CONSTRUCTION PANEL HAVING IMPROVED FIXING STRENGTH

摘要

A gypsum product has a first polymeric additive and a second polymeric additive distributed therein, wherein the first polymeric additive is a synthetic polymer and the second polymeric additive is starch. It has been found that the combination of starch and a synthetic polymer may result in one or more of the following advantages in the manufacture and performance of gypsum products: -increased strength; -greater ease of manufacturing due to the increased fluidity of stucco slurries containing both additives; and -increased resistance to hygroscopic expansion.
