Product Overview
Neopentyl glycol diglycidyl ether (NGDE, CAS 17557-23-2) is a low-viscosity, high-reactivity epoxy monomer. It is a pale yellow transparent liquid with no irritating odor, featuring two epoxy groups in the molecular structure. It exhibits excellent compatibility with bisphenol A epoxy resins, widely serving as an active diluent and cross-linking agent in epoxy systems. Manufactured via advanced synthesis and purification, it delivers high purity, stable batch consistency, and low toxicity for industrial and coating applications.
Product Features
- Low Viscosity: 10–30 mPa.s (25 °C), effectively reducing epoxy resin viscosity for easy formulation and processing.
- High Reactivity: Contains two epoxy groups, enabling efficient cross-linking and curing to form high-strength networks.
- Good Compatibility: Miscible with most epoxy resins, improving processability without compromising cured performance.
- Low Toxicity: Safer handling compared to conventional diluents, suitable for environmental-friendly formulations.
- Stable Properties: Resistant to hydrolysis and thermal degradation under normal storage and usage conditions.
- Excellent Mechanical Strength: Enhances tensile, flexural, compressive, and impact strength of cured epoxy systems.
