Title:
ANTIFOAM COMPOSITION FOR AQUEOUS WOOD PAINT
Document Type and Number:
WIPO Patent Application WO/2019/119908
Kind Code:
A1
Abstract:
An antifoam composition for aqueous wood paints. Firstly, reacting a trimethyl-terminated polydimethylsiloxane, a hydrogen-containing organosilicone resin, a cage-type polysilsesquioxane POSS and silica to prepare an organosilicon antifoam active material, then synthesizing a silicone polyether of a specific structure, and finally compositing the synthesized organosilicon antifoam active material, the silicone polyether and polyether, such that the final antifoam composition is obtained. The antifoam composition is used in aqueous wood paints, and has excellent antifoam properties and compatibility.
