Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Neopentyl Glycol, Phthalic Anhydride And Trimethylolpropane is a synthetic resin derived from unsaturated C18 fatty acid dimers and trimers, polymerized with polyols and phthalic anhydride. This compound is valued for its excellent film-forming properties, flexibility, and chemical resistance, making it a crucial component in high-performance coatings. It is primarily sought after by formulators in the paints, coatings, and adhesives industries seeking to enhance product durability and application characteristics.

Application

• As a primary resin or modifying agent in alkyd coatings for industrial and architectural applications.
• Formulation of high-quality, flexible protective coatings for metal, wood, and plastic substrates.
• Production of adhesives and sealants requiring good adhesion and environmental resistance.
• Manufacture of printing inks, where it contributes to gloss, flow, and substrate wetting.
• Use in can and coil coatings that demand excellent formability and corrosion protection.
• As a modifier in synthetic lubricants and grease formulations to improve viscosity and stability.

Quality Control

Our production of this alkyd resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. Certificates of Analysis (COA) documenting these specifications are available upon request to support your formulation and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent skinning or moisture absorption.
