Import Electronic Potting Compound Silicone — Buy in Bulk from Supplier in China

The Electronic potting compound silicone supplied by Hongyejie Cop. is a two-part, addition-cure silicone system formulated for encapsulating sensitive electronic assemblies. It cures at room temperature with minimal shrinkage and exhibits a Shore A hardness of 20 to 30 after curing, as stated in the product data. The compound has a viscosity range of 1,000 to 5,000 mPa·s before curing, enabling easy dispensing and penetration into tight component gaps without air entrapment.

Typical formulations for this class of silicone potting compounds include silica fillers to enhance thermal conductivity, with values commonly ranging from 0.6 to 1.2 W/m·K. The material resists moisture ingress with a water absorption rate below 0.5% after 24 hours immersion, and maintains flexibility across a temperature range of -40°C to 180°C. It adheres well to FR-4, copper, aluminum, and ceramic substrates without primers, a standard trait for industrial-grade silicone potting systems.

This compound is primarily used in automotive sensor modules, LED drivers, and power supply units where environmental sealing is critical. Buyers include OEMs in the automotive electronics sector and contract manufacturers servicing industrial control systems. Packaging is typically supplied in 1kg or 5kg dual-cartridge systems with static mixers. Trade terms are FOB Shenzhen, with minimum order quantities typically starting at 20kg, subject to confirmation with the supplier.

Hongyejie Cop. is a manufacturer based in Shenzhen, Guangdong, with a physical address listed at Building A, No.3, Hongling First Road.
