#170 Silicone

Dow Corning Sylgard 170 Silicone Elastomer, Two-part, 1:1 mix, black, general purpose encapsulant with good flowability, long working time and flame resistance. Sylgard™ 170 Silicone Elastomer is suitable for use as an encapsulant or potting material. Potential applications includes: Power supplies, Connectors, Sensors, Industrial controls, Transformers, Amplifiers, High voltage resistor packs, and Relays.

• Low viscosity
• Long working time
• Room temp or heat accelerated cure
• Moderate thermal conductivity
• UL 94V-0 and Mil Spec tested to MIL-PRF-23586F (specifically listed material numbers only)
• Enahanced flow and fill in narrow spaces and around complex geometries
• Rapid, versatile cure processing controlled by temperature
• Provides stress relief in applications where hard, rigid encapsulants can cause damage during thermal cycling
• Can be considered for uses requiring added flame resistance and Mil Spec applications
