Description

Rosin, Fumarated, Polymer With Trimethylolethane is a high-performance, modified rosin ester resin designed for advanced industrial applications. This specialized polymer offers enhanced thermal stability, improved adhesion, and excellent compatibility with a wide range of polymers and solvents. It is a critical raw material for formulators in the coatings, adhesives, and ink industries seeking to develop high-quality, durable products with specific performance characteristics.

Application

• Hot-Melt Adhesives (HMA): A key tackifier and modifier, providing excellent initial tack, adhesion to non-polar substrates, and thermal stability for packaging, woodworking, and product assembly adhesives.
• Industrial and Protective Coatings: Used as a resin modifier to enhance film hardness, gloss, water resistance, and drying speed in solvent-based and high-solid coatings.
• Printing Inks: Serves as a versatile resin for gravure, flexographic, and lithographic inks, improving pigment wetting, gloss development, and substrate adhesion.
• Pressure-Sensitive Adhesives (PSA): Functions as an effective tackifying resin in solvent-based, water-based, and hot-melt PSA formulations for labels, tapes, and graphic films.
• Rubber Compounding: Acts as a processing aid and tackifier, improving the compoundability and green strength of various rubber formulations.
• Sealants and Caulks: Imparts improved adhesion, cohesion, and flexibility in formulations designed for construction and automotive applications.

Quality Control

Our Rosin, Fumarated, Polymer With Trimethylolethane is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including assessment of acid value, softening point, color, and solubility. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment to guarantee product integrity and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent contamination and minimize exposure to moisture.
