BINDER COMPOSITION AND PROCESS FOR THE PRODUCTION OF A BOARD USING THE SAME

摘要

An isocyanate-base binder composition for use in a process for manufacturing hot-press molded boards from lignocellulose and inorganic material as the principal feedstock, wherein the releasability of boards from a hotplate is well kept for long and the system productivity is remarkably improved, thus providing boards excellent in various properties and reduced in the coefficient of expansion due to moisture absorption. The binder composition contains a compound (A) having at least two isocyanate groups, a low-molecular-weight polyethylene (B) and water (C) as the essential components.
