Product description

tesa® ACXplus 74712 Seal Line is a deep black acrylic foam tape for permanent mounting of seals, mainly on automotive clearcoat. 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® ACXplus 74712 Seal Line ensures a highly secure bond to the rubber profile, enables a higher application speed than using primer, and supports a more environmentally friendly production process.
By introducing a functional layer at the liner side, tesa® ACXplus 74712 can be used on various automotive clearcoats even without the use of adhesion promoters. The acrylic foam core ensures outstanding dimensional stability even at high temperatures and loads. At the same time, by its viscoelastic properties, tesa® ACXplus 74712 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 deep black color provides an enhanced appearance and high design flexibility.
