Applications

Lubricant Industry

• Dimer acid plays a vital role in the lubricant industry as a key intermediate for the synthesis of various synthetic esters and polyamide-based lubricants. Its long-chain dicarboxylic structure provides superior lubricity, low volatility, and high thermal stability. These characteristics make it particularly suitable for high-temperature and high-load applications such as industrial gear oils and compressor lubricants.
• In addition to its lubricating performance, dimer acid contributes to oxidation resistance and corrosion protection, effectively extending the service life of lubricants. It also enhances viscosity stability, ensuring consistent performance under extreme pressure and temperature. In aviation and automotive lubricants, dimer acid esters are widely used for their excellent film-forming ability and oxidative stability, providing smooth operation and reduced wear in demanding mechanical environments.

Coating and Resin Industry

• In the coating and resin industry, dimer acid is primarily used to produce polyamide resins, epoxy curing agents, and alkyd resins. Its flexible molecular backbone and hydrophobicity give coatings superior adhesion, toughness, and water resistance. Dimer acid polyamide resins are extensively used in industrial coatings, can coatings, and packaging films where they enhance gloss, flexibility, and surface protection.
• As a component in epoxy systems, dimer acid functions as a flexible curing agent that reduces brittleness while improving the impact resistance of the coating. In environmentally friendly water-based and powder coatings, dimer acid helps lower VOC emissions and enhances compatibility with bio-based resins, aligning with current sustainability trends in the coatings industry.

Adhesive and Sealant Industry

• Dimer acid is an important raw material in the formulation of polyamide hot-melt adhesives and pressure-sensitive adhesives. Its long aliphatic chain structure offers excellent flexibility, adhesion, and water resistance. Dimer acid-based adhesives are particularly suitable for applications involving metals, plastics, and textiles, where strong bonding and thermal endurance are required.
• In sealant formulations, dimer acid provides elasticity and weather resistance, allowing sealing materials to maintain performance under temperature fluctuations or mechanical stress. It also enhances resistance to oils and chemicals, extending the durability of sealing systems used in construction, automotive, and electronics applications.

Cosmetic and Personal Care Industry

• In the cosmetic and personal care field, dimer acid and its esters serve as emollients, film formers, and viscosity regulators. Their mildness and non-irritating nature make them ideal for creams, lotions, and makeup formulations. Dimer acid esters impart a silky touch and improve the spreadability of products while stabilizing emulsions.
• In hair care formulations, dimer acid derivatives act as conditioning agents that enhance softness, smoothness, and anti-static performance. They also contribute to film formation on hair fibers, providing protection and gloss. In sunscreens and long-lasting makeup products, dimer acid-based esters enhance water resistance and improve adhesion of active ingredients to the skin.

Polymer and Engineering Materials

• Dimer acid is a key component in the synthesis of nylon-type polyamides and high-performance polymers. It serves as a flexible building block, improving the elasticity, toughness, and chemical resistance of engineering materials. Polymers derived from dimer acid, such as PA-610 and PA-612, demonstrate excellent mechanical strength and moisture resistance, making them suitable for automotive parts, electrical components, and sporting goods.
• In addition, dimer acid can be used as a modifier to improve the processability of thermoplastics and thermosets. Its inclusion in polymer formulations increases flexibility without compromising structural stability, thereby enhancing both the performance and the processing efficiency of the final product.

Emerging Application Fields

• In emerging industries, dimer acid is gaining recognition as a sustainable bio-based raw material. It is increasingly used in the production of biodegradable polymers, green lubricants, and environmentally friendly coatings. Its renewable origin and biodegradability align with global sustainability goals, promoting the replacement of petroleum-based materials.
• Moreover, dimer acid is being explored for use in 3D printing resins, energy storage materials, and flexible packaging films. Its combination of structural flexibility, oxidative stability, and chemical resistance offers new performance advantages in next-generation materials and advanced manufacturing technologies.
