Technical Document

Glycerol Hydrogenated Ester Rosin is a chemically modified form of rosin, produced by esterifying hydrogenated rosin with glycerol. The hydrogenation process reduces the double bonds in the rosin, making it more stable and less prone to oxidation. The resulting ester is a pale, thermoplastic resin with enhanced adhesive properties, improved stability, and a lower acid value compared to unmodified rosin. Its structure features a balance between rigidity and flexibility, offering desirable performance characteristics in various formulations. Glycerol Hydrogenated Ester Rosin is typically supplied in solid form, often as flakes or pellets.

Glycerol Hydrogenated Ester Rosin is a versatile, chemically modified rosin produced by esterifying hydrogenated rosin with glycerol. With enhanced stability, improved adhesive properties, and a lower acid value, it is used extensively in high-performance formulations. It is a key ingredient in:

Adhesives & Sealants: Enhancing tack, bonding strength, and long-term durability in pressure-sensitive adhesives and sealants.
Coatings & Printing Inks: Improving film formation, gloss, and stability in both solvent-based and waterborne coating systems, while resisting oxidation and thermal degradation.
Rubber & Polymer Formulations: Acting as a compatibilizer and tackifier to boost processing performance and mechanical properties in rubber compounds and polymer blends.
