TIB KAT 617

TIB KAT 617 – Zinc neodecanoate for polyurethane applications

TIB KAT 617 is a widely used zinc catalyst for polyurethane systems. Thanks to the use of neodecanoic acid as a ligand, the product is highly compatible with numerous PU formulations. A related catalyst is TIB KAT 620, a zinc carboxylate with an octanoic acid-based ligand.

Compared to organotin catalysts, TIB KAT 617 has lower activity, which leads to extended pot life in 2-component systems. The catalyst is particularly suitable for curing at elevated temperatures and for aromatic isocyanate systems. Compared to TIB KAT 620, it also offers higher reactivity and improved color stability.

The recommended usage rate is 0.02–1.0 wt%, based on the total formulation.

TIB KAT 617 and its components are registered on numerous international regulatory lists, including US TSCA, EU REACH, and Canadian DSL, making them particularly suitable for multinational formulation projects.
