TESA ACXplus 7074 High Resistance, double-sided acrylic foam tape 1000 µm, black, 25 m × 25 mm, for profiles, glass–metal, outdoor use
0
Description
TESA ACXplus 7074 High Resistance is a black, double-sided acrylic foam tape with a 1000 µm thickness in a 25 m × 25 mm size. The 707x series is designed for durable indoor and outdoor assemblies, including joints between materials with different thermal expansion. Its viscoelastic core compensates thermal stresses across −20…80 °C and the tape features high temperature and thermal-shock resistance.
Benefits and unique features
- Thick 1 mm acrylic foam — strong bonding and vibration damping
- 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
- Outdoor durability — weather-resistant bonds
- Adhesion can be boosted with tesa adhesion promoters
Properties and applications
- Reinforcement / stiffening profiles: durable bonding and vibration damping in joinery, transport, appliances and elevators.
- Mounting profiles: fast, clean installation without drilling.
- Invisible glass-to-metal bonding: clean, aesthetic interior finishes.
- Wall housings, panels, structural glass bonding: long-lasting joints exposed to the elements.
- Application tip: on demanding substrates, use a suitable tesa adhesion promoter and run a bond test.

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 bonding 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.
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 an appropriate promoter are required.
