Collection: Polyurethane Catalysts

Polyurethane Catalysts — compiles metal and tertiary amine catalysts that accelerate the formation of urethane bonds between isocyanates and polyols, including the blowing reaction that produces polyurethane foam. The choice of catalyst type determines the balance between the gelling reaction rate and the gas-forming reaction during the foaming process.

Polyurethane Catalysts are used by foam manufacturers, protective coatings, adhesives, and sealants to control the rates of gelling and blowing reactions during polyurethane formation. Organotin-based catalysts are commonly used to accelerate the urethane reaction, while tertiary amines such as diethylaminoethyl ether derivatives play a greater role in the gas-forming reaction that determines foam cell structure.

Example products in this collection: TCI Z0006 17501-44-9 Tetrakis(2,4-pentanedionato)zirconium(IV), TCI D0134 280-57-9 1,4-Diazabicyclo[2.2.2]octane, TCI T3149 301-10-0 Tin(II) 2-Ethylhexanoate, TCI D0302 1067-33-0 Dibutyltin Diacetate, TCI T1618 3855-32-1 2,6,10-Trimethyl-2,6,10-triazaundecane, TCI D0303 77-58-7 Dibutyltin Dilaurate, TCI T1289 111-51-3 N,N,N',N'-Tetramethyl-1,4-diaminobutane, TCI D0649 108-01-0 2-(Dimethylamino)ethanol.

Distinguish metal catalysts, which tend to be selective for the gelling reaction, from tertiary amine catalysts, which play a greater role in the blowing reaction, and consider the volatility and compatibility of each with the polyol formulation used. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
