ZINC STEARATE AND APPLICATIONS

Zinc stearate is a "zinc soap" that is widely used in industry. Zinc Stearate is formed by combining stearic acid with zinc oxide, the resulting compound is a white powdery organic compound that is insoluble in water.

Some industrial uses for Zinc Stearate:

a. Vulcanized rubber:

 Zinc stearate can be used as an “activator” for vulcanization because zinc has a beneficial effect on the reaction of sulfur with polyolefins. Zinc stearate facilitates dispersion because of its high solubility in the polar region of polyolefins. It acts as an antacid to polyolefins, contributes to color stability, and prevents corrosion.

b. Plasticizers and color additives:

Like other stearates, it has a wide range of applications in the plastics industry. As a pigment dispersant in Masterbatch. Because of its transparent properties, it should be used in impact glass applications, such as polystyrene for glass and other clear polymers. Zinc stearate is also used as a lubricant and stabilizer in PVC production.

c. Varnishes and paints:

In its best form, zinc stearate has transparent properties and is used in the manufacture of varnishes and paints.

It has good dispersibility and acts as a concealer for surface imperfections and as a thickener. In addition, zinc stearate protects the paint from moisture thanks to its water-repellent properties.

d. Cosmetics:

Zinc Stearate acts as an anti-caking agent in powdered cosmetics. Other uses of Zinc Stearate in cosmetics include as a lubricant, as well as a thickener to enhance texture.
