[Zinc stearate supply and sales] Application and key properties of zinc stearate in wood paint

Common wood coatings on the market are: nitrocellulose paint (NC paint) , polyurethane or polyester paint (PU paint), unsaturated polyester paint (PE paint), ultraviolet light curing paint (UV paint), acid curing paint (AC paint). Zinc stearate is mostly used in wood paint and home decoration paint.

1. Zinc stearate:

According to Beitehua, which supplies zinc stearate : Zinc stearate is a white powder, insoluble in water, soluble in hot ethanol, benzene, toluene, turpentine and other organic solvents; it decomposes into stearic acid and corresponding salts when exposed to acid; it is fire hazard under dry conditions. Autoignition point 900℃; hygroscopic. It is used as lubricant and release agent for styrene resin, phenolic resin and amino resin. At the same time, it also has the functions of vulcanization activator and softener in rubber. Can be used as heat stabilizer for PVC resin.

2. Application of zinc stearate in wood paint:

It is used as a filler Mainly used in wood primers, its main functions are:

Improve the sandability of the primer;

Give the primer a certain thixotropy and improve the dustproofness of the primer;

Improve the filling ability of primer.

3. Key properties of zinc stearate in coating applications:

Dispersion, transparency , polishability, foam stability, thixotropy, compatibility.

Good zinc stearate is easy to disperse, has high transparency, good polishability, unstable foaming, certain thixotropy and good compatibility.
