it is understood that zinc stearate is a white powder, insoluble in water, soluble in hot ethanol, benzene, and toluene , turpentine and other organic solvents; decomposes into stearic acid and corresponding salts when exposed to acid; has fire hazard under dry conditions, auto-ignition point is 900°c; is hygroscopic. aqueous emulsions of zinc stearate are called aqueous zinc stearate.
the application fields and functions of water-based zinc stearate are as follows:
1. mainly suitable for water-based alkyd, water-soluble polyurethane, water-soluble acrylic, systems such as acrylic emulsion are excellent transparent putty fillers that are easy to polish and have anti-settling effects.
2. water-based coatings: used for high-quality water-based coatings with good transparency, fast defoaming, good stability, good anti-settling properties, fast drying, easy dispersion, easy grindability, and improved coating surface it has outstanding hydrophobicity and improves the feel of the paint film.
3. water-based ink: it has good economy, filling, stability, anti-settling and waterproof properties, and can be used as a flattening agent.
4. textile products: can be used as a polishing agent to improve the hydrophobicity of the surface.
5. cosmetic products: can be used as lubricants to improve the smoothness of the surface.
6. papermaking industry: it can be used as a waterproof and anti-adhesive agent for surface waterproof coatings on specific paper, thermal paper, coated paper, self-adhesive paper, etc. it has good lubrication and stability effect.
7. grinding sandpaper: can be used as a grinding aid to improve the surface’s polishing, abrasion resistance, and waterproof properties.
