Potting Materials

Potting Materials: Protection all around

Henkel’s potting and encapsulation systems deliver superior printed circuit board (PCB) and electrical device protection. In challenging environments such as automotive, aerospace and industrial operations, operating temperature and thermal conductivity boundaries are pushed to their extreme. Potting materials safeguard electronics with electrical insulation and mechanical strength, ensuring device longevity and reliable function.

An extensive range of formulations are available within Henkel’s potting portfolio, with excellent adhesion strength to various surface types and provide electrical insulation and thermal stability within a wide operating temperature window.
