Description

Fatty Acids, C16-18 And C18-Unsatd., Polymers With 1,4-Cyclohexanedimethanol, Isophthalic Acid And Trimethylolpropane is a high-performance, synthetic polyester polyol resin designed for demanding industrial applications. This specialized polymer offers a unique balance of flexibility, chemical resistance, and durability derived from its tailored fatty acid and aromatic acid backbone. It is primarily sought by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance. The material, identified by CAS No. 68956-02-5, provides a versatile building block for creating advanced polymeric networks.

Application

• High-Performance Industrial Coatings: Used as a key polyol component in polyurethane and alkyd resin formulations for protective coatings, marine paints, and corrosion-resistant finishes.
• Adhesives and Sealants: Imparts flexibility and adhesion in polyurethane-based adhesives, sealants, and potting compounds.
• Elastomers: Serves as a soft segment or chain extender in the synthesis of thermoplastic polyurethanes (TPU) and other elastomeric materials.
• Resin Modifier: Used to modify the properties of other polyester or acrylic resins, improving impact resistance and weatherability.
• Ink Vehicles: Employed in the formulation of specialty printing inks requiring excellent substrate wetting and film properties.
• Fiber and Textile Treatments: Can be utilized in coatings and finishes for synthetic fibers and technical textiles.
