Waterborne Epoxy Curing Agent - Fast Curing for Durable Coatings
Product Overview
Waterborne Epoxy Curing Agent ECA-200F is a next-generation, amine-functionalized aqueous dispersion engineered to revolutionize the performance and sustainability of epoxy coating systems. Designed for fast curing at ambient temperatures (5–40°C), this curing agent enables full crosslinking of epoxy resins within 2–4 hours while delivering unmatched chemical resistance, adhesion, and mechanical durability. Compatible with a wide range of waterborne epoxy emulsions, ECA-200F is ideal for industrial maintenance, marine coatings, and food-grade floor systems requiring rapid return-to-service and compliance with global VOC regulations (<50 g/L, EPA Method 24).
Core Innovations
1. Advanced Curing Mechanism
- Reactive amine technology:
- Primary/secondary amine blend accelerates cure without exothermic risks.
- Achieves 80% crosslink density in 90min @25°C (DSC analysis).
- Self-emulsifying system:
- Stabilizes epoxy resin droplets via electrostatic repulsion (zeta potential >-40mV).
2. Dual-Function Performance
- Rapid curing:
- Walk-on time: 2h (ASTM D1640-03).
- Full cure: 24h (vs. 7d for conventional waterborne epoxies).
- Long pot life:
- 60–90min working time (ISO 9514).
