Fireproofing
Passive Fire Protection with Intumescent Coatings
Originally used in construction, passive fire protection (PFP) or intumescent coatings are rapidly moving into the automotive space. Applying a thin, even layer of a PFP epoxy, polyurethane, or silicone to the outside of a battery pack protects it from extreme heat.
When a certain temperature is reached, the sprayed layer of intumescent coating expands, insulating the battery. This keeps the thermal event from reaching the passenger compartment of an electric vehicle (EV).
So that intumescent coating provides effective fire protection, the following must happen:
- Keep the high viscosity material at the correct temperature when being mixed.
- Dispense it at a continuous flow for reliable application.
- Monitor closely the mixing ratio.

FAQs
Fireproofing is necessary for EV batteries to ensure safety and prevent thermal runaway using materials like intumescent coatings, which expand when exposed to heat, creating a barrier that protects the battery cells from fire damage.
Fire protection solutions for EVs are methods and materials used to safeguard battery systems. These solutions absorb passive fire protection coatings insulating batteries and preventing heat from spreading.
An intumescent coating refers to fireproofing material that stretches out when heated thus forming a thick char layer which provides insulation and protects any underlying materials from high temperatures, proving to be essential for fireproofing EV batteries enhancing safety and performance.
Passive fire coatings slow down heat transfer to the protected surfaces creating a barrier during high temperatures, thus shielding the material beneath and maintaining the structural integrity during a fire.
PFP coatings are important due to several reasons such as:
- Thermal Insulation
- Fire Resistance
- Increased Safety for Passengers
- Improved Battery Performance
- Cost-Effective Application
- Environmental Benefits
It is possible to customize fire protection solutions for your EV batteries according to your needs. Patvin Engineering provides customized fire protection solutions for your specific needs thus being your best partner protecting your EV batteries.
