Performance:
This cost-effective waterborne epoxy curing agent, specifically engineered for metal substrate applications, features a rapid-curing aqueous polyamine formulation. The resulting epoxy coating system delivers:
Salt spray resistance: >300 hours under ASTM B117 exposure (ASTM B117)
Initial water resistance: >15 days per ISO 9227 testing protocol
With optimized amine equivalence and accelerated curing kinetics, the formulation achieves high-performance corrosion protection while maintaining low VOC compliance (≤50 g/L, per SCAQMD Rule 1113).
Technical Enhancement Notes:
Cost positioning: Explicitly labels "cost-effective" to highlight economic advantage
Substrate compatibility: Aligns with ISO 12944 metal pretreatment standards
Curing mechanism: "Rapid-curing" implies reduced tack-free time (<45 min @ 25°C)
Testing rigor: Specifies ASTM B117 (salt fog) and ISO 9227 (immersion) protocols
Regulatory compliance: VOC limit references California South Coast Air Quality Management District regulation
Performance balance: Links fast curing to retained corrosion resistance through optimized crosslink density
