1. An Introduction to Pull-Off Adhesion on Coated Surfaces
When a coating is applied in the wrong climatic conditions, or to a poorly prepared surface; there is a much greater chance that the coating will blister, delaminate or simply not stick to the substrate.
To test how well a coating adheres to a surface, adhesion testers are used:
Elcometer offer three different pull-off adhesion testers. The original Elcometer 106, which is a hand operated mechanical gauge; the hydraulic Elcometer 506, with a separate, low height actuator and range of skirts for thick and thin substrates; and finally the Elcometer 510, which is similar in operation to the Elcometer 506 but, rather than manually, automatically applies the increasing force at a predefined and uniform rate, storing all of the results into memory by the simple press of a button.
