Description

Fatty Acids, C18-Unsatd., Dimers, Hydrogenated, Polymers With 1,4-Cyclohexanedimethanol, Neopentyl Glycol And Trimethylolpropane is a high-performance, synthetic polyester polyol derived from dimerized fatty acids. This specialized polymer is engineered to deliver exceptional hydrolytic stability, flexibility, and chemical resistance in demanding formulations. It is a critical raw material for manufacturers seeking to enhance the durability and performance of their end products across the coatings, adhesives, and specialty plastics industries.

Application

• High-Performance Polyurethane Coatings: Serves as a key polyol component in two-component (2K) PU coatings for industrial, marine, and automotive applications, providing excellent flexibility and corrosion resistance.
• Adhesives and Sealants: Used in the formulation of flexible, moisture-curing polyurethane adhesives and sealants with strong adhesion to various substrates and good weatherability.
• Elastomers and Casting Resins: Imparts toughness and resilience to polyurethane elastomers used in gaskets, rollers, and industrial parts requiring durability.
• Powder Coatings: Acts as a building block for carboxyl-functional polyester resins used in hybrid and polyurethane powder coating systems, contributing to flow and mechanical properties.
• Specialty Plasticizers and Modifiers: Functions as a polymeric plasticizer or modifier for other resin systems to improve flexibility and impact resistance without migration.
• Inks and Overprint Varnishes: Utilized in specialty ink vehicles and overprint varnishes to enhance film flexibility and substrate adhesion.

Quality Control

Our production of this polyester polyol adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each 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, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for at least 24 months from the date of manufacture. Protect from moisture to prevent potential viscosity changes or gelation.
