AQUEOUS WAX EMULSIONS HAVING REDUCED SOLIDS CONTENT FOR USE IN GYPSUM COMPOSITIONS AND BUILDING PRODUCTS

摘要

Aqueous wax emulsions are disclosed herein for use in gypsum formulations and other building products which emulsions include water; a paraffinic hydrocarbon; a montan wax component; and a hydrocarbon component. The hydrocarbon component is at least one hydrocarbon compound having from 5 to 20 carbon atoms or at least one hydrocarbon resin which is based on the at least one hydrocarbon compound as a monomer, wherein the resin is at least a dimer comprising the hydrocarbon compound and the resin has a molecular weight (Mw) of no greater than about 3,000, wherein the hydrocarbon component has a softening point of from about 22C to about 110C. Methods of making such emulsions are also provided.
