Silicon Powder For Powder Coating

Silicon powder for powder coating is a kind of inorganic non-metallic functional filler with excellent properties. It is a kind of silica powder material which is processed by acid pickling, high purity water treatment, flotation, crushing, ball milling (or air jet milling) and other processes.

It has the characteristics of high purity (SiO2≥99%), uniform particle size distribution, high whiteness, high hardness, low water content, excellent acid and alkali corrosion resistance, good high temperature resistance, wear resistance, low linear expansion coefficient, good insulation coefficient, etc.

Silicon powder is widely used in silicone rubber, potting compounds, floor coatings, and powder coatings due to its excellent filling properties. Adding silicon powder enhances material surface hardness and scrub resistance, while partially replacing imported titanium dioxide to reduce costs. It is an indispensable functional filler in the electrical and electronic industries.
