Product description
tesa® 4965 is a transparent, double sided self-adhesive tape consisting of a PET backing and a tackified acrylic adhesive. The bonding tape is suitable for the most demanding applications such as heavy stress, high temperatures of up to 200°C and critical substrates. tesa® 4965 features an especially reliable bond, even to low surface energy substrates. The mounting tape is highly resistant to ageing, humidity and UV light and can withstand softeners and chemicals. tesa® 4965 features a good tack and immediate usability right after assembly. The high-performance tape shows excellent performance in demanding industrial, permanent and outdoor applications. The tape is available with several liner variants. tesa® 4965 is recognised according to UL standard 969. UL file: MH 18055. Thanks to its outstanding technical specifications, this extensively tested adhesive tape fulfils all the requirements of DIN EN 45545-2 R1 and HL3, the highest hazard level.
