CAS 34364-26-6 20% Bismuth Neodecanoate Catalyst For Coatings 62804-17-5

Bismuth Neodecanoate - Description

Bismuth Neodecanoate is an organometallic compound where bismuth is coordinated with neodecanoic acid. It is widely used as a catalyst in the production of polyurethane, polyesters, and other polymer systems. Bismuth-based catalysts like bismuth neodecanoate are preferred for their low toxicity compared to traditional tin-based catalysts, making them an environmentally friendly option for industrial applications. It is typically supplied as a clear to slightly yellow liquid with high thermal and chemical stability.
