Abstract

Compositions based on wax emulsions and particulate inorganic compounds for improved water repellency are described, based on wax emulsions and particulate inorganic compounds for improved water repellency comprising, as a percentage of the total composition, 5% to 90% water, 0.01% to 20% surfactants, 2% to 90% waxes and 2% to 90% particulate inorganic compounds with a particle size of between/among 0.01 μm and 1000 μm, selected from among unmodified phyllosilicates such as agalmatolite, potassium aluminosilicate, talc, manganese silicate, or mixtures thereof in any proportion, added before or after the emulsification of the said waxes, and presenting a synergistic effect of increased water repellency when the said compositions are applied, preferably on reconstituted wood, composite panels.
