Description

Linseed Oil, Polymer With Dicyclopentadiene CAS NO 68213-53-6 is a specialized, high-performance modified alkyd resin derived from natural linseed oil and dicyclopentadiene (DCPD). This polymerization creates a product with enhanced drying properties, chemical resistance, and durability compared to conventional linseed oil. It is a critical raw material for formulators in the coatings and polymer industries seeking to improve the performance and sustainability profile of their products. Key applications include high-quality industrial paints, varnishes, and specialty resin systems.

Application

• Industrial Coatings Binder: Used as a primary resin in air-drying alkyd paints and enamels for machinery, agricultural equipment, and structural steel, offering excellent gloss retention and durability.
• Protective Varnishes and Wood Finishes: Serves as a key component in clear and pigmented varnishes for wood, providing a hard, protective film with good water and alkali resistance.
• Printing Ink Vehicles: Acts as a modified resin vehicle in specialty printing inks, contributing to rapid setting, gloss, and adhesion on various substrates.
• Adhesive and Sealant Formulations: Incorporated into adhesive and sealant systems to enhance flexibility, adhesion, and environmental resistance.
• Corrosion-Resistant Primer Formulation: Utilized in primers for metal substrates, where its polymer structure promotes adhesion and provides a barrier against corrosion.
• Specialty Polymer Modifier: Functions as a reactive modifier or plasticizer in other polymer systems to improve specific properties like impact strength or weatherability.

Quality Control

Our Linseed Oil, Polymer With Dicyclopentadiene is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as viscosity, acid value, color, and solids content. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and formulation processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. Under these conditions, the product has a typical shelf life of 12-24 months from the date of manufacture.
