This substance, called zinc stearate, is a colorless metal soap. As a water repellent agent, it is especially used in cement-based mortars, insulation materials and joint materials on surfaces where water repellency is required.
Zinc stearate is also used as a slider. It is also compatible with rubber and plastics. It is often used as a water repellent in building chemicals. It is used as dusting powder in rubber sector.
What Are The Properties Of Zinc Stearate?
Zinc stearate has a white appearance, fine powder and a structure that cannot be dissolved in water. When mixed with strong mineral acids, they decompose into stearic acid and its corresponding zinc sulfates. It is widely preferred as Plastic, Machinery Engineering, rubber, paint and ink industry lubricants, slider agents, heat stabilizers, mold release agents and accelerators.
Zinc stearate is used in water-based paints to improve transparency, anti-foaming, stability, fast drying sensitivity. In addition to being used as agent in water-based inks, it is also used as polishing agent to improve the surface hydrophobic structure of textile products in cosmetic products, to increase the smoothness of the surface, on the surface of thermal paper and special paper in the paper industry as a waterproofing agent, to increase abrasion resistance and water resistance for polishing paper, sanding polish property.
What Are The Technical Properties Of Zinc Stearate?
Zinc stearate is technical in terms of type, in terms of formula as [CH3(CH2)16COO]2Zn, white powder in terms of appearance, CAS no: 557-05-1, molecular weight 623.33 g/mole, humidity 0.98%, melting point 120-124 c, density 0.997 g/cm3 and in terms of solubility it has an insoluble structure in cold water.
What Are The Uses Of Zinc Stearate?
Zinc stearate is used as a stabilizer for plastics. It is preferred as a plasticizer in the plastics industry as in the cosmetic industry. It is used as a straightener and sandblasting agent in varnishes, coatings and inks.
Zinc stearate is applied in the tablet production and used as lubricant drying and pollinating agent for rubbers, as a catalyst in chemical synthesis, as a waterproof additive in concrete, rock wool (hard wool), textiles and paper and it is used as water repellent in cement-based insulation products.
How Should It Be Stored?
It should be stored in dry and cool places that do not contact with sunlight.
