Description

Linseed Oil, Polymer With 3-Hydroxy-2-(Hydroxymethyl)-2-Methylpropanoic Acid, Isophthalic Acid, Pentaerythritol, Phthalic Anhydride And Trimethylolpropane CAS NO 125471-96-7 is a specialized, high-performance alkyd resin derived from natural and synthetic components. This engineered polymer is valued for its excellent film-forming properties, durability, and chemical resistance, making it a critical raw material for advanced coating formulations. It is primarily sought by manufacturers in the industrial coatings, printing inks, and specialty adhesives sectors seeking to enhance product performance and sustainability profiles.

Application

• Industrial and Protective Coatings: As a primary resin binder in high-performance coatings for metal, wood, and concrete, offering excellent weather resistance and adhesion.
• Printing Inks: Used in the formulation of specialty inks, including overprint varnishes and packaging inks, for superior gloss and rub resistance.
• Adhesives and Sealants: Serves as a key component in structural and elastic adhesives, providing strong bonding and flexibility.
• Automotive Finishes: Incorporated into primer and topcoat formulations for enhanced durability and aesthetic finish.
• Marine Coatings: Utilized in anti-corrosive paint systems for ships and offshore structures due to its resistance to saltwater and humidity.
• Wood Finishes: A vital ingredient in varnishes and stains, delivering deep penetration, protection, and a durable finish.
• Artists' Paints and Mediums: Employed in high-quality oil-based artist paints and painting mediums for controlled drying and film integrity.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. Quality is monitored against key parameters including acid value, viscosity, solids content, color, and drying time to guarantee batch-to-batch consistency and performance in your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat sources, open flames, and incompatible materials such as strong acids and organic solvents. Under recommended storage conditions, the product is typically stable.
