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.
