Storage-stable two-component polyurethane or polyisocyanurate spray foam compositions are disclosed, said compositions comprising: (a) an A-side component comprising one or more polyisocyanate and one or more blowing agent; and (b) a B-side component comprising one or more polyol and one or more blowing agent comprising pressurized gaseous carbon dioxide and one or more liquid blowing agent; wherein both the A-side component and the B-side component, separately, generate less than 300 ppm of fluoride ion after one week of aging at 50 C.

Foam compositions are provided. The compositions are prepared from multi-functional acetoacetate esters and multi-functional amines or acrylates. The foam compositions can include one or more additives. The foam compositions can be used for home and commercial insulation, air sealing, sound proofing, structural improvement, and exterior roofing, among other applications. The foam compositions provide advantages of being isocyanate free and offer reduced exposure to isocyanate.

Disclosed are the use of fluorine substituted olefins, including tetra- and penta-fluoropropenes, in a variety of applications, including in methods of depositing catalyst on a solid support, methods of sterilizing articles, cleaning methods and compositions, methods of applying medicaments, fire extinguishing/suppression compositions and methods, flavor formulations, fragrance formulations and inflating agents.

Disclosed are methods of forming foam comprising: (a) providing a foamable composition comprising an isocyanate, a polyol and a physical blowing agent comprising at least about 50% by weight of hydrohaloolefin, including trans1233zd, and wherein the polyol comprises a polyol or mixture of polyols such that the hydrohaloolefin, including trans1233zd, has a solubility in said polyol of less than about 30%; and (b) forming a foam from said foamable composition.

A formulation technology for low pressure two component polyurethane foam-funning compositions containing gaseous hydrohaloolefin blowing agents is described with improved storage stability and extended shelf-life. The B-side component of the formulations contain a gaseous hydrohaloolefin blowing agent and a polyol pre-mix, the polyol pre-mix comprising liquid blowing agent, polyol, and a catalyst containing at least one catalytic metal compound.

A system for the application of foamable chemical compositions is presented. The application system comprises an ergonomic handle/adapter removably attachable to a pressurized source of a foam product, the handle having inlet and outlet orifices or openings for flow of the foam product from the pressurized source to a nozzle, the nozzle having an outlet orifice for dispensing the foam product and an inlet orifice for connecting to a flexible tubular connecting member which interconnects the outlet orifice of the handle/adapter with the inlet orifice of the nozzle. The nozzle of the present invention includes design features to produce a fan shaped spray pattern of the foam product and to reduce the incidence of leakage or dripping of either moisture or the foam product at the nozzle's outlet. The tubular connecting member is flexible and therefore allows a user to spray foam into hard to reach places.

Foam compositions are provided. The compositions are prepared from multi-functional acetoacetate esters and multi-functional amines or acrylates. The foam compositions can include one or more additives. The foam compositions can be used for home and commercial insulation, air sealing, sound proofing, structural improvement, and exterior roofing, among other applications. The foam compositions provide advantages of being isocyanate free and offer reduced exposure to isocyanate.

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

Foamable waterborne dispersions which form stable flexible foams under ambient cure conditions are disclosed, said foamable waterborne dispersions comprising: a polyurethane polymer formed from one or more aliphatic or cycloaliphatic polyisocyanate and at least two different polymeric polyol components selected from polyether polyol, polyester polyol, and polycarbonate polyol; wherein the ambient cure conditions include a temperature of from 4 C. to 32 C., and a humidity of 0% relative humidity to 90% relative humidity. Also disclosed are the flexible foams produced from the foamable waterborne dispersions, as well as methods of providing a space filling layer or space filling volume adjacent to or on a surface, said methods comprising applying to said surface a foamed sample of the foamable waterborne dispersions, and allowing the foamed sample of foamable waterborne dispersion to dry under ambient conditions to yield a stable flexible foam.

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.
