Description

Fatty Acids, Soya, Polymers With 1,6-Diisocyanatohexane, Pentaerythritol, Phthalic Anhydride And 3A,4,7,7A-Tetrahydro-1,3-Isobenzofurandione is a specialized polymeric resin derived from soy-based fatty acids, hexamethylene diisocyanate (HDI), pentaerythritol, phthalic anhydride, and tetrahydrophthalic anhydride. This engineered polymer offers a unique combination of flexibility, chemical resistance, and adhesion derived from its hybrid alkyd-urethane chemistry. It is essential for formulators in the coatings, adhesives, and sealants industries seeking bio-based components to enhance product performance. CAS No. 106168-22-3.

Application

• High-Performance Industrial Coatings: Used as a reactive modifier or resin in corrosion-resistant primers, topcoats, and maintenance paints for metal substrates.
• Flexible Adhesives and Sealants: Imparts flexibility and adhesion in polyurethane-based adhesive formulations for construction, automotive, and packaging applications.
• Specialty Inks: Serves as a resin component in printing inks requiring good pigment wetting, gloss, and substrate adhesion.
• Elastomer Modification: Acts as a plasticizer or compatibilizer in rubber and polyurethane elastomer compounds to adjust hardness and resilience.
• Wood Finishes: Incorporated into varnishes and stains to enhance durability, moisture resistance, and penetration.
• Composite Materials: Used as a matrix resin or additive in fiber-reinforced plastics to improve interfacial bonding and impact strength.

Quality Control

Our production of this polymeric resin adheres to strict quality management systems to ensure batch-to-batch consistency. Key parameters such as acid value, hydroxyl value, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
