Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Azelaic Acid, Diethylene Glycol, Isophthalic Acid, Maleic Anhydride And Trimethylolpropane is a high-performance, synthetic polyester resin designed for demanding industrial applications. This complex polymer offers exceptional durability, chemical resistance, and formulation flexibility, making it a critical component for advanced material science. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance and longevity.

Application

• High-Performance Industrial Coatings: Used as a binder in alkyd resins for protective coatings, marine paints, and corrosion-resistant finishes.
• Adhesives and Sealants: Serves as a key polymeric backbone providing strong adhesion, flexibility, and environmental stability.
• Elastomers and Rubber Modifiers: Imparts improved tensile strength, elasticity, and aging resistance to synthetic rubber compounds.
• Inks and Overprint Varnishes: Enhances gloss, abrasion resistance, and drying properties in specialty printing applications.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics and other composite systems.
• Plasticizers and Additives: Functions as a polymeric plasticizer to improve the flexibility and processability of rigid polymers like PVC.

Quality Control

Our production of this specialty polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including acid value, hydroxyl value, viscosity, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with global regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as 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 moisture absorption and skin formation.
