What is it?
Natural resin is a product which comes from a plant or tree exudate. A resin is slight sticky or gummy yellow or gold product that eventually hardens over time. Resins have a strong odor often caused by the terpenes contained in the natural product. In industry, resins may be used as varnishes, paints, sealants, lacquers, and adhesives.
