Potting and Encapsulating for Control Modules

Choose from a full line of electronic potting and encapsulating compounds designed to protect control modules and timers from the elements, both chemical and natural. These resins are excellent for use in a variety of small, sensitive electronics. The low viscosity properties of these compounds allow for easy reach of intricate components within the control modules and other similar electronic devices. Sensitive components are well protected and held stable with our high-quality electric potting compounds.

Our epoxy and polyurethane encapsulants are used in environments that require good thermal shock and vibration resistance, as well as resistance to harsh chemicals. Many of our potting materials are UL rated for enhanced fire resistance.
