Ecoat Challenges For BEVs


Production of BEVs at greenfield and brownfield plants places new challenges on the E-coat line. The increased complexity of the body reinforcement needed to support the battery weight and the increased use of mixed metal substrates means that the E-coat product must offer a broader bake window to ensure cure and compatibility with a range of substrates and pretreatments. This enhanced capability required of the E-coat product all takes place under the increasing demands for sustainability improvements in the paint shop.

To meet these new challenges, Axalta has developed AquaEC™ Flex. We will review the key attributes of this new E-coat:

  1. broad bake capability with cure at lower temperatures
  2. ultra-high throw power to ensure coverage of complex interiors while maintaining a low overall usage
  3. capability for superior anti-corrosion performance including edge protection

In addition, this paper will highlight the robust on-line performance of EC Flex (resistance to phosphate and other contaminates and low mapping sensitivity) within the context of improved sustainability from reduced water usage and energy consumption.
