Spray Foam Catalysts | VALIKAT Bi 

Bismuth Catalysts for Polyurethane Spray Foam Insulation

Our VALIKAT bismuth catalysts are top-quality, fast-curing, bismuth-based metal carboxylates used for polyurethane spray foam applications. Unlike commonly used organotin catalysts like DiButylTin DiLaurate polyurethane catalysts (DBTL), our bismuth products are a sustainable alternative thanks to their low toxicity and eco-friendly nature, without compromising on exceptional reaction performance. Moreover, our products are compatible with amine catalysts. 

Selecting the right polyurethane catalysts is crucial for achieving the perfect curing profile, structural stability, and foam density. Find the ideal match for your desired formulation and end-properties in the overview below!
