Rubber Lining Adhesion Test

The standard is divided into.

Rubber lining adhesion test.

Method b 90 stripping test rubber part assembled to one metal plate. A standard method for the application and performance of this test is available in astm d6677. Note before applying adhesive to the lining the rubber may require to be freshened by giving it a wipe with solvent. The vehicle engine mounts rubber coated metal components and rubber lined tanks and containers use the astm d429 standard.

1 1 these test methods cover procedures for testing the static adhesional strength of rubber to rigid materials in most cases metals. For polymer rubber linings qualification of procedures may include adhesion testing. On metal substrates a more formal version of the knife test is the tape test. The testing procedures include peel strength or tensile strength of the adhesion edge.

There are many conditions that can affect the adhesion of rubber to various substrates such as metal and fabrics. To read more about astm d413 astm d378 and the equipment req. Relevant adhesion test results obtained during the last two projects performed by the lining applicator may be referred to in. Method e of astm d429 determines the adhesive strength of rubber tank lining to a tank wall using a 90 degree strip test.

Pull off adhesion testing is widely used to assess the protective coating process and to determine if a coating is fit for service in new construction and for repairs to existing structures. 3 4 just prior to the application of the rubber repeat above step 3 3 using tack on substrate then apply tack on rubber lining. This test peels rubber conveyor belting and measures the average peel force over a 5 section. Chapter rubber compound and vulcanizate testing is related to the chapter on rubber raw material testing and provides a comprehensive description of the system of testing rubber compounds materials and vulcanizates starting from sampling and testing vessels up to evaluation of test results according to specific standards.

Method c measuring adhesion of rubber to metal with a conical specimen. Pressure sensitive tape is applied and removed over cuts made in the coating. Either the rubber material fails internally or at the adhesion surface to the metal. There is no known correlation to other adhesion test methods pull off tape etc.

The result is often critical to the acceptance or rejection of a coating process as the adhesion value quoted by. Allow to dry until tacky on both the substrate and the rubber approximate 1 hour. The astm d429 includes the test procedure to determine the adhesion of rubber to rigid metal substrates. Once the test is complete you will want to record the force vs displacement.
