Pull-off Test

Adhesion of a single coating or a multi-coat system of paint, varnish or related products is assessed by measuring the minimum tensile stress necessary to detach or rupture the coating in a direction perpendicular to the substrate. This method maximizes tensile stress as compared to the shear stress applied by other methods such as scratch adhesion and their results may not be comparable. The test is performed by securing a loading fixture (dolly) perpendicular to the surface of the coating with an adhesive. After the adhesive is cured, a testing apparatus is attached to the loading fixture and aligned to apply tension perpendicular to the testsurface. The force applied is gradually increased and monitored until either a plug of coating material is detached, or a specified value is reached.

The CB-15500 digital pull-off adhesion tester is a portable, hand-operated instrument which is used to measure the force required to pull a specified test diameter of coating away from its substrate using hydraulic pressure. The pressure is displayed on a digital LCD and represents the coating’s strength of adhesion to the substrate.

It evaluates the adhesion (pull-off strength) of a coating by determining the greatest tensile pull-off force that it can bear before detaching. Breaking points, demonstrated by fractured surfaces, occur along the weakest plane within the system consisting of dolly, adhesive, coating layers and substrate.

Test Principle

Coating or a multi-coat system of paint is applied/distributed to substrate uniformly with a certain thickness.

After the coating has dried or cured, adhere the dolly to the surface of the coating directly with a special adhesive.

After the adhesive is cured, use the Imbotec Miza CB-15500 digital pull-off adhesion tester to attach the loading fixture and align it to apply tension perpendicular to the test surface. The tester will pull off the dolly at a speed of 1MPa/s per hydraulic pump, and will measure the force required to pull the specified test diameter of coating away from its substrate using hydraulic pressure, this force is shown on the LCD display.
