涂料表面干燥试验 小玻璃球法
Application Summary AI generated
This standard specifies a method for determining the surface-drying time of paints and varnishes by applying glass ballotini (small glass beads) to the coated surface and observing whether they can be brushed off without damaging the film. It is used in quality control and R&D laboratories within the coatings industry to assess the drying stage of solvent-based and water-based coatings. The test is particularly relevant for evaluating industrial and decorative paints where handling or recoating must occur after a specific drying interval.
