Low-VOC, water-based formulation compliant with stringent environmental regulations including EU REACH and China VOC Control Standards.
Excellent compatibility with standard waterborne epoxy resins, enabling stable emulsion formation and extended pot life (≥4 hours at 25°C).
Delivers rapid ambient-cure performance with full hardness development within 24–48 hours under typical workshop conditions (23°C/50% RH).
Provides superior adhesion to concrete, steel, and aged coatings—ideal for repair and refurbishment applications.
Non-yellowing amine adduct chemistry ensures long-term color stability in light-colored and decorative topcoats.
Waterborne epoxy flooring systems for industrial plants, warehouses, and cleanrooms.
Concrete protective coatings in infrastructure projects including bridges, tunnels, and parking decks.
Marine and offshore maintenance coatings requiring low-odor, high-humidity cure capability.
Architectural interior coatings for hospitals, schools, and commercial buildings where indoor air quality is critical.
Repair mortars and grouts for structural rehabilitation of aging concrete substrates.

Q1: What types of waterborne epoxy resins is 3EC154W compatible with?
A: 3EC154W is specifically formulated for use with standard anionic or non-ionic waterborne epoxy dispersions, including bisphenol-A and bisphenol-F based systems. Compatibility should be verified experimentally in the final formulation due to variations in resin particle size, charge stabilization, and surfactant content.
Q2: How does 3EC154W affect pot life and film formation in waterborne epoxy coatings?
A: As a low-VOC, amine-functional curing agent, 3EC154W provides extended working time at ambient temperatures compared to highly reactive aliphatic amines, while still enabling good coalescence and crosslink development during ambient or mild thermal cure. Film hardness and chemical resistance build progressively over several days under typical drying conditions.
Q3: Can 3EC154W be used in food-contact or hygiene-critical coating applications?
A: 3EC154W is designed for industrial and protective coating applications. While it contains no intentionally added heavy metals or formaldehyde, its suitability for direct food-contact or regulated hygiene environments requires full formulation evaluation and compliance verification by the end-user against applicable regional regulatory frameworks.
