High Purity White Aluminum Oxide Powder Polishing Powder

Due to the characteristics of aluminum powder with metallic luster and parallel to the coating, in the carrier containing transparent pigment, the glossiness and color depth of aluminum powder change with the change of incident angle and angle of view of incident light, which is called "two-color effect". The aluminum powder is arranged in different layers in the coating film. When the incident light irradiates each layer of aluminum flake, the reflected light is obviously different in brightness due to the different weakening of the coating film through different thickness.

The aluminum powder is silvery white metal powder, with spontaneous combustion temperature of 5900 ℃ and dust explosion limit of 40mg/m3. Do not touch dilute acid or strong alkali. When a large amount of dust is damp, it will naturally heat up. The mixture of aluminum powder and other metal oxides will react violently or catch fire in case of fire. Mixing with halogen elements will cause fire. Explosive reactions may occur when heated or rubbed with halogenated hydrocarbons.
