Potting Compound for Electronics
How to encapsulate electronic assemblies for moisture, vibration and thermal protection — and which potting compound to choose.
Encapsulate Electronics the Right Way
Potting electronics means filling an enclosure with a curable resin to protect the assembly from moisture, dust, vibration, chemicals and heat. The choice of resin determines protection level, heat dissipation and reworkability.
Use epoxy for rigid, chemical-resistant protection; silicone for high temperatures and stress relief; and polyurethane for vibration damping. JOME supplies all three, including thermally conductive and flame-retardant grades.

- Adhesion to enclosure materials
- Weight and fill volume
Frequently Asked Questions
Epoxy gives the toughest, most chemical-resistant protection; silicone handles high heat and stress; polyurethane damps vibration. Choose based on temperature, stress and whether rework is needed.
Yes, especially thermally conductive potting compounds, which encapsulate the assembly while conducting heat away from components.
Potting gives maximum protection by fully encapsulating the assembly; conformal coating is lighter and easier to rework. The right choice depends on the protection level required.
