PAINT BINDER FOR FORMING SELECTIVE ABSORPTION COATING FILM FOR SOLAR HEAT RADIATION

摘要

PURPOSE:To prepare the binder for the titled paint, maintaining low thermal emissivity and having excellent heat resistance and weatherability, by using acrylic acid, methacrylic acid or their derivative as a main component. CONSTITUTION:To prepare a paint binder for forming a selective absorption coating film for solar energy radiation to the surface of a metallic substrate, etc., by using acrylic acid, methacrylic acid, or their derivative such as acrylic acid ester, methacrylic acid ester, etc. as a main component. USE: Applied to the surface of a heat collector to collect the solar energy.
