The present invention provides a reactive catalyst composition for making a water blown flexible polyurethane foam. The catalyst composition comprises one or more tertiary amine catalysts in combination with (1) 2-methyl-1,3-propanediol or (2) a blend of 2-methyl-1,3-propanediol and a C7+ alkanol. The use of such catalyst composition improves the physical properties of the polyurethane foam.

Catalyst compositions for improving polyurethane foam performance

Methods for preparing polyurethane flexible foam are described, wherein an organic polyisocyanate is reacted with an active hydrogen-containing component such as an organic polyol, in the presence of a urethane catalyst, a blowing agent, optionally a cell opener, and a siloxane-based surfactant composition as a stabilizer for the foam. The siloxane-based surfactant composition comprises a silanol-functionalized organosiloxane having general formula (I), wherein:the R groups are independently a C-Calkyl, phenyl, or &#x2014;OSi(R); provided that at least one R group is a hydroxyl (&#x2014;OH) bonded directly to any silicon atom and X is an integer from 0-200.

Silanol-functionalized compounds for the preparation of polyurethane foams

Catalyst compositions for use in forming polyurethane products include a gelling catalyst, a trimerization catalyst, and a cure accelerator. The gelling catalyst is a tertiary amine, mono(tertiary amino) urea, bis(tertiary amino) urea, or a combination of any of these. Any known trimerization catalyst may be used. The cure accelerator may be a diol having at least one primary hydroxyl group, and having from five to 17 chain backbone atoms chosen from carbon, oxygen, or both between the hydroxyl groups, provided that at least five of the backbone atoms are carbon. Alternatively or in addition, the cure accelerator may be a polyol having three or more hydroxyl groups, at least two of which are primary, and having molecular weights between 90 g/mole and 400 g/mole. Delayed initiation of the polyurethane-forming reaction and/or reduced demold time for producing the polyurethane part can be obtained by using these catalyst compositions.

Fast demold/extended cream time polyurethane formulations

The present invention relates to a method for preparing a polyurethane foam which comprises reacting an organic polyisocyanate and a polyol in the presence of water as a blowing agent, a cell stabilizer, a gelling catalyst, and a tertiary amino alkyl amide catalyst composition. The catalyst composition is represented by the formula I: wherein R, R, R, R, R, R, A, and n are as defined herein and wherein the tertiary amino alkyl amide catalyst of formula I is acid-blocked.
