Zinc Stearate (C17 H35 COO)2 Zn is is a soft, fine fluffy free flowing bulk powder having a characteristic odor. Zinc soap repels water. We are manufacturing this via precipitation /Direct process using high-quality stearic acid. During manufacturing, the particle size, shape, Bulk Density, and purity is closely controlled to ensure product quality uniformity. Zinc Stearate is insoluble in polar solvents, such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene and chlorinated hydrocarbons) when heated. It is the most powerful mold releasing agent among all metal soaps. It contains no electrolyte and has a hydrophobic effect.
