SPECIFICATION APPEARANCE light yellow MELTING POINT°C 76 min ACIDITY(mg KOH/g) 166 min UN SAP VALUE% 5.0 max INSOLUBLES (in alcohol) % 0.05 max ASH % 0.02 max Application: Gum rosin can be dissolved easily in many organic solvents and has special chemical activity.It is an important raw material for the production of paper, coatings, inks, rubber, soaps, electronic industrial products, food grade ester gum, and rosin ester resins. Stored: Stored in a cool, ventilated, dry storehouse, far from fire, heat, and preventing it from sunlight exposure. In ordert to prevent it becoming darker in color and performance changes ,Rosin is best storage in block, because it is very sensitive in oxygen especially when is in powder.
