Description and Uses
Aluminum stearate is a non-stoichiometric compound consisting of mono-, di-, and tri-forms where aluminum distearate is the main constituent, and it forms the stearic coating on aluminum alloy surfaces. It is added to paints, enamels, and varnishes to suspend pigments in oil, prevent separation, reduce the oil required to wet pigments, increase paint body by forming a gel, and flatten varnishes. Aluminum stearate dissolves in heated vegetable oils and coats the surface of pigment particles to prevent settling upon cooling and gelling[1-3].
Aluminum stearate is used for waterproofing fabrics and for thickening lubricating oils. It is involved in the preparation of polyamides and thermosetting plastics. It is used as a waterproofing additive in cements and in light-sensitive photographic compositions. It acts as a gelling agent for alkyd paints, as a defoamer for oil drilling fluids and as a retarder for polysulfide dental impression materials. Further, it is used in greases, lubricants, cutting compounds, cosmetics and pharmaceuticals. It serves as a flatting agent, as a defoaming agent in beet sugar and yeast processing. In addition to this, it is used as a water-repellent soap for natural stone surfaces.
