Abstract

A novel compact, water-resistant material (I), based on ground cellulosic material, is repulpable and contains: (A) an organic binder selected from starch (or derivs.), flour, proteins, starch mfr. by-products, cellulose (or derivs.), hemicellulose (or derivs.) and mixts.; and (B) an organosilicon or fluorinated acrylic copolymer hydrophobic agent to provide water resistance.
