zinc stearate emulsion has many applications, including rubber, plastics, coatings, inks, paints, thermal paper and cosmetics. It can be used as a release agent, color retention agent and lubricant.

Generally speaking, zinc stearate is a white powder that is insoluble in water and has a slight fatty odor. It is produced from stearic acid by melting or heating it at high temperature.

It is widely used as a release agent, heat stabilizer and lubricant in the plastics, polyolefin and rubber industries. It is also used in the wood coatings (lacquer) industry as a polishing additive. It can be used to improve texture and abrasion resistance, and it is a good thickening agent for wood coatings.

The preparation method is as follows: selecting deionized water, add it into the dispersion machine, warm up to 6080degC, adding wetting dispersing agent, emulsifier, crosslinking agent, bactericide and suspending agent under stirring, and making its dispersion and emulsion, constant temperature 30-40 minutes.

After the emulsification is completed, water-based defoaming agents are added to quickly eliminate bubbles in the emulsion. Zinc stearate is then added and mixed until it is completely emulsified, then ground to a particle size of 0.5 to 1 micron.

This dispersion is characterized by being stable, low in viscosity and uniform, having ideal enhancing and lubricating effects. It can be stored for a long time without changing quality, does not appear phenomena of flocculation stratification, has no foam during the production process and is ideal in product quality.
