Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Benzoic Acid, Maleic Anhydride, Neopentyl Glycol, Phthalic Anhydride, 1-Tridecanol And Trimellitic Anhydride is a complex, high-performance polymeric resin synthesized from a blend of unsaturated fatty acid dimers and key monomers. This product matters because it is engineered to deliver exceptional durability, chemical resistance, and adhesion properties in demanding industrial coatings and adhesives. It is primarily needed by formulators in the paints & coatings, printing inks, and specialty adhesive industries seeking to enhance product performance and longevity.

Application

• High-Performance Industrial Coatings: Used as a key resin binder in alkyd and polyester formulations for heavy-duty machinery, automotive primers, and marine coatings.
• Printing Inks: Serves as a vital component in resin vehicles for offset and gravure inks, providing excellent gloss, rub resistance, and pigment wetting.
• Specialty Adhesives & Sealants: Imparts flexibility, water resistance, and strong substrate adhesion in construction and assembly adhesives.
• Corrosion-Resistant Primers: Formulated into primers for metal substrates, offering enhanced barrier protection against moisture and chemicals.
• Plasticizers & Modifiers: Acts as a polymeric modifier to improve the flexibility and impact resistance of other rigid resin systems.
• Wood Finishes: Incorporated into varnishes and stains to improve film formation, drying time, and durability.

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 solids content are strictly monitored. Certificates of Analysis (COA) documenting these specifications 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, and well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as organic solvents. The product has a typical shelf life of 24 months when stored under these conditions.
