Description

Fatty Acids, C18-Unsatd., Dimers, Hydrogenated, Reaction Products With C>14 Alcs. And Hexamethylenediamine CAS NO 172776-94-2 is a high-performance, synthetic polyamide intermediate derived from hydrogenated dimer acids and long-chain alcohols. This specialized chemical is engineered to provide exceptional thermal stability, flexibility, and adhesion properties in demanding polymer formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Hot-Melt Adhesives (HMA): Acts as a key tackifier and flexibilizer, improving low-temperature performance and adhesion to non-porous substrates like plastics and metals.
• Industrial & Protective Coatings: Used in polyamide-based resin formulations for corrosion-resistant primers, can coatings, and powder coatings, offering excellent chemical resistance.
• Inks & Overprint Varnishes: Imparts flexibility and scuff resistance to polyamide resins used in packaging and printing inks.
• Plastic Additives: Functions as a compatibilizer and processing aid in engineering plastics and polymer blends.
• Sealants & Caulks: Enhances the elasticity, durability, and adhesion of polyamide-based sealant formulations.
• Fiber Modification: Utilized in the production of synthetic fibers to improve dyeability and moisture management properties.

Quality Control

Our production of this polyamide intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as amine value, softening point, and viscosity are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
