Description

Coumarone Resin CAS NO 63393-89-5 is a thermoplastic resin derived from the polymerization of coumarone and indene, typically obtained from coal tar fractions. This versatile resin is valued for its excellent water resistance, good electrical insulation properties, and compatibility with a wide range of polymers, rubbers, and waxes. It is an essential component for formulators and manufacturers in the adhesives, rubber compounding, coatings, and printing ink industries seeking to enhance product performance and durability.

Application

• Adhesive Formulations: Acts as a tackifier and modifier in hot-melt, pressure-sensitive, and rubber-based adhesives to improve bond strength and flexibility.
• Rubber Compounding: Used as a processing aid, softener, and reinforcing agent in tire manufacturing and other rubber goods to enhance extrusion and mold flow.
• Coatings and Paints: Imparts water resistance, gloss, and durability to industrial paints, varnishes, and marine coatings.
• Printing Inks: Serves as a binder and glossing agent in gravure and flexographic inks, improving rub resistance and print quality.
• Flooring and Linoleum: Functions as a plasticizer and binder in the production of floor tiles and linoleum products.
• Electrical Insulation: Utilized in cable compounds and insulating tapes due to its good dielectric properties.
• Waterproofing Compounds: A key ingredient in sealants, caulks, and waterproofing membranes for construction.
• Foundry Core Binders: Employed as a binding agent in sand cores for metal casting.
