Loop tack testing, as defined in АСТМ Д6195, evaluates the tackiness of pressure-sensitive adhesives by measuring the force required to remove an adhesive loop from a stainless steel substrate.

The test is conducted using either a tensile tester (Test Method A) or a loop tack tester (Test Method B), with controlled contact between the adhesive and substrate. This test is crucial for assessing adhesive performance in quality control and research applications.

Cell Instruments offers high-precision loop tack testers designed for compliance with ASTM D6195, ensuring reliable and repeatable tack measurements for various adhesive materials.
