What is a Phenolic Resin in an ink?
Phenolic Resins provide crucial printed film properties like gloss, rub and setting, and together with Hydro Carbon Resins (resins based on oil fractions), provide the carrier for pigments. Phenolic Resin is a further evolutionary development of Gum Rosin where it is reacted with phenols to provide a high performance resin to suit the latest press, consumable and market demand. For offset printing Phenolic Resin is the engine that drives the technological excellence to provide the performance at the highest press speeds and most challenging quality demands. The usage of both phenolic and hydrocarbon resin are essential and optimised to deliver the required performance for the printing process. Another alternative for Gum Rosin based Phenolic Resins are Tall Oil based Phenolic Resins. Flint Group is very experienced in using Phenolic Resins based on Tall Oil which is produced during paper production. In North America inks are traditionally based on Tall-Oil Phenolic Resin, but unfortuna
