Product description

tesa® ACXplus 74608 Seal Line is a deep black acrylic foam tape for permanent mounting of seals. 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 seals.
Compared to the conventional process with primer, tesa® ACXplus 74608 Seal Line ensures a highly secure bond to the rubber profile, enables a higher application speed than using primer, and improves the operational safety during the production process.
The acrylic foam core ensures outstanding dimensional stability even at high temperatures and loads. At the same time, by its viscoelastic properties, tesa® ACXplus 74608 Seal Line absorbs and dissipates dynamic and static loads. This also allows compensation of extreme physical stress caused by the different thermal elongation of bonded parts in rapidly changing temperatures.
The pressure sensitive adhesive side exhibits high adhesion values by itself but is also compatible with tesa adhesion promoters tesa® 60151 and tesa® 60153.
The deep black color provides an enhanced appearance and high design flexibility.
