74512 Seal Line
Heat-activatable acrylic foam tape
Product Features
- Outstanding dynamic T-block performance
- Superior dynamic shear resistance
- PFAS / PFOS free Product
Product description
tesa® ACXplus 74512 Seal Line is a deep black acrylic foam tape for permanent mounting of door seals, sun roof seals and Obstacle Detection System (ODS) profiles. 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 74512 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.
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® ACXplus 74512 Seal Line absorbs and dissipates dynamic and static loads optimally. This exceptional capability enables tesa® ACXplus 74512 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.
The density of the acrylic foam is 800 kg/m³.
