Description

Linseed-Soybean-Tall Oil/Rosin/Phthalic/Pentaerythritol is a complex, high-performance alkyd resin intermediate or modified resin, identified by CAS No. 68334-24-7. This versatile chemical is engineered to deliver enhanced properties such as improved drying time, flexibility, and chemical resistance in final formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and polymer industries seeking to optimize product performance and durability.

Application

• Industrial Coatings Binder: A key component in the synthesis of alkyd resins for high-quality protective paints, varnishes, and enamels.
• Adhesive & Sealant Formulation: Used to impart tack, adhesion, and cohesive strength in pressure-sensitive and structural adhesive systems.
• Polymer Modification: Acts as a modifier to enhance the flexibility, gloss, and weathering resistance of various polymeric materials.
• Printing Inks: Serves as a resinous vehicle to improve ink transfer, gloss, and adhesion on various substrates.
• Marine & Corrosion-Resistant Coatings: Formulated into coatings that require excellent resistance to water, salt spray, and harsh environmental conditions.
• Wood Finishes: Used in stains, lacquers, and topcoats to provide a durable, protective finish with enhanced aesthetic qualities.

Quality Control

Our Linseed-Soybean-Tall Oil/Rosin/Phthalic/Pentaerythritol is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as acid value, viscosity, color, and solids content. Certificates of Analysis (COA) documenting these specifications 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 away from incompatible materials such as strong acids and organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent skinning or thickening.
