Custom-fit
This test method differs from FTM 1 in that it can allow the end user to compare the repositionability of different laminates. Measuring peel adhesion at 90° normally gives a lower value than at 180° and allows values to be measured for materials normally giving paper tear.
Peel adhesion is defined as the force required to remove pressure sensitive coated material, which has been applied to a standard test plate under specified conditions, from the plate at a specified angle and speed. Adhesion is measured 20 minutes and 24 hours after application, the latter being considered as the ultimate adhesion.
