tesa® ACXplus 77708 – Primerless LSE Bonding Tape for Automotive Applications

Introducing tesa® ACXplus 77708, a high-performance double-sided acrylic foam tape engineered for primerless bonding of low surface energy (LSE) plastics. This 0.8 mm thick tape offers exceptional adhesion to materials like polypropylene (PP) and PP/EPDM, eliminating the need for primers in automotive exterior applications.

The unique asymmetrical double-layer design of tesa® ACXplus 77708 features a specialized LSE adhesive on the open side, ensuring efficient and secure bonds to typical automotive attachment parts. Its viscoelastic acrylic foam core compensates for different thermal elongations of bonded parts, providing excellent bonding stability across a wide temperature range. Additionally, this tape exhibits outstanding wet-out properties, high humidity, and UV resistance, making it ideal for various automotive applications.
