Product Details

Model: LT-500

Standards: GB/T 5210, ASTM D4541/D7234,ISO 4624/16276-1

 

This digital pull off adhesion tester can be used to test the adhesive strength of the coatings on different substrates, the strength is indicated in Mpa or psi, hydraulic loading, manual operation, digital display, test data can be exported out with a USB port. 

 

Test method (ASTM D4541)

The pull-off test is performed by securing a loading fixture(dolly,stud) normal to the surface of the coating with an adhesive, after the adhesive is cured, attach the tester to the loading fixture and let it aligned then apply a tension normal to the surface, then loading the force applied to the loading fixture slowly till there is a plug of material is detached, the pull off strength is computed based on the maximum indicated force on the screen, the test may be destructive.
