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
Excellent flexibility, toughness and adhesion
Busbar and metal structure insulation protection
Case and water cooling plate radiator insulation coating
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
The insulation coating thickness is 100μm and can withstand high voltage of 6000V
High reliability, excellent performance can be maintained after long-term aging
3 years of automotive grade mass production, production yield ≥98%
