Silane coated white fused aluminum oxide F180 for laminate flooring
【Product Name】：Silane coated white fused aluminum oxide
【Other Names】：White fused alumina, white fused aluminum oxide, white corundum, white corindon, white aluminum oxide, WA grit, WFA grain
【CAS No.】：1344-28-1
【EINECS No.】：215-691-6
Silane coated white fused aluminum oxide F180 for laminate flooring has the characteristics of high cleanliness, round particles and high bulk density. Adding it to the surface of the wood flooring, the concentration of the abrasive per unit area is good, which can improve the wear resistance coefficient of the wood flooring. At the same time, WFA also has corrosion resistance and high temperature resistance, which can improve the weather resistance of composite wood flooring. White corundum abrasive with silane costing has the advantage of improving the light transmittance of the wear-resistant layer.
Features：
- After washing, it has high cleanliness, no black spots, and good whiteness.
- After secondary shaping process, it has high bulk density.
- The particle size is consistent, and the mixed particles account for more than 90%.
- There are few cracks on the surface of the particles, and the finish is high. After being made into the wear-resistant layer of the wooden floor, it has good light transmittance.
- It has strong thermal stability, and the wear resistance at high temperature is not affected.
- The white fused corundum has a high refractory temperature, acid and alkali corrosion resistance, and good thermal performance.
