摘要： A thin drywall board that includes a gel coat, at least one polymer/gypsum layer, and a wet glass fiber layer is provided. The gel coat is formed of a gel coat composition that includes a water dispersible polymer, gypsum, and optionally a crosslinking agent and/or a coupling agent. The polymer/gypsum layer is formed of a matrix composition that includes a water dispersible polymeric resin and gypsum. Components including melamine formaldehyde, a filler material, coupling agents, acetic acid, an accelerator, and/or a hardener may also be added to the matrix composition. The wet glass fiber layer is preferably a glass fiber mat. The combination of the water dispersible polymeric resin and the gypsum in the matrix composition have a synergistic effect that creates a thin drywall board that is water resistant, fire resistant, and has improved mechanical properties. A method of forming the inventive thin drywall boards is also provided.

摘要： This invention produces three-dimensional shapes such as window lineals by first lining a foam die with a continuously moving reinforcing veil. Once the veil is in the foam die, a foam is blown into the die. The foam expands in the die forcing the veil against the die wall. The veil is selected so that the foam never fully penetrates the veil, but adheres to it. The material exiting the foam die is now properly shaped to enter the curing die. Resin is then injected onto the foam core where it penetrates the veil, is cured in the heated curing die and exits as a finished product of a plastic skin adhered to a foam core with a veil sandwiched therebetween.

摘要： A method for producing a foam-containing structure. In a first embodiment, a defoamer is applied to the inner surface of an impermeable carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer on the inner surface. The foamed resin and liquid resin layer are cured to produce a foamed resin inner core and a solid resin outer layer. In a second embodiment, a permeable carrier is covered with an impermeable release material. A defoamer is applied to the carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer impregnating the carrier. The foamed resin and liquid resin layer are cured to produce a foamed resin inner core, the carrier as a facer material, and a solid resin layer impregnating the carrier. In a third embodiment, a defoamer and a catalyst are applied to a permeable carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer impregnating the carrier. At least a portion of the liquid resin layer contacts the catalyst and cures into a solid resin layer. The foamed resin and any uncured portion of the liquid resin layer are cured to produce a foamed resin inner core, the carrier as a facer material, and a solid resin layer impregnating the carrier.

摘要： In a method of making a linear composite member, a hollow carrier is provided having a cavity and an inner surface. A curable liquid or gelled resin is applied to the inner surface. A curable foam is introduced into the cavity. The foam contacts the resin when the resin is not more than partially cured, and preferably when the resin has a viscosity not greater than 250,000 centipoise at 25.degree. C. The foam and resin, which are preferably both polyurethanes, are cured together to form a linear composite member having a foam core and a hard resin skin formed integrally. In a preferred embodiment, a reinforcement material, such as a glass fiber web, is embedded in the resin skin.
