Gießharz

Mehr als eine Rahmen-Handlung: Der Verguss (Potting) ganzer Baugruppen in ihrem Gehäuse erfordert reichlich Fachwissen über Torsion und Temperaturbeständigkeit. Gerade für innovative Lösungen muss man auch mal rückwärts denken.

Beim Vergussmaterial beginnen wir immer am Ende: dem fertigen Endprodukt am Einsatzort. WERNER WIRTH schockt da nichts mehr, selbst wüstenartige Temperaturschwankungen oder Vibrationen, die eigentlich nur noch alte Traktoren produzieren.

Deshalb suchen wir gemeinsam mit Ihnen jenes Material, das ebenso resistent ist. WERNER WIRTH liefert Ein- und Zweikomponentenlösungen, Polyurethane und Polybuthadine, Silikone und Epoxydharze. Profitieren Sie außerdem von schnellen Probereihen in unserer Laborfertigung – und der langjährigen Erfahrung, die so manchen Test überflüssig macht.

Potting empfiehlt sich für harte Umwelt-
bedingungen wie Offshore-Komponenten. Wir setzen dabei auf die bewährten und wirtschaftlichen Gießharze von BECTRON.
