Application Summary AI generated

This standard specifies a test method for evaluating the flexibility of putty coatings by bending a coated metal panel around a series of cylindrical mandrels of decreasing diameter. It is applied in the paint and coatings industry to assess the resistance of putty films to cracking or detachment when the substrate is deformed, particularly for products used on automotive bodies, building panels, or metal furniture. The test is critical for quality control in manufacturing and material selection to ensure the putty can accommodate substrate movement without failure.
