This HVLP spray-applied, oven-cure electrical insulation coating forms a thin, durable barrier that electrically isolates conductive components while protecting them from corrosion, solvents, and harsh operating environments. Built on Cerakote's proven H Series ceramic technology, H-900 provides long-term dielectric stability without compromising mechanical durability or dimensional tolerances.

Designed for components that require electrical isolation without added bulk, H-900 combines Cerakote’s proprietary ceramic technology with advanced dielectric performance for mission-critical applications.


Performance Specifications

Cerakote H-900 Electrical Barrier Coating is engineered for dependable electrical and environmental performance:

  • Maximum Operating Temperature: 500+°F
  • Dielectric Strength: 3000 V/mil
  • Corrected Dissipation Factor (D): 0.006
  • Dielectric Constant (k): 1.18
  • Application: Spray-applied, oven cure
  • System: Two-component (includes catalyst)

Designed for Aerospace and Defense Systems

Modern aerospace and defense platforms rely on compact electrical architectures where insulation performance, weight control, and environmental resistance are essential. Cerakote H-900 provides a durable dielectric layer capable of maintaining electrical isolation in high-reliability systems.

Typical defense and aerospace applications include:

  • Avionics housings and electronics enclosures
  • Satellite and space vehicle components
  • UAV and unmanned system electronics
  • Electrical connectors and sensor assemblies
  • Power distribution hardware and bus bars
  • Guidance, navigation, and communication systems
  • Defense electronics and control modules

Its thin-film profile allows insulation without excessive weight or dimensional buildup — ideal for tight tolerance aerospace assemblies. The ceramic foundation enhances resistance to vibration, thermal cycling, and environmental exposure encountered in high-altitude and space environments.

Industrial & EV Applications

Beyond aerospace, this electrical barrier coating is ideal for:

  • Battery systems and EV components
  • Bus bars and conductive hardware
  • Industrial automation equipment
  • Robotics and control modules
  • Power generation and distribution components
  • Fasteners requiring both corrosion resistance and electrical isolation

Because it maintains strong dielectric performance while resisting chemicals and solvents, H-900 performs in environments where conventional insulation coatings may fail.

Advanced Ceramic Technology

The foundation of Cerakote H Series coatings is a proprietary ceramic-polymer technology that delivers:

  • High adhesion to properly prepared substrates
  • Excellent resistance to solvents and chemicals
  • Corrosion protection for metal components
  • Flexibility to resist cracking under vibration or stress
  • Long-term durability in operational environments

This combination of ceramic coating toughness and dielectric insulation performance makes H-900 a versatile solution for electrically isolating metal components without environmental degradation or sacrificing structural integrity.

A Thin-Film Dielectric Solution for Modern Systems

When electrical insulation, durability, and environmental resistance are equally critical, Cerakote H-900 Electrical Barrier delivers a professional-grade ceramic dielectric coating solution built for performance.

Cerakote H-900 Electrical Barrier offers Engineers and Quality Control teams a reliable dielectric coating solution that integrates easily into existing spray and oven-cure finishing processes.
