An essential aspect of protective coatings is how well they adhere to the substrate to which they are applied.
The determination of adhesive strength of a coating to its substrate can be conducted by the peel adhesion resistance test using a constant rate of force provided by a tensile machine or a hanging mass test set up. Peel adhesion testing by a constant rate gives a quantitative value for the peel force required to peel the coating sleeve. An important factor in this test is assessment of the mode of failure, which helps determine the weakest adhesion point within the coating system.
Peel Adhesion testing in progress
