An optimised adhesive layer ensures an easy-to-apply, bubble free application of the Vikuiti™ screen protector DQC160.

The adhesive layer is only slightly adhesive and readily forms a film over even surfaces. The protective film can easily be removed or repositioned at any time. Th This part is cataloged in the U.S.
