The GB/T 1750-1979 standard is used to evaluate the leveling of coatings, including two test methods: brushing method and lame plating method. The standard measures the levelling time of the coating on a flat substrate, using the time for the brush pattern to disappear and the surface of the paint film to smooth as an indicator. The test involves using a paint brush or spray gun Coating and observing the levelling performance of the paint film under constant temperature and humidity conditions to ensure the uniformity and smoothness of the coating.
