tesa® ACX^plus 70740

3900µm double-sided acrylic foam tape

Product description

tesa® ACX^plus 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® ACX^plus 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.

Please note that we recommend using tesa® Adhesion Promoter as a surface pre-treatment. It leads to a significant improvement in adhesion levels, avoids moisture infiltration, and promotes long-term resistance against harsh environmental factors. Which tesa® Adhesion Promoter should be used depends on the substrates and the application. We will be glad to advise you in order to find the right solution.
