SYLGARD™ 170 Silicone Encapsulant Flame Retardant Potting Solution for Electronics​​

SYLGARD™ 170 Silicone Encapsulant Flexible Flame-Retardant Potting Solution for Electronics​​

Basic Properties

SYLGARD™ 170 is a two-part, 1:1 mix ratio black silicone elastomer featuring low mixed viscosity (2135 cP), moderate thermal conductivity (0.48 W/mK), and rapid curing at room temperature or with heat acceleration. It is UL 94 V-0 flame-rated and EN45545-2 HL3 certified for railway applications, ideal for electronic potting and encapsulation.

Product Description

Supplied as a two-part liquid, it cures into a flexible elastomer for PCB and electronic assembly protection. Curing is non-exothermic and independent of sectional thickness, requiring no post-cure. It enhances flow in narrow spaces and complex geometries, provides stress relief during thermal cycling, and prevents damage from rigid encapsulants. Adhesion requires a primer (standard version.

Enhanced Characteristics

1. Processing Versatility​​: Low viscosity (Part A: 3160 cP / Part B: 1110 cP) ensures high flowability; 15-minute pot life at 25°C enables precise dispensing.
2. ​​Multi-Cure Options​​: 24-hour cure at 25°C / 25-minute heat cure at 70°C / 10-minute rapid cure at 100°C.
3. ​​Reliability​​: Volume resistivity 5.6×10¹⁷ Ω·cm, dielectric strength 18 kV/mm (100 Hz), flame resistance compliant with MIL-PRF-23586F.

Application Scenarios

Core Applications​​ (per document): Power supplies, connectors, sensors, industrial controls, transformers, amplifiers, high-voltage resistor packs, relays.
​​Extended Use Cases​​ (externally verified¹): EV battery management systems (BMS), railway signaling devices, high-voltage charging station circuitry.
