• Softening point: 74-76 °C
• Acid Value KOH mg/g:  164
• Saponification Value: 5

Gum Rosin is most often used in hot melt and pressure sensitive adhesives, varnish, and printing inks.

Natural organic compound, mainly composed of resins, possesses chemical activity when dissolved in many organic solvents.
