Potting Compounds & Encapsulants
Two-part epoxy, silicone and polyurethane potting compounds that seal electronics against moisture, vibration, chemicals and heat.
Protect Electronics with the Right Encapsulant
A potting compound is a liquid resin that is poured around an electronic assembly and cured to form a solid protective block. It shields components from moisture, dust, chemicals, thermal shock and mechanical vibration, while improving electrical insulation and dissipating heat.
JOME manufactures epoxy, silicone and polyurethane potting systems — including thermally conductive and flame-retardant grades — so you can match the encapsulant precisely to your operating environment, thermal load and reliability targets.
Why Pot Your Electronics with JOME

Frequently Asked Questions
Potting fully fills an enclosure around the component, while encapsulation coats the component in a defined layer. Both protect electronics; JOME supplies resins suitable for either process.
Epoxy offers the highest rigidity and chemical resistance, silicone excels at high temperatures and flexibility, and polyurethane gives the best vibration damping. The right choice depends on temperature range, stress and reworkability.
Yes. Thermally conductive potting compounds are filled with ceramic or mineral fillers to move heat away from components while still providing full encapsulation and electrical insulation.
Yes, we offer flame-retardant epoxy and polyurethane potting grades suitable for safety-critical and high-voltage applications.
