HY Series Dimer Acid – High-Purity Dicarboxylic Fatty Acid for Industrial Formulations

The HY Series Dimer Acid is a high-performance, multi-functional dicarboxylic acid widely used in the production of specialty polymers, epoxy curing agents, coatings, adhesives, and lubricant intermediates. Produced through controlled dimerization of unsaturated fatty acids, this series offers consistent chemical structure, excellent thermal resistance, and flexible formulation properties ideal for demanding industrial applications.

Product Highlights

• High Acid and Saponification Values: Acid values exceed 190 mgKOH/g and saponification values are over 192 mgKOH/g, ensuring strong chemical reactivity and performance in polyester and polyamide synthesis.
• Excellent Thermal Stability: With a flash point above 260°C, the HY Series Dimer Acid supports safe use in high-temperature processing environments.
• Color Stability for Critical Applications: Gardner color values ranging from 5 to 8 make this product suitable for clear or color-sensitive resin, coating, and ink formulations.
• Wide Viscosity Range: Available viscosities from 800 to 8500 mPa·s (at 25°C) allow formulators to select the ideal grade for flexibility, film strength, and flow characteristics.

Industrial Applications

• Polyamide Resins and Hot-Melt Adhesives: Enables improved flexibility, adhesion, and thermal resistance.
• Epoxy Resin Curing Agents: Contributes to enhanced chemical resistance and toughness in coatings and composites.
• Coatings and Inks: Offers low color and high pigment dispersion, ideal for high-performance surface applications.
• Lubricants, Emulsifiers, and Surfactants: Functions as a key intermediate in manufacturing biodegradable, high-performance specialty chemicals.
