Description

Isophthalictrimethylolethane-Soybeanoilpolymer is a specialized polymeric resin derived from the reaction of isophthalic acid, trimethylolethane, and soybean oil. This unique composition provides a versatile platform for formulating high-performance, bio-based materials with excellent durability and chemical resistance. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty plastics industries seeking sustainable and high-quality polymer solutions.

Application

• Alkyd Resin Modifier: Used to enhance the flexibility, drying time, and adhesion properties of alkyd-based surface coatings and paints.
• Bio-based Coating Formulations: Serves as a key component in the production of environmentally friendly industrial and architectural coatings.
• Adhesive and Sealant Systems: Imparts toughness and chemical resistance to high-performance adhesive and sealant products.
• Plasticizer and Stabilizer: Acts as a polymeric plasticizer and stabilizer in various plastic and rubber compounding applications.
• Printing Ink Binder: Utilized as a binder in specialty printing inks to improve gloss, rub resistance, and film properties.
• Industrial Maintenance Paints: A vital ingredient in heavy-duty maintenance paints for metal and concrete surfaces requiring strong acid and solvent resistance.

Quality Control

Our Isophthalictrimethylolethane-Soybeanoilpolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including checks for acid value, viscosity, color, and solid content. Certificates of Analysis (COA) documenting full 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 strong acids and organic solvents. 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 skin formation or contamination.
