Product description
tesa® 51865 – Team 4965 Differential is a transparent, double-sided industrial mounting tape consisting of a PET backing and a tackified acrylic adhesive. The asymmetrical double-sided tape is the differential version of tesa® 4965 Original and its adhesive is based on a patented and protected product technology. The liner-covered side of tesa® 51865 – Team 4965 Differential has a high coating weight for maximum flexibility and versatility for multiple surface demands. The open side has a reduced coating weight that delivers a secure bond to flat profiles laminated under controlled conditions. tesa® 51865 – Team 4965 Differential is able to withstand numerous environmental factors such as humidity, UV light, and temperatures of up to 200°C for limited periods of time. The tackified acrylic adhesive offers excellent hold on various surfaces, high tack, and good shear strength.
Several products are equipped with this unique and high-performing product design. Together, these products make up Team 4965. This double-sided film tape assortment helps to easily select the most efficient tape based on customer demands, products, and processes. Explore the benefits of the full tesa® 4965 assortment here:
