Ethanol CAS 637-12-7
Product Overview
Aluminum Stearate is an organometallic compound formed by the reaction of stearic acid with aluminum salts. It appears as a fine white powder and is insoluble in water but dispersible in organic solvents. It is widely used as a functional additive in industrial systems requiring water resistance, lubrication, and rheology control.
