24 hours under water, 96 hours at 35° C, another 8 hours at –35° C, 120 days of storage at 155° C – those are the requirements, for example, that our high performance tape must satisfy. These adhesive tape tests are repeated several times – before being followed by another dynamic sheer test and another 7 days of storage at 60° C. The extremely high tack of the adhesive tape passed all the tests.
Things got even hotter for tesa® ACXplus in the Society for Materials Research and Testing Institute for the Construction Industry [Gesellschaft für Materialforschung und Prüfungsanstalt für das Bauwesen ] laboratory, Leipzig. Lightweight panels made of aluminium, which had been bonded with tesa® ACXplus 7078, were set on fire in the fire test. The tesa tape withstood the flames exceptionally well in the component test and was certified in fire safety class "C – s2, d0." This means that it can hardly be ignited; smoke hardly develops; and flammable material does not drip down.
