Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Azelaic Acid, Ethylenediamine, Isostearic Acid And Piperazine CAS NO 68604-88-6 is a high-performance, multi-component polymeric resin derived from vegetable-based fatty acids. This specialized chemical is engineered to provide exceptional adhesion, flexibility, and chemical resistance in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and polymer modification industries seeking to enhance product durability and performance.

Application

• Corrosion-Resistant Coatings: Acts as a key polymeric binder in high-performance industrial and marine coatings, providing excellent barrier properties and adhesion to metal substrates.
• Adhesives and Sealants: Used as a tackifying and flexibilizing agent in structural adhesives, pressure-sensitive adhesives (PSAs), and construction sealants.
• Polymer Modification: Employed as a reactive modifier for epoxy, polyester, and alkyd resins to improve impact resistance, flexibility, and weatherability.
• Printing Inks: Serves as a resin component in specialty printing inks, contributing to gloss, rub resistance, and substrate adhesion.
• Foundry Resins: Utilized in core and mold binders for metal casting due to its thermal stability and binding characteristics.
• Personal Care Polymers: Can be formulated into film-forming agents for hair sprays, sunscreens, and other cosmetic products requiring water resistance.

Quality Control

Our production of this polyamide resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as amine value, viscosity, and softening point are rigorously tested. A Certificate of Analysis (COA) detailing specific lot results is provided with every shipment. We support compliance with relevant global standards for industrial chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen blanket) after opening to prevent oxidation and moisture absorption, which can affect viscosity and reactivity. Keep away from heat sources and open flame.
