Zinc stearate is in the form of white fine powder with high-temperature resistance. It is extremely resistant to water and provides excellent water-repellent properties to various applications. Having perfect non-stick properties, Zinc Stearate is frequently used in the polymer manufacturing industry.
Zinc Stearate has high purity, coloring, and dispersed ability. Zinc Stearate is mostly used as release agents and lubricants for plastics and rubber. In the paint and coatings industry, it helps to suspend pigments, improves grindability and gloss. It is also added as a flattening agent to lacquers. Moreover, it serves as a supply of zinc, which is a benefit in some processes like the manufacturing of PVC Stabilizer Ca/Zn based.
