Description

Fatty Acids, C16-18 And C18-Unsatd., Polymers With Phthalic Anhydride And Trimethylolpropane is a synthetic polymeric resin derived from specific fatty acids, phthalic anhydride, and trimethylolpropane. This compound is engineered to provide excellent film-forming properties, flexibility, and adhesion, making it a crucial intermediate for high-performance surface coatings. It is primarily sought after by formulators in the paints, inks, and industrial coatings industries who require durable, alkyd-type resin backbones.

Application

• Primary resin component in the formulation of alkyd-based industrial paints and protective coatings.
• Key intermediate for manufacturing high-gloss decorative paints and architectural coatings.
• Binder in specialty printing inks, offering good pigment wetting and gloss.
• Modifier for adhesives and sealants to enhance flexibility and adhesion to various substrates.
• Base polymer for corrosion-resistant metal primers and maintenance coatings.
• Raw material in the production of synthetic lubricants and grease thickeners.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters such as acid value, viscosity, color, and hydroxyl value are strictly monitored. Certificates of Analysis (COA) 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 alkalis 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.
