PU Metal Catalysts
Under the name Kosmos® EVONIK offers a wide range of standard tin, bismuth and potassium based catalysts as well as high performance catalysts for polyurethane (PUR) and polyisocyanurate (PIR) applications.
The Kosmos® portfolio includes standard metal catalysts that meet the highest quality demands. Additionally customized catalyst solutions with a low emission profile for specific applications are offered.
Types of PUR foams requiring metal catalysts are flexible slabstock, flexible moulded foams, rigid lamination, spray foam or shoe sole systems. Non-cellular applications are elastomers, coatings, adhesives, sealants or cast resins.
Besides our metal catalysts we also offer amine catalysts, silicone surfactants, curing agents, color pastes and other performance additives from EVONIK for PUR formulations.
