Impact of Tackifier content on Pressure-Sensitive Adhesive based on acrylicpolymer

The purpose of this study was to examine how different levels of tackifier content (specifically rosin ester(RS)) affect key characteristics of an acrylic PSA, including tack, peel, and shear strength. A PSA derivedfrom acrylate was produced for the experiment, with varying amounts of tackifier incorporated into theformulation. The findings suggest that RS may exhibit the highest level of compatibility with the synthesizedPSA. Interestingly, the inclusion of ۲ wt % of RS resulted in notable alterations in the tack and peel propertiesof the PSA; nevertheless, it led to a considerable decrease in shear strength.
