PRODUCT OVERVIEW

503341: SWITCH,PRESSURE.

Crystal-clear, hard-coated, dirt-repellent, very simple assembly, residue-free removal The 3M Vikuiti™ screen protector DQC160 is designed for application on electronic screens and offers reliable protection from scratches and soiling. The surface of the film is as smooth and shiny as glass. Adhesive and film are both crystal clear so that when applied the film appears transparent.

The hard coating of the Vikuiti™ screen protector DQC160 furthermore offers optimal mechanical protection from scratches. An additional non-adhesive layer ensures that the protective film is also dirt-repellent enabling the removal of ball-point pens and marker pens ink through dry wiping. 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.
