LATEX COMPOSITIONS USEFUL AS BINDERS IN COMPOSITE BOARD HAVING DIMENSIONAL STABILITY AND STRENGTH

摘要

This invention relates to polymeric latexes with a relatively high Tg such as styrene, butadiene and acrylic acid or methyl methacrylate, ethyl acrylate and fumaric acid, which can be used in whole or in part as a binder to produce strong composite board that will not sag substantially under conditions of high temperature and humidity. The binder composition comprising the polymeric latexes serves as a partial or complete replacement for starch which is used as a binder for composite boards such as ceiling tiles.
