GD751S45-229 test fixture meets ASTM D751 Sec45 requirements. This test determines the adhesion of the coating to the fabric. The peel adhesion of coating to fabric test in ASTM D751 requires two sets of two specimens each for the longitudinal and transverse direction. Your specimens should be rectangular and sized as 25 mm (0.98 in) wide x 200 mm (7.87 in) long. After creating the specimens, separate the coating from the backing for a distance of 50 mm (1.9 in).

First clamp the separated portions of your sample in the jaws so that movement of the test machine will separate the coating from the backing. Next run the test machine so that it separates the coating from the backing with a uniform speed of 0.85 mm/sec (0.03 in) or 5 mm/sec (0.19 in) for a minimum of 76 mm (3 in). Record the force necessary to separate the coating from the backing. Adhesion of coating shall be the average of the 5 highest peak loads during the test.
