TESA 74515

tesa® 74515 – 125 µm LSE Transparent Transfer Tape

High-Performance Transfer Tape for Low Surface Energy (LSE) Substrates

Product Overview

tesa® 74515 is a transparent, double-sided transfer tape engineered for high-performance bonding on low surface

energy (LSE) materials such as PP, PE and EPDM – without the need for primer.

It features a 125 µm thick tackified acrylic adhesive with no carrier backing, providing excellent initial tack, strong shear

strength and reliable long-term adhesion. The conformable adhesive layer adapts to slightly rough or flexible surfaces,

ensuring consistent wet-out, good stress distribution and clean, invisible bonds in demanding industrial and precision

mounting applications.

Primerless bonding to LSE plastics and coated surfaces (PP, PE, EPDM, etc.).
High bonding power at just 125 µm total thickness.
Carrier-free, thick adhesive layer that adapts to surface irregularities and flexible substrates.
Excellent initial tack and shear strength for secure, long-term mounting.
Reliable performance under humidity, temperature cycling and short-term heat up to 200 °C.
Ideal for applications requiring clean aesthetics and invisible bonding lines.

Versatile bonding solution for a wide range of demanding industrial applications.
Primerless adhesion to LSE substrates such as PP, PE and EPDM.
Long-term mounting on hard-to-bond materials (e.g. gaskets, molded parts, textured plastics).
Industrial bonding of foams, films and flexible materials.
Design and display applications requiring invisible, seamless bonding.

*Non-standard dimensions are subject to feasibility and business case evaluation.

Slitting: Recommended material temperature 2–10 °C to reduce adhesive oozing and improve cut quality.
Die-cutting: Non-stick coated tools are recommended to minimise adhesive build-up.
Laminating: Use metal and rubber rollers with moderate pressure for uniform bonding.
Application technique: Apply high pressure (e.g. tape roller) to ensure full surface contact.
Recommended application temperature: approx. 10–40 °C for both tape and substrates.

Low VOC: Tested according to VDA 278 – does not contain substances restricted by drafted GB regulations (China).
UL 969: Certification pending.

Store in original packaging, away from light and heat sources.
