TESA ACXplus 7074 High Resistance, double-sided acrylic foam tape 1000 µm, black, 25 m × 12 mm, for outdoor assemblies and profiles
0
Description
TESA ACXplus 7074 High Resistance is a black, double-sided acrylic foam tape, 1000 µm thick, in a 25 m × 12 mm size. The 707x series is designed for durable indoor and outdoor assemblies, including joints between materials with different coefficients of thermal expansion. Its viscoelastic core compensates thermal stress across −20…80 °C, and the tape offers high temperature and thermal-shock resistance.
Benefits and unique features
- Temperature resistance: 120 °C (long-term) / 220 °C (short-term)
- Exceptional thermal-shock resistance down to −40 °C
- Effective CTE compensation across −20…80 °C
- Durable bonds for indoor and outdoor use
- Adhesion can be boosted with a suitable tesa adhesion promoter
Properties and applications
- Reinforcement and mounting profiles: reliable bonding and vibration damping (joinery, transport, appliances, elevators).
- Invisible glass-to-metal bonding: clean, aesthetic joints for interior fit-out.
- Wall housings and panels: flexible joints for outdoor applications.
- Structural glass bonding: long-lasting, stable bonds.

Storage recommendations
Store in a clean, dry and cool place away from UV and heat sources, in the original packaging. Clean and degrease substrates before application; for outdoor and demanding uses, apply a suitable tesa adhesion promoter and perform a bond test.
FAQ
1) What is the tape thickness?
1000 µm (1 mm) acrylic foam.
2) Is it suitable for outdoor use?
Yes — the 707x line is intended for durable indoor/outdoor assemblies; an adhesion promoter is recommended.
3) What temperature limits?
120 °C long-term and 220 °C short-term; thermal-shock resistance down to −40 °C.
4) What adhesion to steel does 7074 reach?
About 16 N/cm initially, ~32 N/cm after 3 days and ~33 N/cm after 14 days.
5) How does it perform on PP?
Low adhesion (~1 N/cm even after 14 days) — testing and a suitable promoter are required.
