Scientific Assistance
Even the best products can use a bit of assistance on occasion, and that’s the idea behind our 3M™ Adhesion Promoter K520UV. It’s designed to help our 3M™ Acrylic Foam and Acrylic Plus Tapes adhere to substrates which are typically difficult to form an adhesive bond against. This includes surfaces to Polyolefin-based substrates such as thermoplastic olefins (TPO), Polypropylene (PP) and EPDM rubber. This acetone solvent dries fast to maximize work time and eliminate downtime. It contains a fluorescent dye that makes it easily visible once applied, and helps technicians to quickly verify that coverage is complete and consistent for a reliable bond. Since formulations and surface energies vary for these materials, each application should be verified through testing.
Better Science for Better Adhesion from 3M
Since 1925 when a 3M lab assistant invented masking tape, 3M has been applying science to life –developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations and all of it goes into each 3M product developed for automotive OEM, like 3M™ Adhesion Promoter K520UV.
