Low Voc Water Based Epoxy Curing Agent For Metal Substrate Applications

It is a water-soluble modified polyamine adduct, recommended to be used with water-based epoxy resin, designed for anti-corrosion primers for various metal substrates and epoxy floor paints.

Physical Property:

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
