We look forward to having in-depth exchanges with you and exploring more composite material application technologies and solutions.
Water-based epoxy functional coating
The coating uses water as the solvent and is environmentally friendly
Precise spraying, stable process, Cpk up to 1.67
Excellent flexibility, toughness and adhesion
Insulating coating can be applied to housing and water cooling plate insulation
In MOSFET applications, thermally conductive insulating coatings can be used as an alternative solution to ceramic insulating sheets.
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%
