Abstract: Hybrid spray foams utilize a urethane reactant, a crosslinker, and an (optional) epoxy and/or acrylic resin along with a blowing agent and rheology modifier to produce a quick-setting foam that remains in place until the foam forms and cures. The urethane reactant may be formed as an adduct with or without the use of isocyanate chemistry. In some embodiments, the polyurethane oligomer is made by reacting cyclocarbonates and di- or polyamines, while in other embodiments the polyurethane backbone employs the use of commercially available capped or blocked urethane oligomers made by any method. The oligomers contain reactive groups, typically at the oligomer ends, that crosslink with crosslinkers or with acrylic or epoxy resins to form hybrid polyurethane foams. Foams may also contain a plasticizer, and/or a surfactant as well as other optional additives. Methods of making such foams are also provided.

Abstract: The general inventive concepts relate to unbonded loose-fill fiberglass compositions useful for insulation. The compositions demonstrate high hydrolytic stability. In certain instances, this is accomplished by application of a surface modifier. In certain embodiments, the modifying agent is prepared by dilution and hydrolysis of a silane at a high solid content (i.e., hydrolysis at 25% to 60% solid).

Abstract: Foams for filling cavities and crevasses and for forming foamed products are provided. The latex foam may include an A-side containing a functionalized latex and a B-side that contains a crosslinking agent and optionally a non-functionalized latex. The A- and/or B-side contain a blowing agent package or components forming the blowing agent package. The blowing agent package may be the combination of two or more chemicals that when mixed together form a gas or a chemical compound that, when activated by heat or light, forms a gas. In an alternate embodiment, the latex foam includes a functionalized latex, an acid, and an encapsulated crosslinking agent and base. Alternatively, the spray latex foam may include a functionalized latex, a crosslinking agent, and an encapsulated dry acid and dry base. The encapsulating agent may be a protective, non-reactive shell that can be broken or melted at the time of application.

Abstract: An insulated cavity is provided. The insulated cavity includes a layer of foam material positioned over cracks and around penetrations occurring in portions of the cavity. A layer of insulative material is positioned in contact with the layer of foam material. The layer of insulative material is a mixture of foam material and loosefill insulation material.

Abstract: One- and two-part spray non-isocyanate foams that include an amide-based oligomer containing pendant carboxylic acid and a polyfunctional aziridine crosslinking agent is provided. The amide oligomer typically contains urea links, urethane links or both groups. Additionally, the foams may include one or more plasticizer, a non-functionalized resin, a surfactant, and/or a thickening agent or rheology modifier. The amide oligomer does not contain any isocyanate groups, and, as a result, there are no free isocyanate moieties generated during formation of the foam that may be potentially hazardous to workers installing the foam. The presence of the urethane segments on the oligomer permits for the generation of a polyurethane foam without the drawbacks of conventional polyurethane foams. The foams may be used to fill cavities, cracks, gaps and crevices, such as around windows and doors, and may also be used in flash and batt systems.

Abstract: A wet fiber based composition that includes wet glass fibers, a water dispersible polymeric resin, and gypsum is provided. Components including melamine formaldehyde, a filler material, coupling agents, acetic acid, an accelerator, and/or a hardener may also be added to the composition. The gypsum may be a-gypsum, B-gypsum, or combinations thereof. The wet glass fibers are wet chopped glass fibers or a wet continuous roving. The combination of the wet glass fibers, the water dispersible polymeric resin, and the gypsum have a synergistic effect that creates a composite product that is water resistant, fire resistant, and has improved mechanical properties. In one exemplary embodiment, the wet fiber based composition is used to form a gypsum board that can be molded into various composite products. In other exemplary embodiments, thin multi-ply gypsum boards may be formed by alternately layering glass mats with layers of a gypsum/polymer slurry.

Abstract: A one-part spray foam formed by Michael addition chemistry is provided. The foamable composition includes at least one electron donor, at least one electron acceptor, an encapsulated catalyst, and one or more blowing agents. The catalyst is a weak or strong base. The encapsulation of the catalyst controls the polymerization of the Michael addition compounds such that the catalyst can be added and/or activated at a desired time to begin the foaming reaction. The catalyst may be encapsulated in a high molecular weight inert polymer or wax. In some embodiments, the chemical blowing agent(s) are also encapsulated. To produce a foam according to the invention, a single stream of the foamable composition is fed into an application gun where the slurry is heated and mixed. The heat and/or mixing in the gun releases the catalyst, which initiates the reaction between the Michael donor and Michael acceptor to form the foam.
