Description

Tall-Oil Rosin, Maleated, Polymer With Dicyclopentadiene is a high-performance, modified rosin derivative engineered for enhanced thermal stability and adhesion. This specialized polymer is crucial for formulators seeking to improve the durability, tack, and chemical resistance of their products. It is primarily needed by manufacturers in the adhesives, printing inks, coatings, and rubber compounding industries for demanding applications.

Application

• Hot-Melt Adhesives (HMA): Acts as a key tackifier and modifier, improving adhesion to various substrates and thermal stability.
• Pressure-Sensitive Adhesives (PSA): Enhances peel strength, tack, and shear resistance in tapes and labels.
• Rubber Compounding: Used as a processing aid and reinforcing resin to improve hardness, tensile strength, and aging properties.
• Printing Inks: Serves as a resinous component to enhance gloss, rub resistance, and pigment wetting, particularly in gravure and flexographic inks.
• Industrial Coatings: Improves film hardness, chemical resistance, and drying characteristics.
• Sealants and Caulks: Provides enhanced flexibility, adhesion, and durability.
• Road Marking Paints: Contributes to fast-drying properties and long-term durability under traffic and weather exposure.

Quality Control

Our Tall-Oil Rosin, Maleated, Polymer With Dicyclopentadiene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of acid value, softening point, color, and viscosity. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee compliance with agreed specifications.

Storage

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