Description

Copal Gum CAS NO 9000-14-0 is a natural resin derived from various tropical trees, valued for its excellent film-forming properties, hardness, and chemical resistance. It serves as a crucial raw material in the formulation of high-performance coatings, adhesives, and inks, providing durability and gloss. This product is essential for manufacturers in the paint & coatings, printing, and specialty chemical industries seeking sustainable, natural resin solutions.

Application

• Coatings and Varnishes: As a primary film-forming agent in high-gloss, protective wood and metal finishes.
• Printing Inks: Used to enhance the gloss, rub resistance, and drying properties of lithographic and flexographic inks.
• Adhesives and Sealants: Acts as a tackifier and binder to improve adhesion strength and cohesion in industrial and construction adhesives.
• Lacquers: A key component in the formulation of durable, quick-drying lacquers for furniture and automotive applications.
• Artists' Materials: Employed in the production of high-quality oil paints, picture varnishes, and restoration compounds.
• Encapsulation and Potting Compounds: Provides electrical insulation and environmental protection in electronic applications.
