ある。(Prior art and problems to be solved by the invention) Conventionally, moisture-curing urethane, solvent-based resins, etc. with relatively low molecular weights have been used as resins for inorganic porous sealers. The former has become a problem due to its 11X property, and the former has become a problem due to the risk of fire and environmental pollution due to the use of organic solvents, and there is a strong demand for water-based products. As water-based sealers, various types of sealers based on water-soluble resins and water-dispersible resins have been studied. Currently, there are no water-based sealers available that are important for long-term durability, as the ingredients have poor Ω temperature resistance and adhesion to the base material.
