Product information

tesa® ACXplus 77815 Primerless Line

1.5 mm double-sided acrylic foam tape



Product description

tesa® ACXplus 77815 is a double-sided acrylic foam tape for automotive exterior attachment part mounting. It is a triple-layer symmetrically designed product, coated on both sides with LSE adhesive.

tesa® ACXplus 77815 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 77815 Primerless Line has the ability to absorb and dissipate dynamic and static loads.

Features:

  • High initial performance on LSE plastics and difficult-to-bond OEM clear coats
  • Excellent bonding stability at wider range of temperatures
  • Reaches high peel-adhesion level right after application
  • Superior peel adhesion on PP substrates, even at an application temperature as low as 5°C
  • Viscoelastic acrylic foam core to compensate for different thermal elongation of bonded parts
  • Outstanding wet-out property
  • High humidity and UV resistance


Benefits:

  • Eliminates the primer in the production process
  • Enables a much more efficient and robust application
  • Reduces the total process cost
  • Realizes healthier working conditions

1  Achieves a more environmentally friendly production
