Polymerized rosin is a modified product of rosin polymerization. It matches well with alkyd, phenolic resins, and vegetable oils, featuring core properties like a high softening point, anti-oxidation, anti-crystallization, and good compatibility. It's also low in VOCs and oil-soluble, making it widely used in paints, inks, adhesives, and water-based coatings. In paints, its modified resin makes the film hard, glossy, resistant to yellowing, and water-resistant, and after amination, it can be used to make quick-drying water-based paints. In inks, it's a key ingredient in offset inks, helping them dry fast, have high gloss, and excellent printability. It can also improve the adhesion and gloss of flexographic inks, boost the metal adhesion and corrosion resistance of tinplate inks, meeting high-end printing needs.
