Vorrichtung zur Haftfestigkeitspruefung von Beschichtungen

DE 202006009617 U1 UPAB: 20070102 NOVELTY - The device has a fixedly arranged sample holder (9) for accommodation of a sample (1), and a movable slide (6), which is lockable. The slide is connectable with a separating device in such a manner that the separating device exerts a tear-off force on an adhesive tape attached on the sample with releasing the lock of the slide. The slide has springs that are downwardly accelerated in the vertical direction for increasing the force. USE - Used in a tape test for testing adhesiveness of a coatings e.g. optical coating such as optical metal oxide coating, on a polymer substrate. ADVANTAGE - The utilization of the fixedly arranged sample holder ensures that the tear-off force is not varied. The slide is connectable with the separating device in such a manner that the separating device exerts the tear-off force on the adhesive tape attached on the sample with releasing the lock of the slide, thus eliminating the subjective influence of the user in the tape test
