CURABLE ACRYLIC TOPCOATING COMPOSITION FOR SHUTTERING BOARDS FOR CONCRETE, SHUTTERING BOARDS FOR CONCRETE, AND PROCESSES FOR PRODUCTION OF THE SHUTTERING BOARDS

摘要

[PROBLEMS] To provide shuttering boards for concrete which can be used repeatedly many times, processes for the production of the shuttering boards, and a topcoating composition suitable for the shuttering boards. [MEANS FOR SOLVING PROBLEMS] A topcoating composition comprising an acrylic resin having curing hydroxyl groups, a polysiloxane, and an isocyanate curing agent; a shuttering board for concrete constituted of a base board, and a seal coat (A) made from a curable acrylic resin composition, an intermediate coat (B) made from another curable acrylic resin composition, and a top coat (C) made from the above topcoating composition or the like, which coats are formed on the surface of the base board in this order, and a process for the production thereof; and a shuttering board for concrete constituted of a base board, and a seal coat (A') made from a curable acrylic resin composition or the like, an intermediate coat (B') made from a moisture-curable urethane resin composition, and a top coat (C') made from a curable acrylic resin composition, which coats are formed on the surface of the base board in this order, and a process for the production thereof.
