LSE Adhesion: Primerless bonding to plastics and coated surfaces.
Thin & Strong: High bonding power at just 125µm thickness.
Gap-Filling: Thick adhesive adapts to surface irregularities.
All product featuresProduct description
tesa® 74515 is a transparent, 125µm double-sided transfer tape developed for high-performance bonding on low surface energy (LSE) substrates such as PP, PE, and EPDM. It features a tackified acrylic adhesive that delivers excellent initial tack, strong shear strength, and reliable adhesion without the need for primers. The thick, conformable adhesive layer—without a carrier backing—adapts well to slightly rough or flexible surfaces, ensuring consistent wet-out and stress distribution. tesa® 74515 performs reliably under demanding environmental conditions, including humidity and short-term exposure to temperatures up to 200°C, making it ideal for industrial and precision mounting applications where clean aesthetics and long-term durability are essential.
