Epoxy Resin Casting

Epoxy resin casting is a pure resin system without filler. It is designed for electronic component potting and precision electrical part impregnation. This Product goes through pre-reaction and vacuum degassing in 6 reactors. It then passes a three-stage filtration system. This removes micron-level mechanical impurities. The result is a clear liquid resin with controlled color difference. It is available for OEM replacement, aftermarket supply, and bulk orders.

Our epoxy resin casting fits many small electronic and precision electrical parts. It is used in small electronic transformers and inductor vacuum impregnation. It also suits high-voltage relays and connector cavity potting. Sensors and micro motor stator insulation use it. PCB assemblies and thick-film circuits use it for protective coating. Precision electrical parts use it for gap filling and sealing. The table below shows typical equipment matching.

These values help buyers compare materials. They also help engineers set process parameters. The data comes from third-party CMA and SGS reports. Each batch is traceable.

This material supports replacement and custom supply. Buyers often come with a device model, drawing, or performance target. They need a material that matches the original insulation system. We review the voltage level, wall thickness, and curing method. Then we recommend the right grade. The table below shows common replacement scenarios.

This material offers several engineering benefits. It has stable electrical strength from 28 to 32 kV/mm. It keeps volume resistivity at or above 1.0×10^15 Ω·cm. It holds water content below 0.05%. It also has low viscosity from 400 to 800 mPa·s. These features reduce water tree aging in high-voltage fields. They also improve impregnation depth. The material flows well in small gaps. It cures with low exotherm. This helps protect sensitive electronic parts.

We control quality at every production step. Each batch goes through four inspection stages. These are incoming material check, process check, finished product check, and shipment check. We test electrical strength, viscosity, and water content. We also keep samples for traceability. Our factory holds CMA and SGS reports. These reports verify the key values in the specification table. We provide test data for each shipment.

Buyers can use the table below to match the right grade.

First, confirm the equipment type and voltage level. Second, check the required insulation thickness and curing method. Third, review the viscosity and gel time needs. Fourth, compare electrical strength and water content. Fifth, request a free sample for line testing.
