Zinc neodecanoate

Zinc neodecanoate (CAS 27253-29-8) is an organometallic zinc salt derived from neodecanoic acid, supplied as a colorless to light yellow liquid. It is commercially available under trade names including Bicat Z, Bicat ZM, Bicat 1365, Tegokat 616, and Zinc Ten-Cem. No E-code designation applies to this substance.

In polyurethane and silicone systems, zinc neodecanoate functions as a Lewis acid catalyst, accelerating crosslinking reactions between isocyanates and hydroxyl or silanol groups. In alkyd coatings, it acts as a drier co-catalyst, coordinating with primary driers to promote oxidative curing of the binder film. It also serves as a metal-based additive in lubricant formulations, where it reduces friction at metal contact surfaces.

Zinc neodecanoate is subject to REACH registration requirements for supply within the European Economic Area. It is typically offered in liquid form, packaged in drums or IBCs depending on order volume. Buyers should request safety data sheets confirming compliance with current CLP classification requirements.
