tesa® 77811 Primerless Line
1.1 mm double-sided acrylic foam tape for mounting of automotive exterior attachment part
Product Features
- Features:
- ▪ High initial performance on LSE plastics and difficult-to-bond OEM clear coats
- ▪ Excellent bonding stability at a wider range of temperatures
Product description
tesa® ACXplus 77811 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 different types of OEM clear coats. (LSE: low surface energy; MSE: medium surface energy). Thanks to its viscoelastic acrylic foam core, tesa® ACXplus 77811 Primerless Line has the ability to absorb and dissipate dynamic and static loads
0.5, 0.8 mm and 1.5 mm thicknesses are available
