Hydrogenated Rosin
Hydrogenated Rosin is produced by catalytic hydrogenation of gum or wood rosin, resulting in improved color stability, oxidative resistance, and reduced crystallization tendency compared to unmodified rosin. It is an important intermediate for producing high-quality rosin esters used as tackifiers in hot-melt adhesives, pressure-sensitive adhesives, and chewing gum bases. Its improved thermal and oxidative stability makes it suitable for demanding high-temperature adhesive applications.
