Summary

The rheology of cold setting cashew nut shell liquid-formaldehyde resin adhesives has been studied both with aCoutte Viscometer and a penetro-viscometer.

The results are shown in graphs. The adhesive system was found to exhibit dilatancy. The viscosity versus time curves show only the last two parts of the corresponding casein glue curve. Mow curves indicate that in the early stages the system exhibits dilatancy but later shows a yield value.

Zusammenfassung

Die Rheologie von kalthärtendem Akajou-Nußschalenöl Formaldehyd-Harz-Klebemittel wurde sowohl mit demCoutte-Viskometer als auch mit dem Penetro-Viskometer gemessen. Die Ergebnisse sind graphisch dargestellt. Das klebende System zeigt Dilatanz. Die Kurven: Viskosität gegen Zeit ergeben nur die letzten beiden Teile der entsprechenden Caseinleim-Kurve. Die Fließkurven zeigen, daß in den ersten Stadien das System dilatant ist, später aber eine Fließgrenze besitzt.
