tesa® ACX^plus 88308 Primerless Line

0.8 mm double-sided acrylic foam tape for mounting of automotive exterior attachment parts

Product description

tesa® ACX^plus 88308 is a double-sided acrylic foam tape for mounting of automotive exterior attachment parts. It is a triple-layer symmetrically designed product, coated on both sides 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 also has excellent adhesive properties when it comes to different types of OEM clear coats. Thanks to its viscoelastic acrylic foam core, tesa® ACX^plus 88308 Primerless Line has the ability to absorb and dissipate dynamic and static loads.
Also available in 0.5mm, 1.1 mm and 1.5 mm formats
