Abstract: This invention relates to a composition suitable for use in making moisture resistant gypsum products. In particular, this invention relates to resin dispersions and their use in combination with gypsum to form moisture resistant gypsum compositions which are settable by hydration. Further, the invention relates to moisture resistant products formed from such settable gypsum compositions, e.g. panels and boards, and a method for the manufacture of such moisture resistant gypsum products.

Abstract: The present invention is directed to an adhesive composition, which comprises an epoxy resin, a coupling agent, filler, and an effective amount of an amine-curing agent or curative for said epoxy resin. Advantageously, tri-functional and/or tetrafunctional epoxy resins and/or acrylate monomers will be incorporated into the adhesive composition in order to reduce open time and enhance substrate adhesion. Advantageously, a mixture of amines will be used in the curative including aliphatic amines, which have low viscosities and efficiently wet the substrate for enhancing adhesion; polyamines, which can be used to manipulate open time and allow for improved ratio tolerance of the adhesive system; and amine-terminated rubbers (ATBN), which can improve impact resistance and the toughness of the cured adhesive. Preferred coupling agents are silanes.
