Paint film bending strength Tester

The paint film bending strength tester uses the three-point bending method to place a coated substrate sample between two support points and applies a load at the center until the paint film cracks, measuring its bending strength and flexibility. It is used to evaluate the resistance to bending and cracking of coatings, such as paints and electrophoretic coatings, during processing or use, ensuring the adhesion and durability of the coating.
Selection
When selecting a paint film bending strength tester, consider compliance with testing standards such as ISO 1519 or ASTM D522; the load range should cover sample requirements; fixtures should accommodate substrates of varying thicknesses; the device's accuracy must meet error control standards; the operation interface should be user-friendly, and data output must be stable and reliable.
