As the pace of EV adoption and innovation accelerates, OEMs and EV battery manufacturers are striving to develop more efficient ways to build batteries at scale. At the same time, fire protection is needed to ensure vehicle batteries provide the best possible safety in the case of accidents and fires. EV battery safety technologies that delay the spread of fire is therefore important.

To take on this challenge, Henkel has launched two new protective coating products designed to shield the battery housings against heat and fire in the case of a thermal runaway event - Loctite EA 9400 and Loctite FPC 5060.

When applied to battery packs, the coatings help to inhibit and delay the spread of fires. Meanwhile, their efficient and cost-effective application processes ensure that manufacturers can continue to optimize battery production without compromising on safety.

Whether due to mechanical, thermal, or electrical incidents – thermal runaway events can occur when a battery cell enters into a heating state and ignites a fire that spreads to neighboring cells.

Battery safety solutions help to reduce or slow such events, thereby increasing time for vehicle evacuation. This time window is increasingly subject to regulation: China has already enacted regulations that specify a required time window and other markets are expected to follow suit in due course as regulatory frameworks for EV safety evolve.

Designed for automated mass production, Loctite EA 9400 and Loctite FPC 5060 can be applied either by “spray” or “flat stream” and both are compatible with common automated dispensing systems.

In line with Henkel’s commitment to sustainability, Loctite 9400 and Loctite FPC 5060 both cure at room temperature, thereby helping reduce energy consumption and emissions.

• Loctite EA 9400
  Loctite EA 9400 is a two-component, active flame-retardant, epoxy-based fire protective coating designed for the battery pack housing. With minimizing weight of EVs and batteries a high priority, the product has been designed to be applied in a thin layer that does not add much weight to the battery.
  
  Thanks to its foaming characteristics and tough formulation for environmental resistance, Loctite EA 9400 can be applied on both the inside and outside of the battery pack housing to provide versatility. As well as providing light-weight thermal protection, it also prevents battery box corrosion.

• Loctite FPC 5060
  Also created for the battery pack housing, Loctite FPC 5060 is a one-component, water-based, inorganic material that does not form any smoke or fumes when exposed to flame.  Its unique, inorganic formulation does not include any hazardous chemicals and produces no smoke, no fumes, and no carbon during a fire – thereby further protecting passengers.
