Product description
tesa® ACXplus 70740 is a deep black double-sided acrylic foam tape. It consists of a high performance acrylic system and is identified by its bonding power, stress dissipation and its temperature and weather resistance.
Due to the product’s unique formulation, this double-sided pure acrylic foam tape combines a very good temperature and shear resistance with an outstanding cold shock resistance up to -40°. This product also shows robustness when it comes to outdoor performance. The viscoelastic core of this product is able to compensate for thermal elongations of bonded parts.
tesa® ACXplus 70740 is especially designed for permanent demanding outdoor bonding applications and is therefore suitable for exposure to extreme temperatures, UV, chemicals, salt water, as well as cleaning agents.
Main applications
The tesa® ACXplus product family is suitable for a wide range of constructive bonding applications. To ensure the highest performance possible, our aim is to fully understand the application (including the substrates involved) in order to provide the right product recommendation.
