Strategies for Rheological Evaluation of Adhesives
Adhesives are widely used across a broad range of industries and are a regular part of consumers’ daily lives. A quantitative understanding of the performance of such materials, such as adhesion, cohesion, tack, and peel performance is important for quality control and guiding formulators. Rheology is a powerful tool that provides direct measurement of a material’s viscoelastic properties, which correlate to their processing and end-use performance.
This webinar will discuss strategies for comprehensive rheological analysis on different kinds of adhesive materials using rotational rheometers. Specifically, we will cover flow viscosity testing, tack and peel testing, dynamic temperature ramps, and frequency sweep testing for evaluating adhesive performance, as well as creep testing for monitoring adhesive cold flow. Time-Temperature Superposition (TTS) and rheology interconversion techniques will also be covered for predicting the viscoelastic behavior over several decades of time.
