Zinc stearate is a white powder, insoluble in water, soluble in heat It contains organic solvents such as ethanol, benzene, toluene, and turpentine; it decomposes into stearic acid and corresponding salts when exposed to acids; it is a fire hazard under dry conditions, with an auto-ignition point of 900°C; it is hygroscopic.
Zinc stearate can be used as these additives:
1. It can be used as a non-toxic stabilizer for polyvinyl chloride with low initial coloration. Good weather resistance. This product is not easy to use alone because it has a significant catalytic effect on the degradation of polyvinyl chloride and can cause the product to change color rapidly after a period of time. Used in combination with barium and cadmium soaps for general soft products. The dosage of this product should not be too large, but when used in conjunction with epoxy compounds and phosphites, the dosage can be appropriately increased.
2. It can be used as lubricant for styrene resin, including polystyrene, ABS and SAN resin, and as a release agent for transparent products. In the rubber industry, this product can be used as a lubricant and diaphragm agent (anti-sticking) for rubber compounds. In addition, it can also be used as a textile polish, paint flattening agent and cosmetic ingredient.
3. Metal soap powder. Used in the creation of powders, pressed cakes, etc. Mainly used as an adhesive for perfume powder to increase the adhesion of perfume powder on the skin. Zinc stearate is light and soft. When added to powder cosmetics, it will coat other powders, making the powder easily permeable.
4. Anti-foaming agent, light and heat stabilizer. Paint smoothener and abrasive. Drying lubricant and release agent. Stabilizer, release agent and lubricant for plastic products. Waterproofing agent for concrete, brownstone, paper and fabrics
