A study by University of Ottawa’s Department of Chemical Engineering entitled, “The Effect of Particle Size And Composition on The Performance of Styrene/Butyl Acrylate Miniemulsion-Based PSAs”, discussed how the control over particle sizes afforded by miniemulsions could enable us to affect the properties of pressure-sensitive adhesives (PSAs) in a controlled manner.
In this particular study, particle size was found to be the most influential factor for the form models. To determine accurate particle size and particle size distribution (PSD) measurements, the researchers from the University of Ottawa used Brookhaven’s disc centrifuge photosedimentometer (BI-DCP). These accurate measurements were able to help the researchers deduce that the positive effect of smaller particles on every adhesive property related to the tighter packaging thus, increasing the area of contact between the adhesive and the substrate.
The approach used in this work is significant as it could easily be adapted to study other factors influencing PSA properties. To achieve accuracy with their studies, scientists and researchers use only high-quality disc centrifuge instruments. The BI-DCP is among Brookhaven Instruments’ line of effective and efficient equipment.
