Porosity in dielectric coating refers to microscopic air pockets, bubbles, or voids that can form within the coating layer, affecting the insulation in EV battery assemblies.

A minor reduction in coating thickness at an edge can lower insulation resistance below acceptable thresholds, leading to electrical arcing,or outright machine failure.

Dielectric coupon testing is a low-risk testing process for validating dielectric coating on aluminium components. These aluminium test coupons would let us simulate how your dielectric coating will perform under real-world conditions, before coating at scale.
