Types of bismuth-zinc catalysts
Thread Content
Environmental sustainability is the trend in the development of the polyurethane industry today. Since compounds such as lead, mercury, and tin can have adverse effects on human health and the environment, their use in this industry is strictly restricted. Environment-friendly catalysts for polyurethanes mainly include organic bismuth, organic zinc, and zinc-bismuth mixed catalysts, which can be widely used in the production of polyurethane coatings, resins, pastes, adhesives, sealants, elastomers, and other products in the PU industry. They represent an excellent alternative to toxic catalysts based on lead, mercury, and tin. Bismuth series: TMG 716/720/728 – Bismuth neodecanoate; Polyurethane coatings, adhesives, sealants, elastomers.
