Abstract (en)

[origin: WO2004009687A1] Provided herein are compositions which are useful as catalysts in the production of polyisocyanurate foams. The compositions of the invention comprise N, N, N'-trimethylaminoethyl-ethanolamine in combination with one other catalysts useful in promoting trimerization of isocyanates. By promoting trimerization, isocyanate content of the foam is decreased which leads to a foam having better burn properties over prior art isocyanurate foams. Decreasing the isocyanate content of a foam should also lead to quicker de-mold of a molded foam because of reduced stickiness.
