Adhesion Test Tab and Method of assessing the cleanliness of a surface before adhesive bonding

In structural glazing bonding process production, it is critical to ensure that the surfaces of the substrates to be bonded are properly cleaned before bonding operations. It is herein described an adhesion test tab useful to perform quick check and ensure if the cleaning operation is properly performed prior tape application. It is further disclosed a method of assessing the cleanliness of a surface before adhesive bonding, using the adhesion test tab.

The intended use is to test a surface for sufficient cleanliness after a cleaning operation and prior an adhesive bonding operation. The adhesion test tab of the disclosure mainly consists out of two narrow stripes of single coated adhesive tapes, laminated on top of each other, as represented in Figure 1 below.

The lower stripe (2) has a typical low adhesion backing with a defined internal release strength which is adjusted to the necessary adhesion to the substrate (6) to be tested. Its adhesive side is covered with a silicon paper liner (3) for protection purpose which has to be removed before use. Both stripes have a non-sticky finger lift (4) and (5) to allow for an easy pick and peel off operation from the substrate to be tested. Finger lift (4) is used to peel the stripe (1) for adhesion test purpose. As for finger lift (5), it is used to completely remove the whole tab (corresponding to the combination of stri...
