Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Diethylenetriamine And Tall-Oil Fatty Acids is a high-performance polyamide resin intermediate derived from dimerized and polymerized unsaturated C18 fatty acids, primarily from tall oil, and reacted with diethylenetriamine. This compound is valued for its ability to impart excellent adhesion, flexibility, and water resistance in formulated products. It is a critical raw material for manufacturers in the coatings, adhesives, and ink industries seeking to enhance the durability and performance of their end products.

Application

• Corrosion-Resistant Coatings: Used as a curing agent and flexibilizer in epoxy-based primers and topcoats for industrial and marine applications.
• High-Performance Adhesives: Serves as a key component in polyamide hot-melt and reactive adhesives, providing strong bonding on diverse substrates.
• Printing Inks: Acts as a resin modifier in solvent-based and overprint varnishes to improve gloss, adhesion, and rub resistance.
• Construction Chemicals: Incorporated into sealants and concrete curing compounds to enhance waterproofing and durability.
• Industrial Maintenance Paints: Formulated into heavy-duty protective coatings for steel structures, pipelines, and storage tanks.
• Can and Coil Coatings: Utilized to improve the formability and corrosion protection of metal coatings.

Quality Control

Our production of this polyamide resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as amine value, viscosity, and color are rigorously tested. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance processes.

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 easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) in the headspace of partially used containers is recommended to preserve product integrity. Keep away from strong oxidizers.
