Description

Fettsuren, C18-Ungesttigt, Trimerisiert, Methylester is a specialized trimerized fatty acid methyl ester derived from unsaturated C18 fatty acids. This high-performance chemical intermediate is valued for its enhanced thermal stability, low volatility, and excellent compatibility with polymers and resins. It serves as a critical building block for manufacturers in the coatings, adhesives, and lubricant industries seeking to improve product durability and performance. Its unique structure provides superior properties compared to monomeric or dimeric derivatives.

Application

• Polymer & Resin Modification: Acts as a reactive diluent, plasticizer, or cross-linking agent in alkyd, epoxy, and polyester resins to enhance flexibility and reduce viscosity.
• High-Performance Lubricants & Greases: Used as a synthetic base stock or additive to improve thermal-oxidative stability, lubricity, and load-bearing capacity.
• Adhesives & Sealants: Imparts improved adhesion, cohesion, and low-temperature flexibility in hot-melt, pressure-sensitive, and structural adhesive formulations.
• Surface Coatings & Inks: Functions as a film-forming agent and modifier in industrial and protective coatings, improving gloss, flow, and chemical resistance.
• Fuel & Lubricant Additives: Employed as a detergent or dispersant component to control deposits and improve cleanliness in engine oils and fuels.
• Chemical Intermediate: Serves as a precursor for further synthesis of polyamides, polyesters, and other specialty chemicals.

Quality Control

Our Fettsuren, C18-Ungesttigt, Trimerisiert, Methylester is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. Key parameters such as acid value, saponification value, viscosity, and color are strictly monitored. Certificates of Analysis (COA) documenting purity and physical properties are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong alkalis and organic solvents. Recommended storage temperature is between 15°C and 25°C. Keep containers tightly sealed when not in use to minimize moisture absorption and contamination.
