sealants into a fine crevice formed between the elements of metal machinery and tools or onto the jointed interior surface of the elements.
