Resin Technology Group KONA 870FT High Thermal K Casting System
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Mix ratio 100 to 7 by weight.

KONA 870 FT with HARDENER #7 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 coefficients, thermal shock resistance, high heat transfer capabilities and outstanding electrical properties. Fully cured KONA 870 FT with HARDENER #7 is highly resistant to weather, water, gases and vapors, petroleum lubricants and fuels and many mild acids and alkalis.

Applications:

KONA 870 FT is a versatile epoxy casting system which may be cured with a room temperature or elevated temperature curing agent. Select the catalyst which best suits your requirements.
