Zinc Stearate

Description

CAS No.: 557-05-1

In its formal definition, zinc stearate is used as soap, a metal salt of a fatty acid. It’s a solid white substance that deters water. When heated, it becomes soluble in chlorinated hydrocarbons and aromatic hydrocarbons like benzene, but insoluble in polar solvents like ether and alcohol. Of all the metal soaps, it is the most effective mould releaser. It has a hydrophobic effect and is electrolyte-free. Its primary industries of use are plastics and rubber, where it finds value as a readily integrated lubricant and releasing agent.

High-quality fatty acids are used in the modified fusion process to create zinc stearate, which has the following qualities: excellent lubricity, excellent water repellent, good clarity, and weathering stabilization. Non-toxic, does not stain sulfur, and barely forms any color at first.
