GREASES, LUBRICATING OILS: Aluminum Stearate gives excellent properties of transparency, stringiness and water repellency. It acts as a high temperature resistant when added in lubricants. Aluminum Stearate is used by ONGC for defoaming properties.
DRY LUBRICATION: Useful as a lubricant in metals processing, such as wire drawing, producing brighter products.
PAINTS, VARNISHES AND LACQUERS: Adequate for improving pigments suspension, control of viscosity and gloss, water resistance and improving brushing and penetration. It finds very wide application in paint industries for preparation of enamels and lacquers where it acts as thickening agent or suspending agent. It reduces sagging and setting of pigment and works as varnish drier. It is used as an important ingredient for water proofing in tarpaulin & textile industries.
PRINTING INKS: The high gelling properties of Aluminum Stearate are useful for thickening and suspension improving.
PLASTICS: It is used in as a lubricant in the production of Polyamides and Thermosetting plastics.
RUBBER: Used as dusting powders to prevent sticking of unvulcanised rubber sheet.
CONSTRUCTIONS: Recommended jointly with Calcium Stearate for improving the water resistance of concrete and cements.
