DELO-DUOPOX TC8686 combines structural bonding and connection of the thermal management system<\/strong> in one step instead of mechanically connecting the battery cells and then using so-called gap fillers for heat dissipation. This saves one process step and simplifies production. The product is not only suitable for mild hybrids, but also for conventional hybrids and for other batteries in the low-voltage range, such as those used in e-bikes and e-scooters.<\/p>\n\n\n\nAdhesive properties optimized for batteries<\/h3>\n\n\n\n
DELO-DUOPOX TC8686 is designed for temperatures ranging from -40 to +85 \u00b0C and offers good strength on battery cells and typical housing materials<\/strong>. For example, the tensile shear strength on aluminium is 18 N\/mm\u00b2. The adhesive also meets the strength requirements of the automotive industry at typical operating temperatures between 10 and 40 \u00b0C up to the maximum service temperature of 80 \u00b0C, a temperature at which the battery electrolyte can already be irreversibly damaged. The adhesive\u2019s properties in terms of elongation at tear also help to meet these requirements. A certain flexibility compensates for the different thermal expansion<\/strong> behaviours of cell and housing material during operation. The product\u2019s thermal conductivity, which is a very important factor for battery cell applications, is 1.1 W\/mK. Another major benefit is that it meets the requirements for flame retardancy according to UL 94 V-0.<\/p>\n\n\n\nDeveloped with a view to high-volume series production<\/h3>\n\n\n\n
DELO-DUOPOX TC8686 has also been optimized for manufacturing processes. It offers a simple mixing ratio of 2:1<\/strong>. It has a processing time of approximately 30 min after mixing. This is long enough for prototypes and small series and fast enough for fully automated systems. After four hours, the adhesive reaches its initial strength; 90 % of its final strength can be achieved after 24 hours. Even with low heat input, this amount of time can be reduced significantly. Depending on the battery electrolyte used, temperatures of 60 \u00b0C are conceivable. Beige in colour, the product is easily detectable by cameras<\/strong>, ensuring accurate application control. In addition, the filler for thermal conductivity is only slightly abrasive, contributing to the dispensing systems\u2019 long lifetimes. The product being classified in transport category 1 and suitable for transport and storage at room temperature, complicated logistics processes are avoided.<\/p>\n","protected":false},"excerpt":{"rendered":"DELO has introduced a heat-conductive adhesive for hybrid vehicle batteries, the DELO-DUOPOX TC8686.
