We meet your production needs with a wide variety of potting compound formulations, and extensive experience in custom development.
We formulate performance POTTING COMPOUNDS that are poured or cast into devices in order to protect electronic and mechanical components. Insulate, protect, and secure them in place with minimal ton o shrinkage, excellent adhesion, high dimensional stability, and optimum dielectric properties.
Potting compounds are 2-component systems that harden at room temperature or are heat cured. Many of our Potting Compounds are UL 1446 recognized for use up to 180C.
Our potting compounds contain minerals such as aluminum oxide, silicon dioxide, and calcium carbonate. These fillers create thermal conductivity, low coefficient of expansion, minimum shrinkage and reduce cost. Our UL 94V0 (Flame Retardant) potting compounds are designed to suppress flame in cross sections as small as 1/8”.
