Description

Fettsuren, C22-Ungesttigt, Dimerisiert is a high-purity, unsaturated C22 dimerized fatty acid. This specialty chemical is valued for its unique molecular structure, offering enhanced thermal stability, flexibility, and reactivity compared to monomeric fatty acids. It serves as a critical building block for manufacturers in the polymer, lubricant, and adhesive industries seeking to improve product performance.

Application

• Polyamide Resins: A key monomer for producing high-performance, flexible polyamide hot-melt adhesives and coatings.
• Polyester Polyols: Used in the synthesis of polyols for elastomers, sealants, and flexible polyurethane foams.
• Corrosion Inhibitors: Acts as an effective intermediate in formulating lubricant additives and metalworking fluid components.
• Epoxy Curing Agents: Serves as a reactive modifier to impart toughness and flexibility to epoxy resin systems.
• Alkyd Resins: Employed to enhance the durability and drying properties of surface coatings and paints.
• Synthetic Lubricants: A precursor for high-temperature stable ester-based lubricants and greases.
