Description

ASTM D5179 -Standard Test Method for Measuring Adhesion of Organic Coatings in the Laboratory by Direct Tensile Method

 

ASTM D5179 -Adhesion of Organic Coatings in the Laboratory by Direct Tensile Method

ASTM D5179 – This test method covers the laboratory determination of organic coating adhesion to plastic substrates by mounting and removing a metal stud

from the surface of the coating and measuring the force required to break the coating/substrate bond with a tensile tester.

This test method may also be applied to substrates other than plastic.

This test method requires that the metal stud be adhered directly to the surface of a coated, cured panel

This test method is used to compare the adhesion of coatings to plastic or other substrates, thus allowing for a quantitative comparison of various coating/substrate

combinations in laboratory conditions.

Other tensile test methods are Test Methods D4541D7234D7522, and ISO 4624 (but are not technically equivalent).


Significance and Use

The pull-off strength (commonly referred to as adhesion) of a coating is an important performance property that has been used in specifications.

This test method serves as a means for uniformly preparing and testing organic coatings on plastic or other substrates.4 Further information may be found in

Appendix X1.

*** Before conducting ASTM D5179  , it is important to read the entire specification in the relevant ASTM  publication.
