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.
