is designed to test the adhesion of the coating material on the base fabric by bending and folding, that is, the mechanical stability of the coating. The design is based on the Chrysler laboratory test method LP-463LB-9-01. This test characterizes the adhesion of the coating material on the base cloth of vinyl-coated fabric and leather. It can also test vinyl coated fabrics, leather, unsupported vinyl and other soft decorative materials for cracking, bleaching, cracking, and layer separation.
fulfill the standard:
Chrysler LP-463LB-9-01, Chrysler LP-463KB-113-01, Chrysler LP-463KB-10-01
product details:
The tester can test 4 samples at one time, including 3 bending samples and 1 folded sample. When the bending test specimen is clamped by the clamp at both ends and tightened, one end is kept fixed and the other end is moved horizontally, and the bending test can be carried out. Clamp both ends of the folded specimen close to two opposite flat plates, and apply a 12 lb load on the folded area. The corresponding pressure can be applied by closing the plate.
The bent specimen is tightened with a fixed weight. The tension must be controlled.
