The Chemistry of Tackifying Resins - Part III

SpecialChem / Mar 26, 2003

Resins are low molecular weight amorphous polymers. Their main applications are in adhesives, inks, and chewing gum. In adhesives, resins are used to generate tack and specific adhesion. Mostly they are used together with larger polymers, which form the backbone of the adhesive and thus generate cohesion. Formulators use resins to create the best balance between adhesion and cohesion. There are many different resins available to the marketplace. Tackifying resins can be divided into three groups: hydrocarbon resins, rosin resins and terpene resins. Hydrocarbon resins are based on a petroleum feedstock, i.e., a synthetic source, rosin resins are based on a natural feedstock: gained from pine trees and terpene resins are generated from a natural source, wood turpentine or from the kraft sulphate pulping process. There are various physical and chemical parameters that are important to characterize tackifier resins. For hydrocarbon tackifier resins the aromatic/aliphatic balance of the resin is of special interest to adhesive formulators since it largely determines compatibility and ultimately, adhesive performance.
