ASTM D4145 standard now offered at Micom Laboratories

Micom laboratories is pleased to announce that it now offers the ASTM D4145 standard as part of its coating testing services. This method details a procedure which allows to assess the flexibility and the adhesive strength of a coating by the means of a T-bend test. More particularly, this test protocol relies on the use of a low magnification tool and of a pressure-sensitive tape in order to characterize those attributes. Moreover, this current practice may be coupled with a UV test, a salt spray test or an accelerated aging test as a means to evaluate the evolution of those properties.

ASTM D4145 test

The goal of ASTM D4145 is to employ a T-bend test as a means to assess the ability of a coating system of a metal sheet to withstand deformation strain that may occur in the manufacturing process of the latter. In fact, a T-bend test consists of evaluating the flexibility and adhesion of the coating through the use of a pressure-sensitive tape and of a low magnification tool as a means to identify the presence of cracks and pickoff at the surface of the bent metal foil
