Proven performance for window seals that stand the test of time

See how tesa® 73604 performs in the peel adhesion test.

Bar chart shows adhesion strength (N/cm) for tesa tape on glass; all values exceed 12 N/cm with 100% cohesive failure in each test.

tesa® 736xx passed the critical customer spec of 180° peel test with real substrate, showing a 100% cohesion failure under all conditions. Cohesion failure mode shows that the anchorage of the tape to both substrates is very reliable.

Innovation tailored for customer needs
An OES supplying waterboxes to a large German automotive manufacturer was working with a range of standard-sized adhesive tapes. The problem was that a new seal design required a tape of special dimensions.

Their adhesive supplier couldn’t create the unique product they needed, so they asked tesa.We worked closely with our customer, and with their customers up and down the value chain, to develop a rigorously tested tape of the right dimensions that could still fulfil temperature and shock resistance and peel test requirements.

And we maintain that relationship today, to give our customer confidence they have our support as their products reach the OEM and then onto roads around the world.
