Water-based sealer composition

摘要

A water-based sealer composition which forms a coating film having excellent adhesion to substrates. The composition comprises as the active ingredient an aqueous dispersion obtained by polymerizing a vinyl monomer by emulsion polymerization in the presence of a macromonomer having carboxyl groups. The aqueous dispersion highly infiltrates into inorganic materials such as a slate, calcium silicate plate, and cement mortar.
