ASTM D6195

Test Materials: The ASTM D6195 Loop Tack test is designed for evaluating the initial adhesion of pressure-sensitive adhesives. The primary materials involved include the adhesive-coated substrate (usually a tape or film) and a test surface, typically a flat, smooth, clean metal or plastic.
Test Process: The process involves creating a loop with the adhesive-coated substrate and then pressing it against the test surface. After a specified dwell time, the loop is pulled apart at a consistent rate, and the force required to detach the adhesive is measured.
Test Result Interpretation: Results are interpreted by assessing the peak tack force, typically recorded in grams or Newtons. Higher values indicate stronger initial adhesion, while lower values suggest weaker adhesion. This data helps determine adhesive suitability for various applications.
