UV coatings, also known as photosensitive coatings or photocurable coatings, typically use ultraviolet radiation as the curing energy source and can quickly solidify into a film without the need for heating. UV-curable coatings can be applied to different substrates such as paper, PVC plastic, wood, leather, and other materials. Fused alumina powder is an important functional additive in UV coatings, in addition to photosensitive resins, film-forming agents, and photoinitiators. White aluminum oxide powder F240, F360, and F800 are commonly used grits.

White aluminum oxide 5-25 microns (also known as white fused alumina/white corundum 200mesh-0) is an extraordinary refractory powder. It is suitable for investment casting to make shells and molds in the lost foam process.  There are several significant advantages of the powder.

The diamond polishing pad is widely used for flooring polishing.  The main raw material is diamond grain and powder. Adding white aluminum oxide powder can improve sharpness and polishing efficiency. Generally, WFA particle size is smaller than that of diamond particles as the filling of diamond water grinding discs. White aluminum oxide powder 800 # and 1200 # are commonly used grits.

White aluminum oxide F220 is a common grit size for microdermabrasion in the Skincare field. It is a new skin-improvement method that uses the principle of epithelial tissue regeneration to spray microcrystalline particles at high speed to rub the deep layer of the epidermis, stimulate the rapid renewal of collagen and fibrous tissue, and evaporate or destroy skin cells instantaneously.

White fused alumina is shortly called WA. It is a basic abrasive material for cutting wheels and grinding wheels. Compared with brown fused alumina, white fused alumina is more suitable for sharp grinding because WA has a better self-sharpening feature. White fused alumina F60 is a major grit for WA grinding wheel.
