Description

Hexanedioic Acid, Polymer With 1,3-Butanediol, 1,3-Isobenzofurandione And 1,2-Propanediol, Octadecanoate CAS NO 68238-78-8 is a specialized polyester-based polymer designed to deliver enhanced performance characteristics in demanding formulations. This engineered copolymer is valued for its ability to modify rheology, improve flexibility, and provide excellent compatibility within complex systems. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced polymer modification and specialty plasticizer applications.

Application

• High-Performance Industrial Coatings: Acts as a rheology modifier and flexibilizer in solvent-borne and high-solids coatings, improving film formation and durability.
• Adhesives and Sealants: Used to enhance tack, adhesion, and low-temperature flexibility in polyurethane and other polymer-based adhesive systems.
• Polymer Modification: Serves as an impact modifier or compatibilizer in engineering plastics and thermoplastic elastomers (TPEs) to tailor mechanical properties.
• Specialty Plasticizers: Functions as a secondary plasticizer or stabilizer in PVC and other polymer compounds, contributing to improved processing and longevity.
• Ink Formulations: Utilized in specialty printing inks to adjust viscosity, gloss, and substrate adhesion.
• Resin Intermediates: Employed in the synthesis of more complex polyester or alkyd resins for tailored performance profiles.
