The pull-off adhesion strength and mode of failure of a coating from a concrete substrate are important performance properties.
The pull-off adhesion test determines the maximum perpendicular force that a surface area can bear before a temporarily stuck plug of material is detached.
Note This test method is a destructive test and spot repairs are required.
The portable pull-off testers are capable of applying a concentric load and counter load to a single surface so that coatings can be tested even though only one side is accessible.
LMATS can perform this test in accordance with ASTM D7234.
Our digital testing instrument can test upto 20MPa using a 20mm dolly on types of concrete coatings.
LMATS provides concrete testing services from our Melbourne, Sydney, Albury, Newcastle, Brisbane and Perth laboratories. Contact one of LMATS laboratories near to your location for further information.
