Product Overview

Aluminium Stearate Extra Pure (CAS No. 637-12-7) is an aluminium salt of stearic acid classified as a long-chain metal carboxylate. Its structure combines an aluminium-containing carboxylate component with extended hydrocarbon chains, giving the material compatibility with many non-aqueous systems and useful influence over consistency, gel formation, dispersion, and resistance to water penetration. These characteristics distinguish aluminium stearate as a functional metal soap for formulation and materials-related work.

The Extra Pure grade is intended for routine laboratory formulation, preparative work, materials research, and application-development studies requiring a dependable aluminium stearate reagent. It is suitable for evaluating thickening, gelling, water-repellent, lubricating, and surface-modifying effects in oils, coatings, polymers, mineral compositions, and related experimental systems.

Typical Applications

• Thickening and consistency modification of lubricating oils
• Preparation and evaluation of greases, lubricants, and cutting compounds
• Gelling and rheology modification of alkyd paints and coating formulations
• Flatting and surface-finish studies in suitable coating systems
• Laboratory evaluation of water-repellent treatments for fabrics
• Waterproofing-additive studies involving cementitious and mineral materials
• Additive research in polyamide and thermosetting-plastic formulations
• Investigation of metal soaps in non-aqueous dispersions and materials systems

Aluminium stearate is documented for thickening lubricating oils, gelling alkyd paints, waterproofing fabrics and cement, preparing polymeric materials, and imparting water repellency to natural stone surfaces.
