Product information

tesa® 4965 Differential

165µm double sided transparent asymmetrical filmic tape



Product description

tesa® 51865 is an asymmetrical transparent double-sided self-adhesive tape consisting of a PET backing and a tackyfied acrylic adhesive.
The covered side of tesa® 51865 has a high coating weight for maximum flexibility and versatility on multiple surface demands. The open side of tesa® 51865 shows a reduced coating weight that guarantees a secure bond to flat profiles laminated under controlled conditions.

tesa® 51865 features especially:
  • Excellent bond to extruded trims and profiles
  • Reliable bond even to LSE ( Low Surface Energy)  substrates
  • Immediate usability right after assembly
  • Suitability for most demanding applications such as heavy stress, high temperatures or critical substrates

Main applications

  • Mounting of decorative trims and profiles in the furniture industry
  • Lamination of magnetic stripes
  • Roller blind production
  • Equipping extruded plastic profiles with transparent double sided filmic tape
