22 KV/Mm Epoxy Potting Compound Glue Potting For Capacitors, Transformers, Sensors, LED Modules Electronic Potting Silicone Rubber
Product description:
Epoxy resin potting compound is a thermosetting encapsulating material based on epoxy resin. Through mixing with a curing agent, it reacts to form a robust and durable insulator, commonly used for insulation, moisture protection, dustproofing, waterproofing, and fixing of electronic components. It comes in two types: two-component room-temperature curing and one-component high-temperature curing. It possesses excellent insulation properties, chemical resistance, high mechanical strength, and adhesion.
Application:
Main Applications:
Electronic Component Packaging: Providing insulation and physical protection for components such as capacitors, transformers, sensors, and LED modules.
Circuit Board Protection: Used for the confidentiality, insulation, and moisture protection of circuit boards.
Automotive, Aerospace, and Other Fields: Used in electronic products requiring high strength and resistance to harsh environments.
