AQUEOUS SEALER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To develop a nonpollution type aqueous vinylidene chloride sealer composition for inorganic building materials such as houses having excellent moisture permeability resistance and designability at a low cost. SOLUTION: This aqueous sealer composition comprises (I) a vinylidene chloride emulsion and (A) a talc represented by the formula (1) Mg3 Si4 O10 (OH)2 (1) and is characterized as comprising the talc (A) in an amount of 10-300 pts.wt. based on 100 pts.wt. of solids in the vinylidene chloride emulsion (I).
