Description

Poly(Dimer Acid-Co-Alkyl Polyamine) is a high-performance polymeric resin synthesized from dimerized fatty acids and alkyl polyamines. This versatile polyamide-type polymer is valued for its excellent adhesive properties, flexibility, and chemical resistance, making it a critical component in demanding industrial formulations. It is primarily sought after by manufacturers in the adhesives, coatings, and ink industries seeking to enhance product durability and performance.

Application

• Hot-Melt Adhesives (HMA): Acts as a key tackifier and flexibilizer, providing strong bonding on various substrates including plastics, metals, and textiles.
• Inks and Overprint Varnishes: Used as a resin to improve gloss, adhesion, and rub resistance in flexographic and gravure printing inks.
• Industrial Coatings: Imparts flexibility and corrosion resistance in protective coatings for wires, cables, and metal parts.
• Composite Materials: Serves as a compatibilizer and binder in fiber-reinforced plastics and other composite systems.
• Sealants and Caulks: Provides permanent flexibility and adhesion in construction and automotive sealant applications.
• Can and Container Coatings: Employed in formulations requiring excellent adhesion to metal surfaces and resistance to contents.

Quality Control

Our Poly(Dimer Acid-Co-Alkyl Polyamine) is manufactured under a strict quality management system. Each batch is tested against key parameters including amine value, acid value, softening point, and viscosity to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) documenting these specifications are available upon request.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
