Pull-Off Adhesion Tester | Elcometer 106

The Elcometer 106 Pull-off Adhesion Tester is easy, fully portable and provides a numerical value for adhesion

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. There are essentially 3 coating adhesion test methods available to the coating inspector: – cross hatch; such as the Elcometer 107 or 1542, where a cutter with 6 or 11 blades is used to cut two sets of lines at right angles – the resultant debris is removed using either adhesive tape, a brush, or compressed air, and the results determined by the use of tables; – push off adhesion testers; such as the Elcometer 108 and 508, have a pin which goes through the centre of a dolly that has been glued to the coated substrate, and pushes it off the coating, with the force recorded – ideal for convex and concave surfaces; – and the most commonly used method, the pull-off adhesion test, where a dolly is adhered to the coated substrate, pulled off, and the resultant force recorded.

Elcometer 106 is ideal for: paint or plasma spray on bridge decking, coatings on steel, aluminum, concrete, etc.

Test Method

An adhesion testing dolly is bonded to the coating using an adhesive. The Elcometer 106 adhesion tester houses a spring arrangement that applies a lift force to the dolly as the tension is increased. When the coating is pulled off the surface, an indicator on the scale shows the numerical value of adhesion expressed in terms of the force per unit area required to remove the dolly. Inspection of the dolly face is required to determine the failure mode. To increase sensitivity at low values or for uneven surfaces, a 40mm (1.52″) dolly is available. When using the 40mm (1.52″) dolly, divide the scale reading by 4.
