tesa® 77711 Primerless Line
1.1 mm double-sided acrylic foam tape
Product Features
- ▪ High initial performance on LSE plastics
- ▪ Excellent bonding stability at a wider range of temperatures
- ▪ Reaches high peel-adhesion level right after application
Product description
tesa® ACXplus 77711 is a double-sided acrylic foam tape for automotive exterior attachment part mounting. It is an unique double-layer asymmetrically designed product, coated on one side with LSE adhesive.
tesa® ACXplus 77711 can help you eliminate the primer in your 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 also has excellent adhesive properties when it comes to easy-to-bond OEM clear coats. (LSE: low surface energy; MSE: medium surface energy) Thanks to its viscoelastic acrylic foam core, tesa® ACXplus 77711 Primerless Line has the ability to absorb and dissipate dynamic and static loads.
0.8 mm and 1.5 mm thicknesses are available
