Grey calcium powder, primarily calcium hydroxide, enhances the quality of coatings by improving adhesion, water resistance, and durability. With good whiteness and fineness, it is non-toxic and tasteless, making it ideal for various applications, including putty and thermal insulation mortar. Complying with national safety standards, it offers an environmentally friendly solution for coating enterprises, helping to lower production costs.

Grey calcium powder, mainly composed of calcium hydroxide Ca (OH) 2, has the characteristics of good whiteness, high fineness, non-toxic and tasteless, and can improve the adhesion, water resistance, scrub resistance, mildew resistance and moisture absorption characteristics of the coating, so as to improve the product quality and reduce the cost for the coating enterprises.

Application of lime and calcium powder in coatings

From the perspective of materials, lime powder is a white powder of 325~600 mesh which is grinded by lime through selective processing.

Take putty powder as an example. The main raw materials are lime and calcium powder (adding proportion of 30%), heavy calcium powder and rubber powder binder. They are mixed by dry powder mixer. The product is environmentally friendly, non-toxic and tasteless. It is divided into internal wall and external wall. Exterior wall putty should resist the wind and sun, so its adhesive strength is high. Interior wall putty, with good comprehensive index, environmental protection, non-toxic and tasteless.
