Understanding Viscoelastic Adhesives

Viscoelastic adhesives are a unique class of materials that exhibit both viscous and elastic characteristics when undergoing deformation. These properties make them highly versatile and suitable for a wide range of applications, from industrial manufacturing to consumer products. The ability to accurately measure and predict their flowability and application behaviour is crucial for ensuring their effectiveness and reliability in real-world applications.

Why Oscillatory Rheometry?

Oscillatory rheometry is a powerful technique used to characterize the viscoelastic properties of materials. By applying an oscillatory shear deformation, it provides insights into the material's response, allowing for the determination of critical parameters such as storage modulus, loss modulus, and complex viscosity. This method is particularly advantageous for viscoelastic adhesives as it helps in understanding their behaviour under different stress and strain conditions, which is vital for optimizing their performance in specific applications.

This document specifies a measuring method for the characterization of rheological properties of structural adhesives using oscillatory rheometry. The advantage of the method in comparison to rotational viscometry measurements lies in the separation of elastic and viscous material properties, thus allowing to define the viscoelastic properties. This enables more precise information concerning the flow behaviour of the materials, thereby resulting in a better understanding of their processing properties. The method described is particularly suitable for filled and paste-like adhesives. These are frequently processed using automated pump and application systems in industrial applications and shall be set precisely considering their rheological properties. As the rheological behaviour of uncured adhesives is mostly independent of their properties in the cured state, the standard can also serve for the examination of non-structural adhesives.
