Abstract

A stable polyol pre-mix composition comprises a blowing agent, a polyol, a surfactant, and a catalyst composition comprising an oxygen-containing amine catalyst and a metallic salt. The oxygen-containing amine catalyst may be, for example, one or more of an alkanol amine, an ether amine, or a morpholine group-containing compound such as, for example, 2-(2-dimethylaminoethoxy)ethanol or N,N,N′-trimethylaminoethyl-ethanolamine. The metallic salt may be, for example, alkali earth carboxylates, alkali carboxylates, and carboxylates of metals selected form the group consisting of zinc (Zn), cobalt (Co), tin (Sn), cerium (Ce), lanthanum (La), aluminum (Al), vanadium (V), manganese (Mn), copper (Cu), nickel (Ni), iron (Fe), titanium (Ti), zirconium (Zr), chromium (Cr), scandium (Sc), calcium (Ca), magnesium (Mg), strontium (Sr), and barium (Ba).

First claim

What is claimed is:

1. A stable polyol pre-mix composition comprising a hydrochlorofluoroolefin blowing agent, a polyol, a surfactant, a catalyst composition comprising an oxygen-containing amine catalyst selected from the group consisting of N-(3-dimethylaminopropyl)-N,N-diisopropanolamine; N,N-bis(3-dimethylaminopropyl)-N-isopropanolamine; 2-(2-dimethylaminoethoxy)ethanol; N,N,N′-trimethylaminoethyl-ethanolamine and mixtures thereof, and a metallic salt comprising magnesium formate.

2. The stable polyol pre-mix composition of claim 1 , further including a solvent.

3. The stable polyol pre-mix composition of claim 1 , wherein the blowing agent further comprises one or more hydrocarbons, alcohols, aldehydes, ketones, ethers/diethers, or CO 2 generating materials, or combinations thereof.

4. The stable polyol pre-mix composition of claim 1 , wherein the surfactant is a silicone or non-silicone surfactant.

5. The stable polyol pre-mix composition of claim 4 , wherein the surfactant is a polysiloxane polyoxyalkylene block co-polymer silicone surfactant.

6. A stabilized thermosetting foam blend which comprises:
(a) a polyisocyanate and, optionally, one or more isocyanate compatible raw materials; and
(b) a polyol pre-mix composition which comprises a hydrochlorofluoroolefin blowing agent, a polyol, a surfactant, and a catalyst composition comprising an oxygen-containing amine catalyst selected from the group consisting of N-(3-dimethylaminopropyl)-N,N-diisopropanolamine; N,N-bis(3-dimethylaminopropyl)-N-isopropanolamine; 2-(2-dimethylaminoethoxy)ethanol; N,N,N′-trimethylaminoethyl-ethanolamine and mixtures thereof and a metallic salt comprising magnesium formate.

7. The stabilized thermosetting foam blend of claim 6 , further including a solvent.

8. The stabilized thermosetting foam blend of claim 6 , wherein the blowing agent further comprises one or more hydrocarbons, alcohols, aldehydes, ketones, ethers/diethers, or CO 2 generating materials, or combinations thereof.
