The GB/T 9267-1988 standard specifies a method for determining the emulsion minimum film forming temperature (MFFT) for emulsion paints, which is applicable to emulsions for emulsion paints and Miscellaneous emulsions. This method uses a temperature layer formed on a metal plate, Spreader emulsion and then drying to determine the limit temperature for emulsion to form a continuous uniform transparent film. The standard includes equipment requirements, test procedures and result representation, providing a quality control basis for the Coatings industry.
