tesa® ACXplus 7811 Black Line

1.1mm double-sided acrylic foam tape for mounting automotive exterior trims and parts

Product description

tesa® ACXplus 7811 Black Line is a deep black double-sided acrylic foam tape for mounting automotive exterior trims and parts. It provides high bonding power on MSE clear coats and plastics like ABS and chromed ABS, and performs outstandingly on PC and PMMA. Its impressive cold shock resistance is based on a modified acrylic foam core, which assures a reliable bond even at extreme low temperatures.
Being viscoelastic, tesa® ACXplus 7811 Black Line optimally absorbs and dissipates dynamic and static loads. This exceptional capability enables tesa® ACXplus 7811 Black Line to compensate for extreme physical stress caused by different thermal elongation of bonded parts in changing temperature conditions.
Also available in 0.5 mm, 0.8 mm, 1.2 mm, and 1.5 mm formats.
Main features:
  • Deep black color for enhanced appearance and design flexibility
  • Excellent cold shock performance
  • High humidity and UV resistance
  • Closed cell acrylic foam core
  • Viscoelastic acrylic foam core to compensate for thermal elongation differences of bonded parts
