Zinc Stearate (C17 H35 COO)2 Zn is is a soft, fine fluffy free flowing bulky powder having 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 mould releasing agent among all metal soaps. It contains no electrolyte and has a hydrophobic effect.
PROCESSING
Through Fusion Process : Zinc Stearate through fusion process has been used as lubricants in plastics, mould release agents for rubber, external lubricants for wire drawing and metal working and cosmetic emulsifier. In this process, Zinc Stearates are produced by adding stearic acid and zinc oxide. It is useful when heat stability is critical.
Through Precipitation Process : Zinc Stearate through precipitation process has a fine particle size and low residual mineral impurities. This is why its main applications are required in most paints, lacquers and industrial coatings. Through precipitation process, light weight Zinc Stearate is produced.
Important Properties :
The important properties of our Zinc Stearate, relevant to various applications are:
- Controlled Particle Size.
- Good Dispersion.
- Low Bulk Density.
