  • Applications

    Aluminum methionate (CAS 52667-15-9) can function as a metal chelating and stabilizing agent in formulations and processing, helping control metal ion activity in coatings, inks, and cleaning products. It may serve as an intermediate or coordination component in industrial polymer and plastic formulations, and can act as a crosslinking or curing aid in adhesives and coatings. It is sometimes evaluated as a precursor or processing aid in plastics and polymer composites, and may be used as a metal-ion sequestering additive in formulated products.
