Black silicon carbide F500 powder for water-based anti-corrosion industrial paints
Black silicon carbide F500 powder is made from fine processing, achieving a purity of up to 98.5%. Its high purity and good flowability make it an excellent ceramic filler in water-based anti-corrosion industrial paints. It can enhance the paint’s performance in terms of corrosion resistance, abrasion resistance, and weather resistance.
Abrasion Resistance Advantages
1. Silicon carbide powder itself has extremely high hardness and a dense crystal structure. When added to paint, it forms a hard, abrasion-resistant skeleton on the coating surface, significantly improving the paint film’s resistance to scratches, friction, and erosion.
2. The fine particle size and good dispersibility of SiC F500 ensure uniform distribution in the paint. That can prevent particle protrusions and balancing paint film smoothness and abrasion resistance, effectively extending the coating’s service life.
3. It exhibits outstanding resistance to sand and gravel erosion and mechanical wear. As a result, black SiC F500 is suitable for high-abrasion applications such as floor coatings, anti-corrosion topcoats, and equipment protective paints.
Advantages in Corrosion Resistance
1. Extremely stable chemical properties, resistant to acids, alkalis, salt spray, and organic solvents. It does not react with acidic or alkaline corrosive media and can block corrosive ions from penetrating the substrate.
2. Fills the microscopic pores of the paint film, creating a tightly sealed coating that prevents moisture, salt, and corrosive gases from penetrating the metal/substrate, reducing the risk of rust, corrosion, and peeling at the source.
3. The inert powder does not produce electrochemical corrosion. When used with an anti-corrosion primer, it forms a long-lasting composite anti-corrosion protection system.
Advantages in Weather Resistance
1. Silicon carbide powder is resistant to ultraviolet rays, aging, and high and low temperatures. It is not prone to chalking, discoloration, or cracking even after long-term outdoor exposure.
2. Improves the paint film’s resistance to weathering, rain erosion, and yellowing due to aging. It maintains good color and gloss in outdoor environments, ensuring the coating remains intact without fading or chalking for a long time.
3. It exhibits strong thermal stability, exhibiting no expansion or cracking under temperature variations. So it is suitable for weather-resistant paint systems used in outdoor steel structures, curtain walls, flooring, and construction machinery.
Black silicon carbide F500, as a functional filler in paints, is hard and wear-resistant, inert and corrosion-resistant, and resistant to sunlight and weathering. Simultaneously, its moderate fineness allows for easy dispersion and does not affect paint film application or appearance, making it an ideal functional filler for high-end wear-resistant, corrosion-resistant, and weather-resistant paints.
