Rosin Glyceryl Ester
Rosin glycerol ester, also known as 138# resin, is an irregular light yellow granular or flaky transparent solid formed by the esterification of rosin and glycerol under the action of a catalyst.
Performance and Applications:
This product is completely soluble in ester solvents, petroleum-based solvents, and turpentine, but insoluble in alcohol solvents. It features a light color, resistance to yellowing, and strong adhesion. This product significantly improves the initial tack of EVA hot melt adhesives and enhances the tack strength of difficult-to-bond materials, while also uniquely improving the cold resistance of adhesives. In paint applications, it exhibits water resistance, durability, and gloss, making it suitable for industries such as adhesives, laminating adhesives, glue sticks, inks, coatings, waxed paper, and electrical equipment.
