Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Bisphenol A And Diethylenetriamine is a high-performance polymeric resin derived from unsaturated C18 fatty acid dimers, bisphenol A, and diethylenetriamine. This specialized polyamide-type polymer is engineered to deliver exceptional adhesion, flexibility, and chemical resistance, making it a critical component in demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, and ink industries seeking to enhance the performance and durability of their products.

Application

• Industrial & Protective Coatings: Acts as a versatile binder and modifier in epoxy and polyamide curing agents for high-performance marine, maintenance, and industrial coatings, improving adhesion to difficult substrates and corrosion resistance.
• Adhesives & Sealants: Serves as a key resin in reactive hot-melt adhesives and structural sealants, providing excellent initial tack, flexibility, and bond strength to metals, plastics, and composites.
• Printing Inks: Used as a resinous component in specialty printing inks, particularly for overprint varnishes and packaging inks, to enhance gloss, rub resistance, and substrate adhesion.
• Composite Materials: Functions as a toughening agent and compatibility modifier in fiber-reinforced polymer (FRP) composites and matrix resins.
• Foundry & Casting: Employed as a core binder or sand additive in foundry applications to improve mold strength and casting quality.

Quality Control

Our production of Fatty Acids, C18-Unsatd., Dimers, Polymers With Bisphenol A And Diethylenetriamine adheres to stringent quality management protocols. Each batch undergoes rigorous testing for critical parameters including amine value, viscosity, color, and softening point to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flames. Under these conditions, the product is stable for extended periods. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption and skin formation.
