Aluminium Stearate

Aluminium Stearate is highly hydrophobic and feature outstanding transparency and excellent adhesion to metal surfaces. Due to their water repellency it is used as hydrophobic agents in the building industry.

Aluminium Stearate exhibits relatively high solubility in hydrocarbon solvents compared to other metallic stearates. It is insoluble in water, alcohol and ether; but is readily soluble in benzene, acids and common solvents when hot. It exhibits good gelling and thickening properties, excellent transparency and a synergistic effect with Zinc Stearate or Calcium Stearate.

Aluminium Stearate is used as a lubricant in the production of polyamides and thermosetting plastics. It is also used as a thickening agent in the production of varnishes and lacquers.
