Thermal management specialist Zircotec has unveiled its new range of ElectroHold high-performance coatings for EV battery enclosures and cooling plates. ElectroHold range features individual dielectric, flameproof, and EMI coatings, while Zircotec’s ElectroHold OMNI SHIELD product combines all three in one coating.
All products are lightweight, can be easily packaged into existing automotive design infrastructures, protect against water ingress, corrosion and chemical attack, and provide the highest performance and adherence levels during normal operating conditions.
The specific features of each product are:
- ElectroHold DIELECTRIC
Available as a lightweight polymer-based coating or a ceramic coating with a polymer sealant. Prevents electrical conductivity between components to ensure safety and eliminate the risk of short-circuiting and overheating of batteries and battery cells. Coatings provide high dielectric strength on various components, offering up to 42 Kv/mm or 10 Kv/mm coupled with good thermal conductivity to aid heat removal. - ElectroHold FLAMEPROOF
A proven, lightweight, high-performance thermal barrier coating for battery boxes and covers that gives short-term flame protection at 1,400°C and extended protection at 700°C. Suitable for use on steel, aluminium, composite and plastic substrates without any post-application electrical impact being caused. - ElectroHold EMI SHIELD
An electrically-conductive battery box and cover coating that both prevents EM leakage and protects critical components from EM interference. These high-integrity, metallic-based coatings are ultra-thin (~50 μm), lightweight (~135 grams per m2), and can operate up to temperatures of 600ºC. - ElectroHold OMNI SHIELD
A unique product that provides flameproof, dielectric and EMI shielding protection in a single coating. This high-integrity application is lightweight and applied in multiple layers, meaning specific parameters can be used to secure application-specific requirements. Suitable for use on various components, including battery boxes, cooling plates, and inverter housings.
“Our ElectroHold range gives OEMs and niche manufacturers easy access to a high-performance and versatile set of both ceramic and polymer coatings that can either be used in isolation to achieve specific flameproofing, dielectric or EMI shielding results – or in a single solution that delivers all three forms of protection.”
Dominic Graham, Engineering Manager at Zircotec
