Gum Rosin

Description

What is Gum Rosin?

Gum Rosin, also known as colophony, is a natural solid resin obtained from pine trees. It is produced by distilling pine resin to remove the volatile turpentine oil, leaving behind a translucent, brittle, and glassy solid. Gum Rosin ranges in color from pale yellow to deep amber and is widely used as a raw material in adhesives, coatings, inks, rubber, and various other industrial applications due to its tackiness and chemical reactivity.
