Bis(2-ethylhexanoato)hydroxyaluminum is primarily used as a catalyst in various chemical reactions, particularly in the production of polyesters and polyurethanes. Its effectiveness in accelerating polymerization processes makes it valuable in the manufacturing of coatings, adhesives, and elastomers. Additionally, it is employed as a stabilizer in PVC and other plastic materials, enhancing their thermal stability and durability. In the pharmaceutical industry, it serves as an active ingredient in antiperspirants, where it helps reduce sweat production by temporarily blocking sweat glands. Its versatility also extends to its use in lubricants and greases, where it improves performance under high-temperature conditions.
