Description

Linseed Oil, Polymer With Isophthalic Acid And Pentaerythritol is a high-performance, synthetic alkyd resin derived from natural linseed oil, modified with isophthalic acid and pentaerythritol. This chemical modification yields a polymer with superior durability, excellent adhesion, and enhanced resistance to weathering and chemicals compared to standard linseed oil. It is a critical raw material for industrial formulators seeking to produce high-quality, long-lasting protective coatings and inks. The product is identified by CAS No. 67989-61-1.

Application

• Industrial Coatings: As a primary resin binder in high-performance protective coatings for metal structures, machinery, and automotive primers.
• Architectural Paints: Used in the formulation of durable exterior house paints, trim enamels, and varnishes requiring excellent gloss retention and flexibility.
• Printing Inks: Serves as a key component in specialty printing inks, including overprint varnishes and packaging inks, for its fast-setting and film-forming properties.
• Wood Finishes: An essential ingredient in high-grade wood stains, sealers, and furniture finishes, providing deep penetration and a hard, protective film.
• Marine Coatings: Formulated into anti-corrosive paints and finishes for ships and offshore structures due to its water resistance and adhesion to damp surfaces.
• Adhesives & Sealants: Used as a tackifier and film-forming agent in certain industrial adhesive and sealant formulations.

Quality Control

Our Linseed Oil, Polymer With Isophthalic Acid And Pentaerythritol is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for critical parameters such as acid value, viscosity, solids content, color, and drying time to ensure consistent performance and compliance with industry specifications. Certificates of Analysis (COA) documenting these results 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 flame. 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.
