Description

Rosin, Fumarated, Polymer With Sorbitol is a chemically modified rosin ester, specifically a polymer of fumarated rosin and sorbitol. This compound is valued for its excellent film-forming, adhesive, and tackifying properties, making it a crucial component in high-performance industrial formulations. It is primarily sought by manufacturers in the adhesives, coatings, printing inks, and polymer modification industries seeking to enhance product durability and performance.

Application

• Hot-Melt Adhesives (HMAs): Acts as a key tackifier and viscosity modifier, improving adhesion and open time.
• Pressure-Sensitive Adhesives (PSAs): Provides essential tack and peel strength for labels, tapes, and graphic films.
• Industrial and Protective Coatings: Used as a resin modifier to enhance gloss, hardness, and water resistance.
• Printing Inks: Serves as a resinous vehicle to improve pigment wetting, gloss, and rub resistance.
• Polymer Modification: Functions as a processing aid and compatibilizer in various polymer blends.
• Sealants and Caulks: Imparts flexibility, adhesion, and durability to formulations.

Quality Control

Our Rosin, Fumarated, Polymer With Sorbitol is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistency in key parameters such as acid value, softening point, color, and viscosity. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee reliable performance in your formulations.

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). This material is easily oxidized; prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability. Keep away from heat sources and open flame.
