ASTM D3167 Floating Roller Peel Resistance of Adhesives

Scope:

The ASTM D3167 test technique covers the determination of adhesives’ metal-to-metal peel strength via a method that provides good reproducibility at low and high strength levels while also allowing for a simple test specimen preparation and testing approach.

Because they are being pushed apart across a one-inch axle, this floating roller peel test allows a flexible substrate to be softly peeled apart from a stiff substance. A specifically built floating roller peel setup is used for this test. Because of the effective angle of separation, the test works well for substrates that are less flexible and cannot be bent to a 90 degree or 180-degree angle.

Test procedure:

The unbonded end of the flexible adhesive is bonded perpendicular to the stiff substance and clamped into the grips according to ASTM D3167. The adhesive specimen is put between the two floating roller fixtures, and the load is applied as required. According to the testing standard, the test is carried out at a displacement rate. When the specimen ruptures or breaks, the test gets over. The test is carried out on at least five additional specimens.

Specimen size:

For the ASTM D3167 test technique, laminated test panels consisting of two adherends that have been appropriately prepared and glued together are used as the test specimens.

Data:

Average peeling load is reported in pounds-force per inch (or kilonewtons per meter). Variation in thickness of the adherends will generally influence the test values.
