Potting

Component protection by the specialist WERNER WIRTH

More than just background: potting whole modules in their housing demands plenty of know-how about torsion and temperature resistance. Innovative solutions in particular often also entail thinking backwards.
With potting materials, we always begin at the end: the finished final product at its place of use. Nothing shocks WERNER WIRTH any more, not even the strongest vibrations or temperature fluctuations like those in the desert.

Potting resin for the toughest and most adverse conditions and weather

We know what we're doing and work together with you to find that special material that is robust and resilient in accordance with the requirements. WERNER WIRTH supplies one- and two-component solutions, polyurethane and polybutadiene, silicone and epoxy resins. You can also benefit from fast test series in our Working Lab, combined with many years of experience that can also eliminate the need for testing at all.
