Description

Rosin, Polymer With Dicyclopentadiene, Maleic Anhydride And Tung Oil is a specialized, high-performance modified rosin resin designed for demanding industrial applications. This unique polymer combines the excellent adhesion and tackifying properties of rosin with the enhanced thermal stability and water resistance imparted by dicyclopentadiene, maleic anhydride, and tung oil. It is a critical raw material for formulators seeking to improve the durability and performance of coatings, adhesives, and inks. Key industries that rely on this advanced resin include the paints & coatings, adhesive manufacturing, and printing ink sectors.

Application

• High-Performance Industrial Coatings: Used as a modifying resin in alkyd and phenolic-based coatings for metal, wood, and concrete, providing improved hardness, gloss, and chemical resistance.
• Hot-Melt and Pressure-Sensitive Adhesives (PSA): Acts as a primary tackifier and modifier, enhancing adhesion strength, thermal stability, and cohesive properties.
• Printing Inks: Serves as a key component in gravure, flexographic, and lithographic inks, contributing to gloss, rub resistance, and pigment wetting.
• Rubber Compounding: Utilized as a processing aid and tackifier in rubber products to improve compound viscosity and green strength.
• Sealants and Caulks: Incorporated to enhance adhesion, flexibility, and weatherability in construction and automotive sealant formulations.
• Paper Sizing: Employed in internal and surface sizing to improve water resistance and printability of paper and paperboard.

Quality Control

Our production of Rosin, Polymer With Dicyclopentadiene, Maleic Anhydride And Tung Oil adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized by key parameters including acid value, softening point, color, and viscosity. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We are committed to meeting the quality standards required by the coatings, adhesives, and ink industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., nitrogen blanket) in the container headspace is recommended to preserve product integrity. Keep away from heat sources and open flames.
