Description

Castor Oil, Hydrogenated, Polymer With Ethylenediamine, 12-Hydroxyoctadecanoic Acid And Sebacic Acid is a high-performance, multi-functional polyamide resin derived from modified castor oil. This specialized 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 product durability and performance.

Application

• Industrial Coatings & Inks: Acts as a versatile binder and flexibilizer in high-performance polyamide-based coatings, printing inks, and overprint varnishes, offering excellent substrate adhesion and resistance to chemicals and abrasion.
• Adhesives & Sealants: Serves as a key reactive component in hot-melt and reactive polyamide adhesives, providing strong bonding strength, thermal stability, and flexibility for applications in packaging, textiles, and construction.
• Surface Treatment & Primers: Used in formulating primers and surface treatment agents to improve the adhesion of subsequent layers on difficult substrates like metals and treated plastics.
• Chemical & Corrosion Protection: Incorporated into protective coatings and linings for metal structures, pipes, and marine applications due to its inherent resistance to water, salts, and various chemicals.
• Plastic & Rubber Modification: Functions as a compatibilizer and impact modifier in polymer blends and composites, enhancing the toughness and processing characteristics of various thermoplastics and elastomers.

Quality Control

Our polyamide resins are manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each production lot undergoes comprehensive analytical testing, including measurements of amine value, viscosity, softening point, and color. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee compliance with your technical requirements.

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); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product performance.
