AGGREGATE-CONTAINING EMULSION COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an aggregate-containing emulsion coating material which reduces leakage with time of a water soluble component such as a surface active agent from a protective coating film after applying a polymer based waterproof sheet and has good coating operational/finishing properties and good coating film drying characteristics. SOLUTION: The aggregate-containing emulsion coating material is used for protecting a polymer-based waterproof sheet and is of a system which does not require or reduces the addition of a dispersing agent (a surface active agent). This coating material has a coating film-forming resin (a binder), aggregate and an aqueous solvent as essential components. A nonslip amount of the aggregate is incorporated into the coating film-forming resin. Further, colored aggregate is incorporated as the aggregate and a glycol is incorporated into the aqueous solvent to be adjusted so as to enable uniform coating and to have a predetermined drying rate.
