Product Description
CoolTherm SC-6717 is a red silicone resin component used with CoolTherm SC-6731 hardener for solvent-free RTV potting, encapsulating, and coating of electrical and electronic components. Typical resin viscosity is 17,000 cP at 25 deg C. Documented SC-6717:SC-6731 ratios of 100:0.1, 100:0.5, and 100:5 by weight provide working lives of 6 to 8, 2 to 3, and 1.5 to 2 hours, respectively, with corresponding room-temperature cure times of 24, 12 to 16, and 8 to 12 hours. Typical cured properties for the documented system include 0.3 W/(m K) thermal conductivity, 60 Shore A hardness, and 19.7 kV/mm dielectric strength.
Key features
- Resin viscosity: Typical SC-6717 resin viscosity is 17,000 cP at 25 deg C.
- Ratio-controlled processing window: Mix ratios from 100:0.1 to 100:5 by weight provide working lives from 1.5 to 8 hours and cure times from 8 to 24 hours at 25 deg C.
- System dielectric strength: Typical cured dielectric strength of the documented SC-6717/SC-6731 system is 19.7 kV/mm.
Applications
Potting, encapsulating, or coating electrical and electronic components when SC-6717 is combined with SC-6731 hardener.
