Polycat® 39

Technical Datasheet | Supplied by Evonik
It acts as a glycol diluted tertiary amine catalyst. Exhibits medium viscosity and low activity for easy on line dosing. Offers improved curing of rigid PUR systems and excellent performance in water co-blown rigid systems. Also offers delayed front end activity compared with strong blowing catalysts such as Polycat® 5. It is recommended for use as a co-catalyst with other polyurethane and polyisocyanurate catalysts, particularly in formulations with an isocyanate index of greater than 105–110. Used in a wide variety of rigid polyisocyanurate foam and non-foam applications.
