GB/T 9267-2008 "Emulsions for coatings and polymer dispersions for coatings and plastics — Determination of white point temperature and minimum film-forming temperature" specifies the test methods for two key temperature indicators, applicable to relevant emulsion and dispersion products. The white point temperature is determined by observing the appearance changes of the sample during cooling-heating cycles, while the minimum film-forming temperature is assessed using a film-forming temperature tester. Testing requires instruments such as a minimum film-forming temperature tester, a constant-temperature water bath, and a microscope, providing data support for temperature control during coating application and product performance assurance.
