This standard aims to provide a comprehensive set of product quality and technical specifications for synthetic resin emulsions used in interior and exterior wall coatings for buildings. It primarily covers product classification, technical requirements with corresponding test methods, and inspection rules. It is applicable to water-based emulsions produced via emulsion polymerization of monomers such as styrene and acrylates. The testing items specified in the standard are highly comprehensive, encompassing both fundamental and physical performance tests, including non-volatile content, pH value, viscosity, minimum film-forming temperature, freeze-thaw resistance, and various stability tests (e.g., mechanical stability). Additionally, it introduces requirements for the mechanical properties such as tensile strength and elongation at break, as well as limits for harmful substances like aromatic hydrocarbons, formaldehyde, and alkylphenol ethoxylates (APEO). To complete these tests, a range of specialized instruments is required, such as a rotational viscometer for measuring viscosity, a specialized instrument for determining the minimum film-forming temperature, an electric blast drying oven for preparing and conditioning samples, and chromatographs for precise analysis of harmful substances.
