Primer and adhesion promoters

Adhesion primers (or adhesion promoters) are liquid treatments specially formulated to prepare surfaces for superior tape bonding. Applied before the tape, they enhance the surface energy of challenging substrates and improve the strength and durability of the adhesive bond.

Available Types
This category includes a variety of primers: universal primers for plastic, metal or glass; specialized primers for low-surface-energy (LSE) materials such as polypropylene (PP) or polyethylene (PE); fast-drying formulations; fluorescent-dye primers for coverage inspection; high-temperature primers; and promoters tailored for acrylic or polyurethane adhesives. For instance, 3M Adhesion Promoter 86A is designed for polyurethane-painted or epoxy-composite surfaces to boost initial adhesion.

Why choose Tapes Store
Choosing the right adhesion primer at Tapes Store ensures more reliable bonding on challenging substrates, such as LSE plastics or coated surfaces. Our technical team helps you select the ideal promoter based on your tape type, substrate material, and operating conditions. The correct primer reduces the risk of tape delamination, guarantees long-term bond performance, and improves assembly quality in industrial or structural applications.
