Wollastonite Powder

Description

Wollastonite Powder, also known as Calcium metasilicate. It is a calcium inosilicate with the formula CaSiO3.

The coatings industry widely utilizes Wollastonite as a functional filler. It has excellent physical and chemical properties. It offers several advantages as an essential coating additive, providing improved performance and quality coatings.

Wollastonite has excellent whiteness performance in the coating industry, one of its most important advantages. Whiteness, a significant measure of color brightness and purity in paint products, is one of its most essential features. By optimizing the crystal structure and particle morphology, Wollastonite achieves a highly white color effect. Consequently, coatings possess incredible hiding power and color consistency. The high whiteness of Wollastonite imparts a bright and clean appearance to painted surfaces, enhancing their visual appeal. It effectively conceals base colors, hides imperfections, and enhances color vibrancy. Whether applied to interior walls, furniture coatings, or high-end decorations, Wollastonite delivers excellent whiteness performance to meet diverse application requirements.

As a filler and reinforcing agent, Wollastonite can significantly improve coatings’ hardness and wear resistance. Particles of Wollastonite fill the paint, filling the voids and increasing the compactness of the layer. This makes the paint surface more rigid and more resistant to daily wear, scratches, and friction, extending the life of the paint.

Wollastonite can also improve the settling resistance and stability of coatings. The unique particle shape and surface treatment technology enable wollastonite particles to have good dispersion and suspension properties. They can evenly distribute in the paint matrix, preventing particle sedimentation and delamination. This helps improve paint uniformity and stability, resulting in a more consistent coating quality.

Wollastonite also enhances the fire performance and weather resistance of the coating. It has good high-temperature resistance, which can effectively isolate heat conduction and reduce the temperature rise of the coating surface. In addition, it can also resist the erosion of ultraviolet radiation and chemical substances, increase the weather resistance of the coating, and give the layer a longer service life in the outdoor environment.
