Description

C18-Unsaturated, Dimers, Hydrogenated, Polymers With Ethylenediamine And Sebacic Acid is a high-performance polyamide resin derived from dimerized fatty acids. This specialized polymer is valued for its excellent flexibility, adhesion, and chemical resistance, making it a critical component in demanding industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Flexible Coatings and Inks: Used as a binder to impart superior flexibility, adhesion, and gloss retention in high-performance industrial and protective coatings, as well as printing inks.
• Hot-Melt and Reactive Adhesives: Serves as a key resin providing excellent tack, cohesive strength, and thermal stability in adhesive formulations for packaging, textiles, and automotive assembly.
• Plastic Modification and Compatibilization: Acts as a polymeric plasticizer and impact modifier to improve the toughness and low-temperature flexibility of engineering plastics and elastomers.
• Corrosion-Resistant Primers: Formulated into primers and anti-corrosion coatings for metal substrates, offering excellent barrier properties and substrate wetting.
• Sealants and Caulks: Provides durable, flexible, and water-resistant properties in construction and automotive sealant applications.
• Powder Coatings: Utilized in carboxyl-functional polyester resins for powder coatings to enhance flow, leveling, and mechanical properties of the final film.

Quality Control

Our C18-Unsaturated, Dimers, Hydrogenated, Polymers With Ethylenediamine And Sebacic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as amine value, acid value, viscosity, and softening point. 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 (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
