Aluminium Oxide is a white amorphous powder, commonly known as bauxite, the density of 3.9-4.0g/cm3, the melting point of 2050 DEG C, the boiling point of 2980 ℃, insoluble in water, is an amphoteric oxide, soluble inorganic acid and alkaline solution, there are four kinds of isomers with beta alumina. - V - A - alumina alumina alumina, mainly alpha and gamma type two variants, the industry can be extracted from bauxite.

Function:
1. The product has the property of anti-aging and protection from UVR (ultraviolet radiation), and greatly improve adhesion strength of products.
2. The product has uniform particle size, big surface area, good dispersion and transparency, and has good property of anti-UV.
3. It has good compatibility with paint and coatings.
