The objective of this research was to develop environment-friendly Hwangtoh binder for application of Hwangtoh for interior wall finishing materials in the housing. To mix with Hwangtoh powder, water soluble melamine-polyurethane copolymer (MPU) resin with ethylene-vinyl acetate copolymer (EVA), polyvinyl alcohol (PVA), CaCO3, and inorganic fillers were designed. Far infrared ray irradiation, total VOC (TVOC) emission behavior, surface bonding strength, and surface crack behavior were studied by comparing to epoxy/Hwangtoh blend as control. For TVOC emission behavior, the 20 L small chamber method was used and the results satisfied the requirements of the excellent grade of TVOC of Korea Air Clean Association. To utilize the advantage of Hwangtoh, such as high absorbency, self-purification, deodorizing, sanitizing properties, and radiation of far infrared rays in the field of modern housing, this study was the foundation to develop environment-friendly binders for Hwangtoh.
