Dolly adhesion test
Dolly adhesion test This test is used to measure the adhesive strength (bonding strength) of a coating, paint, or lining to its substrate (like metal, concrete, or other surfaces).

Destructive Test – Dolly Pull-off Adhesion Test: The Dolly Pull-off Adhesion Test is a destructive testing method used to determine the adhesive strength between a coating and its substrate. In this test, a metal dolly is bonded to the coated surface using a strong adhesive. After the adhesive cures, a mechanical or hydraulic device applies a perpendicular pulling force until the coating separates. The maximum force required to detach the dolly from the surface indicates the adhesion strength of the coating. Since this test damages the coating at the test point, it is classified as a destructive test.
Non-Destructive Test – DFT (Dry Film Thickness) Test: The Dry Film Thickness (DFT) Test is a non-destructive testing method used to measure the thickness of a coating or paint layer applied on a surface without damaging it. This test ensures that the coating has been applied to the specified thickness, which is essential for proper protection and performance.
Non-Destructive Test – DFT (Dry Film Thickness) Test: The DFT Test is a non-destructive testing method used to measure the thickness of a dry coating layer applied on a surface, without causing any damage to the coating or substrate.
