Aluminum Distearate (CAS 300-92-5) is a metallic soap in white powder form whose gelling behavior sits between the mono- and tri-stearate forms, serving as a flatting agent and thickener in solvent-based coatings and as an internal lubricant and mold release agent in plastics and rubber. Our Industrial Grade powder is optimized for use in solvent-based coatings and polymer processing.

It acts as an efficient flatting agent and thickener, providing controlled rheology and anti-sag properties in varnishes and lacquers. The product's hydrophobic nature makes it an excellent choice for moisture-proofing applications in harsh environments.

This chemical is particularly effective as a mold release agent and internal lubricant in the production of plastics and rubbers. It helps in achieving a uniform surface finish and reduces friction during high-speed extrusion or injection molding processes.
