Description

Linseed Oil, Polymer With Isophthalic Acid And Trimethylolethane is a specialized alkyd resin derived from natural linseed oil, modified with isophthalic acid and the polyol trimethylolethane. This chemical synthesis creates a high-performance polymer resin valued for its excellent durability, adhesion, and flexibility in coating formulations. It is primarily sought after by manufacturers in the protective coatings, industrial paints, and specialty ink industries seeking to enhance product performance with a bio-based component.

Application

• As a primary film-forming resin in high-quality industrial and maintenance paints.
• In the formulation of corrosion-resistant primers and topcoats for metal substrates.
• As a modifying resin in printing inks to improve gloss, adhesion, and rub resistance.
• In wood coating systems, including varnishes and stains, for enhanced penetration and protection.
• As a component in specialty coatings for automotive, agricultural, and marine applications.
• In the production of air-drying or force-drying alkyd enamels with good weathering properties.

Quality Control

Our Linseed Oil, Polymer With Isophthalic Acid And Trimethylolethane is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as acid value, viscosity, solids content, and color to ensure consistent performance in your formulations. 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 heat sources and open flames. 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 skinning and oxidation.
