Dymax, a manufacturer of rapid-curing materials and equipment, recently introduced its latest adhesive for the assembly of electric vehicle (EV) batteries. The 9501-F curing adhesive is a solvent-free, one-component acrylated urethane that can replace solvent-based epoxy urethane and silicone materials, making the entire production process significantly more environmentally friendly.

This low shrinkage product has excellent bond strength to common substrates such as PC, PC/ABS, nickel plated steel, and aluminum and is especially designed for fixturing cylindrical battery cells to plastic bases Source: DymaxSource: Dymaxand holders.

9501-F cures tack free in seconds upon exposure to ultraviolet/visible light energy and is also LED curable at 385 nm wavelength. Fast cure time allows assembled components to be processed quickly in line, increasing throughput capacity and lowering overall manufacturing and labor costs. It also exhibits great reliability performance through common EV tests, such as high temperature/high humidity and thermal shock.

With a viscosity of 10,000 centipoise, the adhesive has greater resistance to flow and stays in place when dispensed onto parts, so accurate assembly and on-demand cure is easily achieved. The product is also a good choice for shallow potting and sealing of connectors, thermal switches and sensors as well as for tamper proofing applications. For easy quality inspection, the material fluoresces bright blue in color.
