High-purity crystalline solid with ≥99.0% assay for consistent reactivity in polymer synthesis.
Two primary hydroxyl groups and one carboxylic acid group enable dual functionality in waterborne polyurethane and polyester resins.
Excellent solubility in common polar solvents (e.g., DMF, THF, acetone) and compatibility with amine- and isocyanate-based systems.
Low volatility and thermal stability up to 180°C support safe handling and processing in industrial curing operations.
Non-toxic, REACH-compliant raw material suitable for coatings and adhesives requiring low-VOC and eco-friendly formulations.
Internal emulsifier and chain extender in waterborne polyurethane dispersions (PUDs) for leather finishes and textile coatings.
Hydrophilic modifier in automotive and industrial water-based topcoats to enhance gloss, adhesion, and film integrity.
Functional monomer in UV-curable acrylic-polyurethane hybrid resins for wood and plastic coatings.
Carboxyl-functional building block in high-performance polyester resins for powder coating applications.
Key ingredient in biodegradable polyurethane foams and elastomers for medical device encapsulation.
