Wear-Resistant Paint Additive White Fused Aluminum Oxide 8000# Fine Polishing Powder
White fused aluminum oxide powder is a grinding-grade electrofused alumina powder. It features high hardness, strong thermal stability, excellent wear resistance, uniform particle size distribution, stable chemical properties, and high refractory temperature. It is also widely used in wear-resistant coatings, industrial ceramics, and other industries.
White fused aluminum oxide powder is an excellent polishing powder for stainless steel, aluminum alloy, copper, glass, and other materials. White fused aluminum oxide powder from us is an electrofused aluminum oxide powder. It is an aggressive grinding powder with high hardness and good toughness. White aluminum oxide is suitable not only for direct polishing with a micro polishing machine but also for making lapping products such as polishing wax, polishing stone, polishing liquid, etc. In the meanwhile, white aluminum oxide is an ideal additive for wear-resistance coating and ceramics.
Features of Wear-Resistant Paint Additive White Fused Aluminum Oxide 8000# Fine Polishing Powder:
High purity of aluminum oxide (above 99.5%), resulting in high hardness, strong grinding ability, and high grinding efficiency.
Produced by water suspension process, ensuring more uniform particle size, no large particles, and no scratching of the workpiece surface.
Strong chemical stability, resistant to acids and alkalis, and insoluble in water.
Strong thermal stability, with wear resistance unaffected at high temperatures.
High whiteness, which does not affect the color of coatings and other products.
Wide range of applications, not only for grinding and polishing but also as an additive for coatings, ceramics, rubber, plastics, and composite materials.
Product Feature of white fused aluminum oxide powder
The Al2O3 purity is high (99% min). So the hardness & grinding ability is high with good grinding efficiency.
High wear-resistance. Even in high-temperature circumstances, the strength is still excellent.
The white fused aluminum oxide powder is suspension treated by water. So it is of flowability and easy to scatter.
Low oil absorption especially for water-based paint.
Neutral property with PH value around 7-8.
High whiteness. It doesn’t affect the color of paints or coatings adding Al2O3 powder.
Resistant to most corrosive alkali and acid. It doesn’t dissolve in water.
Resistant to high temperature up to 1900 °C.
Good particle size consistency without big size grains. So it prevents scratch on the grinding substrate.
