Description

Rosin-Linseed Oil Copolymer is a specialized resinous polymer synthesized from natural rosin and linseed oil, offering a unique combination of tack, adhesion, and film-forming properties. This compound is valued for its ability to enhance the performance of industrial formulations, providing improved flexibility and durability. It is primarily sought by manufacturers in the adhesive, ink, coating, and sealant industries for applications requiring a renewable, resin-based modifier.

Application

• Pressure-Sensitive Adhesives (PSAs): Acts as a key tackifier and modifier to improve peel and shear strength.
• Printing Inks: Used in resin vehicles for lithographic and letterpress inks to enhance gloss, rub resistance, and drying properties.
• Protective Coatings: Incorporated into varnishes and industrial coatings to improve film flexibility, adhesion, and water resistance.
• Sealants and Caulks: Functions as a plasticizing resin to enhance workability, adhesion, and long-term elasticity.
• Rubber Compounding: Serves as a processing aid and tackifier in various rubber products.
• Hot Melt Adhesives: Provides tack and specific adhesion properties in formulations for packaging and labeling.

Quality Control

Our Rosin-Linseed Oil Copolymer is produced under a stringent quality management system. Each batch undergoes rigorous testing for key parameters including acid value, softening point, color, and viscosity to ensure consistent performance and compliance with industry specifications. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve product integrity. Keep away from heat sources and open flame.
