Mix ratio 100 to 4 by weight. KONA 870 FTFR with HARDENER #9 is a versatile epoxy casting system that exhibits unusually high thermal conductivity and low thermal expansion. It is recommended for electronic/electrical casting and encapsulating applications that require a unique combination of excellent wetting, flow, good thermal expansion coefficient, thermal shock resistance, high heat transfer capabilities and outstanding electrical properties. Fully cured KONA 870 FTFR with HARDENER #9 is highly resistant to water, weather, gases and vapors, petroleum lubricants and fuels, and many mild acids and alkalis. This system is room temperature curing with a 45 minute pot life (1 pound mass), has a high viscosity with good handling properties, and is tough and rigid at all temperatures to 300°F.
