Adhesives | Measurement of Adhesives with the Rotational Rheometer RheolabQC

This report explains how adhesives can be measured with the RheolabQC. A comparison of the structural decomposition, sagging behavior and yield stress of two adhesives is shown.

Adhesives are used to join surfaces, typically by changing their phase from liquid to solid. Sometimes this is triggered by a temperature change (hotmelt adhesives), in other cases the glue hardens at ambient conditions (contact adhesives) e.g. due to solvent evaporation or due to the humidity of the surrounding air.

In this report, the application behavior of two sealants is investigated. Structural decomposition, sagging and yield stress are significant quality characteristics for adhesives and sealants.

These characteristics contribute substantially to whether a product is viewed negatively or positively by the end user.
