Abstract
Corrosion preventives, e.g. for automobiles, comprise sepiolite clays with waxes, sulfonates e.g. SACI, optional solvents, oils, soaps provide high viscosity, high solids, corrosion-preventatives. Application can be by hot spray or hot melt, hot dipping, and other standard techniques. The sepiolite clays provide excellent anti-sag capabilities to the dry films without excessively increasing the viscosity of the coating material. Conventional thixatropes such as bentonites and other common organo clays usually drastically increase product viscosity and complicate pumping at room temperature.
