Description

C18-Fatty Acids Dimers Polymers With Adipic Acid And Neopentyl Glycol is a high-performance synthetic polyester polyol derived from dimerized fatty acids. This specialized polymer is engineered to provide exceptional flexibility, hydrolytic stability, and compatibility in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Polyurethane Coatings: Serves as a key polyol component for flexible, chemical-resistant, and weatherable coatings for industrial, automotive, and marine applications.
• Adhesives and Sealants: Imparts excellent adhesion, flexibility, and low-temperature performance to polyurethane-based adhesives and sealants.
• Elastomers: Used in the synthesis of castable and thermoplastic polyurethane elastomers requiring a balance of toughness and elasticity.
• Resin Modification: Acts as a flexibilizer and impact modifier for epoxy, polyester, and alkyd resin systems.
• Industrial Lubricants and Greases: Functions as a thickening agent and provides structural stability in complex lubricant formulations.

Quality Control

Our production of C18-Fatty Acids Dimers Polymers With Adipic Acid And Neopentyl Glycol adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, viscosity, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available for every shipment 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); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product properties.
