As electric vehicles evolve, safety remains a top priority.
Dow, a MD Poland partner, is at the forefront with advanced materials for fire protection of electric vehicle batteries (BFP) designed to help prevent thermal runaway events, protecting both passengers and performance.
Innovative solutions for electric vehicle battery protection
Solutions for the thermal and environmental protection of electric vehicle batteries include a range of technologies designed to ensure safety and reliable performance even in extreme conditions.
Depending on the application requirements, you can choose from coatings and encapsulants, silicone foams or high-consistency rubbers, each with specific characteristics in terms of heat resistance, electrical insulation and fire behaviour.
LSR coatings and encapsulants
Coatings and LSR encapsulants with room temperature curing and ceramisation in the event of thermal events or high temperatures provide effective protection against heat, flames and particle explosions.
Silicone foam
Rapid-curing, low-density silicone foam offers vibration reduction, electrical insulation and thermal protection and flame retardancy through ceramisation.
High-consistency rubbers
High-consistency rubbers offer rapid curing, superior electrical insulation and thermal protection and flame retardancy through ceramisation.

DOWSIL™ EA-3838 Fast Adhesive
DOWSIL™ EA-3838 Fast Adhesive is a fast-curing silicone adhesive at room temperature designed for the assembly of electronic components for motor vehicles, with excellent weather resistance and thermal stability.
Thanks to its reliability and consistent mechanical properties over time, it is also used in the manufacture and sealing of electric battery modules, where it is essential to ensure lasting adhesion and protection from thermal and environmental stress.
This adhesive is distinguished by its rapid and uniform deep polymerisation, which allows for quick handling of bonded components and an optimised assembly process.
Its paste-like consistency and non-self-levelling properties ensure precision application even on vertical surfaces, while its early adhesion at room temperature reduces processing times.
Key features include:
- Long-lasting adhesion to a wide variety of substrates, including metals, plastics and composite materials.
- High resistance to atmospheric agents and UV rays.
- Fast assembly process suitable for automated production lines.
- Elastomeric properties.
DOWSIL™ EA-3838 Fast Adhesive is therefore a versatile, high-performance solution for applications where safety, strength and speed of process are essential requirements, such as in electronic systems and battery structures for new-generation electric vehicles.
DOWSIL™ 3-8259 RF Silicone Foam Kit
DOWSIL™ 3-8259 RF Silicone Foam Kit is a two-component, room-temperature silicone foam system designed to be dispensed and cured directly onto components to form an integrated compression seal.
This solution ensures precise and uniform application, ideal for protecting modules and enclosures subject to thermal or environmental variations.
Its formulation is characterised by medium hardness (Shore 00) and low flow, which facilitates application even on inclined surfaces.
It is easy to use, thanks to its 1:1 mixing ratio, and allows for rapid curing at room temperature, eliminating the need for temporary storage of assembled parts.
Key features include:
- Low compression set, maintained even at high service temperatures.
- Stability and flexibility over a wide range of operating temperatures.
- Efficient and controlled application, suitable for automated processes.
- Elastomeric properties.
Thanks to these properties, DOWSIL™ 3-8259 RF Silicone Foam Kit is a reliable solution for sealing and thermal protection in applications where elastic and durable gaskets are required, such as in thermal management and electronic module protection systems.
DOWSIL™ EF-6555 Silicone Foam
DOWSIL™ EF-6555 Silicone Foam is a low-density silicone foam designed for the production of foam sheets for fire protection and thermal insulation of electric vehicle batteries.
Thanks to its lightweight and homogeneous structure, it offers an excellent combination of heat resistance, dimensional stability and insulation capacity, making it particularly suitable for applications where safety and thermal management are key priorities.
