Water-based epoxy functional coating
Metal heat dissipation substrate insulation and thermal protection
The power module is insulated from the metal structure
Suitable for aluminum alloy radiators, metal shells and other components
Meet the high reliability insulation requirements of communication equipment
The coating dries quickly to form a film, forming initial solid strength.
Support R corner/groove/side/different 3D design spraying
Thermal conductive insulation coating thermal resistance as low as 0.176℃·in²/W
Thickness of 100~250μm can withstand high voltage of 3000~6000V
High reliability, excellent performance can be maintained after long-term aging
3 years of automotive grade mass production, production yield ≥98%
