3M™ Adhesion Promoter 4298UV is a liquid primer used to improve the adhesion of 3M™ Acrylic Foam Tapes.
3M™ Adhesion Promoter 4298UV is a liquid primer used to improve the adhesion of 3M™ Acrylic Foam Tapes to low surface energy plastics such as thermoplastic olefins (TPO), thermoplastic urethanes (TPU), and polypropylene. A fluorescent dye has been added so that primer coverage can be verified. Since formulations vary for these materials, each application should be verified through testing. Apply promoter only to areas that will be fully covered with tape. The primer should be dry before applying tape. For best results, apply tape immediately after primer application or no more than one hour after primer applications. Be sure the primed surface remains free from contaminants prior to tape application.
