Description

4,7-Methano-1H-Indene, 3A,4,7,7A-Tetrahydro-, Polymer With Ethenylmethylbenzene, 1H-Indene And (1-Methylethenyl)Benzene is a high-performance hydrocarbon resin derived from a complex copolymerization of specific indene and aromatic monomers. This product matters for its ability to impart excellent tack, adhesion, and compatibility in demanding formulation systems, offering a balance of properties not easily achieved with simpler resins. It is primarily needed by manufacturers in the adhesive, sealant, rubber compounding, and specialty coating industries seeking to enhance product performance and durability.

Application

• Hot-Melt and Pressure-Sensitive Adhesives (PSA): Functions as a key tackifying resin to improve initial grab, peel strength, and overall adhesion performance.
• Rubber Compounding: Used as a processing aid and reinforcing agent in tire manufacturing and industrial rubber goods to enhance hardness, tensile strength, and abrasion resistance.
• Sealants and Caulks: Improves cohesion, flexibility, and weather resistance in construction and automotive sealant formulations.
• Printing Inks: Acts as a hard resin to improve gloss, rub resistance, and drying characteristics in specialty ink applications.
• Industrial and Protective Coatings: Enhances film hardness, chemical resistance, and durability in solvent-based coating systems.
• Polymer Modification: Employed as a compatibilizer or modifier to tailor the properties of other polymers, including SBS, SIS, and EVA.
