Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Maleicanhydride, Phthalic Anhydride And Trimethylolpropane is a high-performance, synthetic resin intermediate derived from unsaturated C18 fatty acid dimers. This compound matters for its ability to impart excellent flexibility, adhesion, and chemical resistance when incorporated into polymer systems. It is primarily needed by formulators in the coatings, adhesives, and ink industries seeking to enhance the durability and performance of their final products.

Application

• Alkyd Resin Modifier: Used to improve flexibility, gloss retention, and drying properties in industrial and decorative coatings.
• Adhesive Formulation: Serves as a key component in pressure-sensitive and structural adhesives to enhance tack and bond strength.
• Printing Ink Binder: Imparts rub resistance and substrate adhesion in high-performance paste and liquid inks.
• Corrosion-Resistant Coatings: A building block for resins used in protective primers and topcoats for metal substrates.
• Plasticizer & Stabilizer: Acts as a secondary plasticizer and stabilizer in certain polymer compositions to improve processing and longevity.
• Industrial Maintenance Paints: A critical raw material for resins used in heavy-duty marine, machinery, and architectural paints.

Quality Control

Our production of this resin intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, viscosity, and color are rigorously monitored. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and formulation processes.

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 bases 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.
