Product information

tesa® 4957

Product description

tesa® 4957 is a double-sided PE-foam tape for general mounting applications. It consists of a highly conformable PE-foam backing and a tackified acrylic adhesive. tesa® 4957 has been externally certified for window bar mounting.

Product benefits:
  • Versatile adhesive for high immediate adhesion on numerous substrates
  • Fully outdoor suitable: UV, water and ageing resistant
  • Compensates for differing thermal expansion of dissimilar materials
  • High immediate bonding strength even at low bonding pressure
  • Very good cold shock absorbtion

Main applications

  • POS displays, exhibition sample displays
  • Shelf edge labels
  • Cable channels, window bars, window skirting trims
  • Decorative glass or mirror elements on furniture
  • Solar module frames
