Description

C36 Dimer Acid is a high-purity, long-chain dicarboxylic acid derived from unsaturated fatty acids, primarily oleic acid. This versatile chemical intermediate is valued for its excellent thermal stability, flexibility, and compatibility with a wide range of polymers and resins. It is an essential raw material for manufacturers in the coatings, adhesives, lubricants, and polymer industries seeking to enhance product performance and durability.

Application

• Polyamide Resins: A key monomer for producing non-reactive, thermoplastic polyamide hot-melt adhesives with excellent flexibility and adhesion.
• Corrosion Inhibitors: Used in the formulation of high-performance rust preventatives and lubricant additives for metalworking fluids.
• Epoxy Curing Agents & Modifiers: Imparts improved flexibility, impact resistance, and chemical stability to cured epoxy systems.
• Synthetic Lubricants: Serves as a base fluid or viscosity modifier for high-temperature, biodegradable lubricants and greases.
• Alkyd Resins: Modifies alkyd coatings to improve drying time, gloss retention, and weatherability.
• Polyester Polyols: Used in the synthesis of polyols for flexible and rigid polyurethane foams, elastomers, and coatings.
• Printing Inks: Acts as a modifier in resin vehicles to enhance pigment wetting, flow, and final film properties.
• Personal Care & Cosmetics: Employed as an emollient and thickening agent in creams, lotions, and makeup products.

Quality Control

Our C36 Dimer Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for acid value, color, viscosity, and composition. Certificates of Analysis (COA) are provided with every shipment, and we support compliance with relevant global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids, oxidizing agents, and heat sources. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize exposure to moisture and air.
