Description

4,7-Methano-1H-Indene, 3A,4,7,7A-Tetrahydro-, Polymer With 1,3-Cyclopentadiene, Cyclopentene, 1-Hexene, 2-Methyl-2-Butene And 1,3-Pentadiene is a specialized hydrocarbon resin derived from a complex co-polymerization of multiple cyclic and aliphatic olefins. This unique composition provides a versatile platform for modifying the physical and chemical properties of various industrial formulations. It is primarily sought after by manufacturers in the adhesives, sealants, coatings, and rubber compounding industries seeking to enhance tack, cohesion, and compatibility.

Application

• Hot-Melt and Pressure-Sensitive Adhesives (PSA): Acts as a key tackifier and modifier to improve adhesion, peel strength, and specific adhesion to low-energy surfaces.
• Rubber Compounding: Used as a processing aid and reinforcing resin in tire treads, belts, and other rubber goods to improve hardness, tensile strength, and abrasion resistance.
• Industrial and Protective Coatings: Imparts water resistance, improved gloss, and enhanced durability in coatings for metal, wood, and concrete.
• Sealants and Caulks: Enhances flexibility, adhesion, and weatherability in construction and automotive sealant formulations.
• Printing Inks: Serves as a resin component to improve pigment wetting, gloss, and printability in various ink systems.
• Plastic Modification: Functions as a compatibilizer or impact modifier in select polymer blends and composites.

Quality Control

Our production of this hydrocarbon resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as softening point, color, and molecular weight distribution are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperatures (15-25°C). Keep away from heat sources and open flame. For long-term storage, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain product color stability.
