High-purity crystalline platelet morphology ensures excellent flowability and uniform dispersion in solid resin systems.
Exceptional hydrolytic stability due to the sterically hindered neopentyl structure, minimizing ester degradation during processing and service life.
Low volatility and high melting point (≥128 °C) support thermal stability in high-temperature curing applications.
Reactive diol functionality enables robust crosslinking in polyester, alkyd, and polyurethane resins.
Consistent batch-to-batch quality certified under Eastman’s ISO 9001–compliant manufacturing system.
Powder coating resins for architectural and appliance finishes requiring weather resistance and gloss retention.
High-performance alkyd enamels used in industrial maintenance and marine coatings.
Crosslinkers in thermosetting polyester molding compounds (SMC/BMC) for automotive and electrical components.
Monomer building block in specialty polyurethane dispersions (PUDs) for eco-friendly leather and textile coatings.
Stabilizing diol in UV-curable acrylate formulations demanding low shrinkage and high hardness.
