Enhanced reactivity with epoxy resins at ambient and low temperatures (down to 5°C).
Improved flexibility and impact resistance in cured epoxy systems without sacrificing thermal stability.
Low viscosity (< 800 mPa·s at 25°C) enabling easy metering, mixing, and improved filler wetting.
Reduced volatility and amine odor compared to conventional aromatic amines, supporting safer handling.
Excellent chemical resistance — particularly to alkalis, solvents, and mild acids in protective coatings.
High-performance epoxy flooring systems for industrial and commercial facilities.
Structural adhesives requiring fast development of handling strength at ambient conditions.
Anti-corrosive primers and topcoats for steel infrastructure and marine environments.
Electrical encapsulation and potting compounds demanding low exotherm and dimensional stability.
Repair mortars and grouts where rapid cure and early load-bearing capacity are critical.
