tesa^® ACX^plus 74508 Seal Line is a deep black acrylic foam tape for permanent mounting of weather strips and water box seals, mainly on automotive glass. It has a heat-activatable adhesive on the non-liner side. The adhesive gets activated by hot air or near-infrared when applying it onto the PP/EPDM, PP, TPV, or TPE seal.

Compared to the conventional process with primer, tesa^® ACX^plus 74508 Seal Line ensures a highly secure bond to the rubber profile, enables a higher application speed than using primer, and realizes a more environmentally friendly production process.

Its outstanding cold shock resistance is based on a modified acrylic foam core, which assures a reliable bond even at extreme low temperatures. Being viscoelastic, tesa^® ACX^plus 74508 Seal Line absorbs and dissipates dynamic and static loads optimally. This exceptional capability enables tesa^® ACX^plus 74508 Seal Line to compensate for extreme physical stress caused by the different thermal elongation of bonded parts in rapidly changing temperatures.

The deep black color provides an enhanced appearance and high design flexibility.
