Polymerized Rosin 140 (Granular) is a high‑performance modified resin with a softening point of 135‑145℃, featuring high viscosity and anti‑crystallization properties. It has a light color, strong oxidation resistance and low yellowing tendency, and shows excellent compatibility with various film‑forming agents and rubbers.

In the ink industry, its modified form can improve the fast‑setting and high‑gloss properties of offset inks, and greatly enhance the adhesion and corrosion resistance of tin‑printing inks. When aminated for coatings, it can be formulated into fast‑drying water‑based coatings that form bright, water‑resistant films. It is also suitable for investment casting, electronic encapsulation, pigment surface treatment and other applications.
