Description

1,3-Benzenedicarboxylic Acid, Polymer With 2-(Hydroxymethyl)-2-Methyl-1,3-Propanediol, Nonanoate is a high-performance polymeric ester, also known as a branched polyester polyol, derived from isophthalic acid and trimethylolpropane. This compound matters for its role as a versatile building block in the synthesis of advanced polymers, offering excellent hydrolytic stability, flexibility, and adhesion properties. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as by manufacturers of specialty polyurethanes and plasticizers.

Application

• Polyurethane Resins: A key raw material for producing flexible and rigid polyurethane foams, coatings, and elastomers.
• High-Performance Coatings: Used in alkyd and polyester resins for industrial, automotive, and marine coatings requiring durability and chemical resistance.
• Adhesives & Sealants: Imparts flexibility and strong adhesion in construction and automotive sealant and adhesive formulations.
• Plasticizers: Acts as a polymeric plasticizer for PVC and other polymers, enhancing flexibility and longevity.
• Synthetic Lubricants: Serves as a base stock or additive in high-performance lubricants and greases.
• Ink Vehicles: Used in the manufacture of resins for printing inks, improving gloss and substrate adhesion.
