Gum Damar, also known simply as Damar resin, is a natural resin harvested from trees of the genus Shorea, primarily found in Southeast Asia. This translucent, amber-colored gum is obtained by tapping the trees and collecting the resin that oozes out. Historically, Gum Damar has been used for thousands of years across various cultures for a range of artistic, industrial, and pharmaceutical purposes. It is highly valued for its solubility in solvents, excellent adhesive properties, and long shelf life, making it an essential ingredient in numerous products.
Gum Damar is particularly prized in the art world for its role as a component in varnishes and paint mediums, while it also finds use in adhesives, incense, cosmetics, and as a binding agent in pharmaceuticals. The resin’s ability to dissolve in turpentine or other organic solvents makes it incredibly versatile, offering applications across several industries.
