Description

Soybean Oil, Polymer With Isophthalic Acid, Pentaerythritol And Terephthalic Acid CAS NO 68072-22-0 is a specialized alkyd resin derived from modified soybean oil, offering a sustainable and versatile polymeric backbone. This product matters for formulators seeking high-performance, bio-based components that enhance flexibility, adhesion, and durability in coatings and composites. It is primarily needed by manufacturers in the paints & coatings, adhesives, and industrial resin sectors who require reliable, high-quality polymeric raw materials.

Application

• Industrial and Protective Coatings: Used as a film-forming agent in alkyd-based paints, primers, and varnishes for metal, wood, and concrete substrates.
• Adhesives and Sealants: Serves as a key polymeric component to improve flexibility, tack, and environmental resistance.
• Printing Inks: Acts as a resin binder in specialty inks, contributing to gloss, rub resistance, and substrate adhesion.
• Composite Materials: Utilized as a matrix modifier or cross-linking agent in fiber-reinforced plastics and laminates.
• Caulks and Putties: Enhances the workability, durability, and weather resistance of non-hardening sealants.

Quality Control

Our Soybean Oil Polymer is produced under strict quality management protocols to ensure batch-to-batch consistency and performance. Each lot undergoes rigorous testing for key parameters such as acid value, viscosity, and color. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen blanket) to preserve product integrity. Keep away from heat sources and open flames.
