Why add water-based zinc stearate to the coating?

Zinc stearate is white powder, insoluble in water, soluble in hot organic solvents such as ethanol, benzene, toluene, turpentine, etc.; it will decompose into stearic acid and corresponding salt when encountering acid; it has fire hazard and spontaneous ignition point under dry conditions 900℃; It has hygroscopicity and strong hydrophobicity. Adding to water-based paint can improve the hydrophobicity of the paint and improve the feel of the film.

Most of the waterproof coatings in our country are mainly based on tar. The quality of this kind of coatings is not stable enough, the thickness of the coating film is uneven, and the service life of the waterproof layer is short, so it has not been widely promoted and applied.

The development direction of new varieties of waterproof coatings in my country is high-performance and multi-functional waterproof coatings. This kind of coating with water-based zinc stearate has the following functional characteristics: It will not change the performance and color of the surface of the processed object; The surface can be colored and decorated with design, and the material can be painted with a metallic effect; Long lasting It can prevent the erosion and damage of water, freezing and air pollution; It has self-cleaning ability, strong wind and rain can clean the dust on the surface to be treated, and it will be washed with high-pressure water without destroying its effect; The thickness of the coating is very thin, only 5~15µ m, so the effective area of coating is greatly increased, about 3 times that of traditional coatings, which effectively saves costs; It has 100% air permeability and maintains the original air permeability of the building substrate; Improves heat insulation performance, with Anti-ultraviolet performance to protect the original surface color. Can well meet the needs of the market.
