ASTM D4541 test now offered at Micom Laboratories

Micom Laboratories is delighted to announce that it now offers the ASTM D4541 test as part of its offering for coating testing services . This standard details two procedures that allow to evaluate the adhesion capacity of a coating system on a metal surface through the use of an adhesion tester. Moreover, the present test protocol can characterize the pull-off strength of coatings of rigid substrates such as: plastics and wood, but it cannot be employed to assess concrete. Indeed, it is necessary to use ASTM D7234 in order to evaluate the latter. Lastly, subsequent to an accelerated aging test, this method may be used as a means to determine the evolution of the adhesion of a coating over time.

ASTM D4541 test

The goal of ASTM D4541 is to assess the pull-off strength of the sample by providing the guidelines for the preparation, the testing and the evaluation of the results of the coated systems. Indeed, it is through two tests protocols that it is possible to appraise the adhesion of the coated specimen. On the one hand, protocol 1 is employed to study the maximum load that can be applied to an area before the loading fixture is detached of the sample or when it reaches the limit of the apparatus. On the other hand, protocol 2 is used to ascertain the integrity of the coated specimen until it meets the minimum load criterion. Regardless of the protocol employed, the principle of this method is to determine the performance of binding between the coating system and the metal substrate by pulling it with an instrument. More specifically, it is by monitoring and gradually increasing the force, that is applied by the test apparatus, on the loading fixture that it is possible to characterize this property.

Micom offers polymer testing services for a wide selection of material and products. For more information about the ASTM D4541 test, we invite you to contact our material testing laboratory today. It will be our pleasure to answer your questions about either of those tests.

Micom Laboratories is a third party industrial material testing laboratory accredited by the Standards Council of Canada, CGSB, ISTA and many other organizations.
