Polyurethane

Alleskönner mit guten Haftvermögen

Polyurethane bieten vielfältige Einsatzmöglichkeiten und sind für ihr breites Einsatzspektrum bekannt. Von flexibel bis hart, haben eine gute Haftung auf vielen Substraten und zeichnen sich durch eine gute bis sehr gute Beständigkeit gegenüber vielen Substanzen aus. Je nach Bedarf können Sie ein- oder zweikomponentig eingesetzt werden. Modifizierte Polyurethane können mit UV-Licht gehärtet werden.

Polyurethane Einkomponenten Klebstoffe

Einkomponenten Polyurethane (1K-PUR-Klebstoffe) härten durch Aufnahme von Luftfeuchtigkeit zu einem Elastomer aus. Die 1K-PUR-Klebstoffe sind in der Regel pastös, standfest und werden mittels Handpistole oder aus Verarbeitungsanlagen raupenförmig in ca. 3 bis über 10 mm Schichtstärke aufgetragen. WERNER WIRTH bietet Polyurethane auch lösungsmittelfrei, UV-härtend und thermisch härtend an.
