Frequently asked questions

Go to help center

Potting involves filling an entire enclosure for maximum protection against environments. Encapsulation is a protective coating for components, offering a lighter level of protection.

Choose epoxy for hard, protective shellssilicone for flexibility and high heat, and urethane for vibration resistance and good adhesion.

Yes. Many of our compounds are UL 94 V-0 recognized and meet TUV standards for flame retardancy and electrical insulation.

Cure times range from 30 minutes for fast-processing grades to 24 hours for deep section pours. Heat can accelerate curing.
