Dowsil DC160 Organic Potting Glue AB Glue Electronic Component protection Packaging Sealant 49.8Kg

Product Attributes​​
Dowsil DC160 is a two-part, 1:1 mix ratio, dark gray silicone elastomer designed for general-purpose encapsulation. It offers good flowability, moderate thermal conductivity, and UL 94 V-0 flame resistance, making it suitable for a wide range of electrical and electronic applications. The material cures at room temperature or with heat acceleration, providing flexibility in processing.

Product Overview​​
Dowsil DC160 is a versatile, primerless silicone encapsulant that cures to a flexible elastomer without exotherm, ensuring consistent performance regardless of part thickness or confinement. It is ideal for protecting sensitive electronic components, such as power supplies, connectors, sensors, and transformers, from environmental stressors. The material’s flame-retardant properties (UL 94 V-0) and reliable electrical insulation make it a trusted choice for demanding industrial applications.

Special Properties (Expanded Attributes)​​
Dowsil DC160 stands out for its ​​moderate thermal conductivity (0.36 BTU/hr·ft·°F or 0.62 W/m·K)​​, balancing heat dissipation with electrical insulation. Its ​​Shore A hardness of 56​​ ensures mechanical flexibility, while its ​​dielectric strength (475 volts/mil or 19 kV/mm)​​ and ​​volume resistivity (5.6 × 10¹⁴ ohm·cm)​​ guarantee robust electrical performance. The material cures rapidly at room temperature (24 hours) or can be accelerated with heat (4 minutes at 100°C), offering process flexibility. Notably, it achieves a UL RTI (Relative Thermal Index) rating of ​​150°C​​, signifying long-term thermal stability.

Application Scenarios​​
Dowsil DC160 is widely used in ​​electronic potting and encapsulation​​, including:

• ​​Power supplies​​ (protection against thermal cycling and moisture).
• ​​Connectors and sensors​​ (ensuring insulation and mechanical durability).
• ​​Industrial controls and transformers​​ (flame-retardant encapsulation for safety compliance).
• ​​Automotive electronics​​ (vibration resistance and thermal management).
