DELO provides thermally conductive battery adhesive for hybrid autos

Industrial adhesive producer DELO has launched a structural adhesive for batteries utilized in hybrid autos. Designed for high-volume collection manufacturing, DELO-DUOPOX TC8686 is thermally conductive and flame-retardant.

DELO says its new adhesive, which is presently being utilized by an automotive provider within the ramp-up part of manufacturing, is appropriate for low-voltage batteries utilized in hybrid autos, e-bikes and e-scooters. The adhesive permits battery cells to be bonded right into a battery’s housing and dissipates the warmth generated throughout operation.

As an alternative of mechanically connecting the battery cells after which utilizing hole fillers for warmth dissipation, DELO-DUOPOX TC8686 combines the 2 into one step.

DELO-DUOPOX TC8686 is designed for temperatures starting from -40° C to +85° C. The adhesive’s tensile shear power on aluminum is eighteen N/mm², which meets automotive power necessities at most service temperatures of 80° C. Its flexibility compensates for the totally different thermal enlargement behaviors of cell and housing materials throughout operation.

The adhesive has a thermal conductivity of 1.1 W/m*Ok. It additionally meets the necessities for flame retardancy in line with UL 94 V-0.

DELO-DUOPOX TC8686 has a mixing ratio of two:1 and requires a 30-minute processing time after mixing. After 4 hours, the adhesive reaches its preliminary power. Ninety % of its remaining power might be achieved after 24 hours. With a low warmth enter, the curing time might be diminished. 

Beige in colour, the product is detectable by cameras, facilitating correct software management. Additionally, the thermal conductivity filler is simply barely abrasive, which contributes to the allotting techniques’ lengthy lifespan. The product is classed in transport class 1, and might be saved at room temperature.
