tesa® 68614 double sided non-woven tape(roll)

tesa 68614 is a translucent, double-sided self-adhesive tape consisting of a non-woven backing coated on both sides with a tackified acrylic adhesive. Designed for reliable bonding in general-purpose mounting and assembly applications, tesa 68614 delivers high bonding strength on a variety of substrates combined with good temperature resistance.

Key Features

tesa 68614's non-woven backing provides flexible, conformable bonding performance, while its acrylic adhesive system delivers strong initial adhesion to steel and other common substrates, with adhesion strength that continues to build over the first two weeks after application. The tape offers good chemical resistance, good fogging performance (important for enclosed or automotive interior applications), and good ageing resistance against UV exposure — making it suitable for both general industrial assembly and longer-term mounting applications.

Performance Data

tesa 68614 delivers initial adhesion to steel of approximately 6 N/cm, increasing to approximately 10 N/cm after 14 days as the acrylic adhesive system fully develops its bond. The tape offers short-term temperature resistance up to 150°C and long-term temperature resistance up to 70°C, with very good static shear resistance at room temperature (23°C) and good static shear resistance at elevated temperatures (70°C) — important properties for mounting applications subject to sustained mechanical load.

Applications

tesa 68614 double-sided non-woven tape is used for fixing cardboard and paper bags, sealing envelopes and shipping bags, securing miscellaneous goods and decorations, and general mounting and assembly applications across packaging and light industrial use cases. Its balanced combination of bonding strength, temperature resistance, and flexibility makes it a versatile general-purpose choice for converters and assembly operations.

Directions for Use

Clean and dry the surfaces to be bonded before application. Apply tesa 68614 to the first substrate, then remove the liner and bond the second surface, pressing firmly to maximize adhesive contact. Allow the full 14-day adhesion development period for applications requiring maximum bond strength, recognizing that initial adhesion will be lower immediately after application.
