| Self-Aligning Unequal pulling force during testing caused by uneven adhesive bond lines and coating surfaces can result in random, unexplainable readings. To obtain more repeatable and meaningful adhesion measurements, it is imperative that the pulling force applied to the test dolly is uniformly distributed over the surface being tested.The Self-Aligning Dolly enables uniform distribution of the pulling force over the surface being tested, preventing a one-sided pull-off. Test Dollies: The PosiTest Adhesion Tester uses inexpensive single-use aluminum dollies designed according to internationally accepted standards and practices. They have a full 20 or 50 mm surface diameter with no holes to clean or keep from filling with adhesive. |
