Material Notes:
3M™ Adhesion Promoter K520UV is a liquid primer used to improve the adhesion of 3M™ Acrylic Foam and Acrylic Plus Tapes to Polyolefin-based substrates such as thermoplastic olefins (TPO), Polypropylene (PP), and EPDM rubber. A fluorescent dye has been added so that the primer coverage can be verified. Since formulations and surface energies vary for these materials, each application should be verified through testing. 3M adhesion promoter K520UV is specifically formulated to be used with 3M Acrylic Foam and Acrylic Plus Tapes for automotive applicationsInformation provided by 3M
