Zinc Stearate
Zinc stearate is a fine, creamy-white powder. It is the zinc salt of stearic acid. It is insoluble in water, alcohol and ether. It dissolves well in aromatic compounds like benzene and chlorinated hydrocarbons on heating. In fact, zinc stearate is strongly hydrophobic.
Zinc stearate is widely used as a binder, release agent, lubricant and vulcanization activator in the rubber and tire industry.
