Self-Alignment Feature - Unequal pulling force during testing caused by uneven adhesive bond lines
Measures adhesion of coatings to metal, masonry and other substrates-revolutionary self-alignment feature brings new meaning to adhesion measurements
Self-Alignment Feature - Unequal pulling force during testing caused by uneven adhesive bond lines and coating surfaces can result in random, unexplainable readings. To obtain 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 Head enables even distribution of the pulling force over the surface being tested, preventing a one-sided pull-off.
Unique 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. The dolly¡¯s uniquely spherical articulating head is engaged into a ring of small ball bearings, ensuring correct self-alignment. This feature is found only on the PosiTest Adhesion Tester.
