Original Press Release:



High Speed Production EPOXY for Encapsulating Motors & Electronics



efi-POLYMERS Denver Colorado - Chicago Illinois - Atlanta Georgia announces a HIGH SPEED thermally-conductive EPOXY for automated encapsulation of motors and electronic parts. With the proper dispensing equipment, a room temperature cure (optimal for high volume production) is possible. At 1000 CPS mixed viscosity, complete impregnation is vital to the success of your product.

20206/50013 Electrical Potting System is a black, filled, epoxy that has a moderate mixed viscosity and a long gel time. UL 1446 recognized as a potting compound up to 180°C (class H): UL File No. E 210549.

USE
Designed for ambient cured applications requiring complete impregnation. System may be used with or without vacuum. The moderate viscosity and long gel time make this a viable system for high speed production or manual applications. The cured system has excellent thermal shock resistance.
