tesa® ACXplus 77708 Primerless Line
Primerless Acrylic foam tape
Product description
tesa® ACXplus 77708 is a 0.8mm acrylic foam tape with an unique double-layer asymmetrically designed product, coated on open side with LSE adhesive. It can help eliminate the primer in the process. Its high-performance LSE adhesive creates an efficient and secure bond to typical automotive attachment parts made of LSE (like PP and PP/EPDM) and MSE (like ABS) plastics without primer.
In addition, our product has excellent adhesive properties when it comes to easy-to-bond OEM clear coats. Thanks to its viscoelastic acrylic foam core, tesa® ACXplus 77708 has the ability to absorb and dissipate dynamic and static loads.
Also available in 1.1 mm and 1.5 mm thicknesses.
Main features
- High performance on LSE plastics without primer
- Superior peel adhesion on PP substrates even at an application temperature as low as 5°C
- Excellent bonding level right after application
- Excellent bonding stability at a wider range of temperatures
- Efficient and robust application
- Viscoelastic acrylic foam core to compensate for different thermal elongation of bonded parts
- Outstanding wet-out property
- High humidity and UV resistance
LSE: low surface energy
MSE: medium surface energy
