Abstract
Wax emulsions for the manufacture of wallboard include water; a lignosulfonic acid or a salt thereof; and at least one wax selected from the group consisting of slack wax, paraffin wax and montan wax. The emulsions may have a pH of between about 6.5 and 7.9. Such emulsions can provide enhanced moisture resistance to the wallboard.
