tesa® 4914 Low VOC

250µm double-sided non-woven tape with tackified acrylic adhesive and differential adhesion level for a wide range of rough materials



Product description

tesa® 4914 is a 250 µm translucent double-sided self-adhesive tape consisting of a non-woven backing and a tackified acrylic adhesive.
This tape is characterized by its differential adhesion properties for an excellent bonding strength on a wide range of materials, particularly very rough surfaces. Compared to the open side, the covered side is foamed, has a higher coating weight, and therefore offers a higher adhesion.
tesa® 4914 has been designed for an excellent performance on rough surfaces like leather and textiles, plaster and stone, or other rough materials.

Main features

  • Differential bonding strength
  • Very good performance on rough surfaces
  • High initial tack
  • Superior adhesion level on covered side
  • Lower adhesion level on open side
  • Low VOC (according to GB 27630) – no critical substances detectable
  • Flame retardant (according to FAR/JAR/CS 25.853(a) Appendix F part I (a)(1)(ii))
  • Suitable for dispenser



Main applications

tesa®  4914 is suitable for various types of mounting applications. To ensure the highest performance possible, our aim is to fully understand your application (including the substrates involved) in order to provide the right product recommendation.
Example applications are:

  • Mounting car roof linings in car production
  • Mounting cables and wire harnesses to headliners for automotive interiors
  • Mounting leather and textiles as sewing support
  • Laminating foamed materials in combination with smooth materials on the open side
