Gum Rosin is a marvel of nature, a pristine resin extracted with care from the sap of pine trees. Celebrated for its eco-friendly essence, this non-toxic and biodegradable gem transforms into a light yellow to transparent solid, softly exuding a subtle pine aroma. Boasting a density of 1.07-1.09g/cm³ and a softening point between 70-85ºC, it stands as a testament to natural brilliance. With an acid value of about 150-180mg KOH/g, this resin dazzles with its exceptional solubility in organic solvents such as ethanol and acetone, while remaining insoluble in water. Choose Gum Rosin for a sustainable, effective solution.
