Low-Odor Catalyst for Isocyanate-Derived Foams and Elastomers

摘要

Provided herein are catalysts useful in providing foam products which are produced using an organic poly isocyanate as a starting material. A catalyst according to the present invention includes the tris-(hydroxyethyl)methyl ammonium cation, and optionally potassium cation, in combination with a variety of possible counter anions present to maintain charge balance and for compatibility. A catalyst according to the invention is preferably used in conjunction with one or more conventional tertiary amine catalysts in a foam producing process. The foams may be polyurethane foams, polyisocyanurate foams, flexible foams, or elastomeric foams.
