Description

Linseed Oil, Polymer With Ethylene Glycol, Pentaerythritol, Phthalic Anhydride, Soybean Oil And Styrene CAS NO 121053-10-9 is a specialized alkyd resin copolymer designed for high-performance industrial applications. This modified resin offers a unique balance of properties derived from its combination of drying oils and synthetic components, making it a critical raw material for durable and versatile coatings. It is primarily sought by formulators in the protective coatings, industrial paints, and specialty adhesives sectors.

Application

• Industrial and Protective Coatings: Formulation of high-durability primers, enamels, and topcoats for metal substrates, machinery, and structural steel.
• Architectural Paints: Used in high-quality exterior house paints and trim paints where excellent weather resistance and gloss retention are required.
• Marine and Anti-Corrosive Paints: Key component in coatings for ships, offshore platforms, and other marine structures exposed to harsh environments.
• Wood Finishes and Varnishes: Provides a tough, flexible film for furniture finishes, floor varnishes, and other wood coating applications.
• Printing Inks: Used in the manufacture of specialty overprint varnishes and ink vehicles that require rapid drying and good adhesion.
• Specialty Adhesives and Sealants: Acts as a resin modifier to enhance flexibility, adhesion, and environmental resistance in formulated adhesives.

Quality Control

Our alkyd resin polymers are manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a series of tests including viscosity, acid value, color, solids content, and drying time. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flame. Due to its nature, the product should be stored under an inert atmosphere to prevent skinning and oxidation. Keep containers tightly sealed when not in use to prevent moisture absorption and contamination.
