Description

Rosin Oil No 1 is a specialized derivative of pine rosin, processed to produce a pale, viscous oil with excellent solvency and tackifying properties. This product is valued for its ability to enhance adhesion, flexibility, and water resistance in various formulations, making it a critical component in industrial manufacturing. It is primarily utilized by producers in the adhesives, rubber compounding, printing inks, and surface coating industries seeking reliable, high-performance raw materials.

Application

• Adhesive Formulations: Acts as a key tackifier and plasticizer in hot-melt, pressure-sensitive, and rubber-based adhesives.
• Rubber Compounding: Used as a processing aid and softener to improve the plasticity and workability of natural and synthetic rubber.
• Printing Inks: Serves as a resinous vehicle and gloss improver in lithographic and gravure inks.
• Surface Coatings & Paints: Imparts flexibility, adhesion, and water resistance to protective coatings and varnishes.
• Foundry Core Binders: Functions as a binder resin in sand cores for metal casting.
• Paper Sizing: Used in the internal and surface sizing of paper to improve strength and water repellency.
• Sealants and Caulks: Provides tack and body to non-hardening sealing compounds.

Quality Control

Our Rosin Oil No 1 is manufactured under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through a series of analytical tests including color, acid value, viscosity, and solubility. A Certificate of Analysis (COA) documenting these parameters is provided with every shipment to guarantee the product meets your specified requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and 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 oxidation and thickening.
