Hydrogenated Rosin (Alcohol-Soluble) is an extremely light-colored polyol rosin developed through processes including hydrogenation, esterification, and stabilization, using refined rosin as the base material. It offers advantages such as water-white appearance, excellent aging resistance, and good compatibility with polymer materials, meeting the specialized requirements of the adhesive industry. It finds extensive applications in high-grade flux, solder paste, colorless adhesives, coatings, in
