Product Introduction
Epoxy Reactive Diluent 669
1. Product Overview
Epoxy Reactive Diluent 669 (Ethylene Glycol Diglycidyl Ether; CAS 2224-15-9) is a high-purity bifunctional epoxy diluent designed for solvent-free epoxy systems. Unlike monofunctional diluents that weaken cured performance, this bifunctional product effectively reduces epoxy resin viscosity while maintaining high cross-linking density, excellent mechanical strength, and chemical resistance. It reacts completely with epoxy resins and curing agents during curing, integrating into the final coating or adhesive structure without volatile residue, making it a core auxiliary for high-performance epoxy applications.

3. Key Features & Applications
Core Features: Low viscosity, excellent dilution capacity, stable reaction activity, low shrinkage, outstanding toughness and heat resistance. It avoids performance degradation caused by molecular chain termination, improving the flexibility and elongation at break of cured epoxy products. It also features low volatility and high compatibility with all standard epoxy resins and amine curing systems.
Main Applications: Widely used in epoxy floor coatings, anti-corrosion coatings, electronic potting materials, casting compounds, structural adhesives, and composite materials. Additionally, it serves as a textile finishing agent, silk anti-wrinkle agent, and thermal stabilizer for PVC and high-chloride compounds.
4. Packaging, Storage & Shipping
Packaging: Standard 200kg iron/plastic drums, or customized packaging as required.
Storage: Store in a cool, dry, ventilated warehouse, away from fire, heat sources, and strong oxidants. Seal tightly to avoid moisture absorption and invalidation. Shelf life: 12 months under normal temperature.
Sea Shipping Information: Non-dangerous goods for international transportation. No UN number required. It is not classified as flammable, toxic, or corrosive dangerous goods, supporting safe and convenient global sea freight delivery.
