Cerakote ELECTRICAL BARRIER H-900 ceramic coatings 4oz/bottle

Cerakote H-900 Electrical Barrier is a two-component oven-cured special dielectric insulating ceramic coating of H-series. Formulated with Cerakote proprietary ceramic polymer technology, it is engineered for high-reliability electrical isolation. Applied by HVLP spray, supplied with catalyst. A 150-mesh strainer SE-276 is required for filtration during application. It forms a thin coating layer, delivering stable electrical insulation together with corrosion resistance, chemical resistance, wear resistance and flexibility. It passes 14 CFR 25.853 vertical flammability test with self-extinguishing property. It is ideal for precision-tolerance parts without excessive dimension buildup

Cerakote H-900 delivers excellent dielectric insulation with dielectric strength of 3000 V/mil, low dielectric constant of 1.18 and low dissipation factor of 0.006 for stable long-term dielectric performance to prevent short circuits and leakage. It is applied as a thin coating with recommended dry film thickness of 75–100μm without affecting dimensional tolerances for precision parts. This coating offers all-in-one protection including long-term corrosion resistance on metal substrates, resistance to solvents and chemicals, good wear resistance, impact resistance and flexibility against cracking during bending. It can continuously withstand temperatures above 260°C (500℉) and holds aerospace flame retardant certification with self-extinguishing property and no burning drips. It achieves 5B adhesion on metal substrates, resists peeling and features stable spraying process suitable for mass production. Typical applications include conductive parts of power batteries, busbars and high-voltage distribution metal components for new energy vehicles and energy storage; avionics housings, sensor assemblies, power distribution hardware, UAV electronic modules and satellite electrical parts for aerospace and defense; automation control assemblies, generator conductive components, robot control modules and fasteners requiring insulation and corrosion protection for industrial electrical equipment, as well as high-voltage metal conductive components in confined spaces that need electrical isolation together with anti-corrosion and wear resistance.
