ARADUR 22 is a reactive amine curing agent specifically formulated for use with liquid epoxy resin systems in construction and industrial applications.
ARADUR 22 contains active hydrogen groups that react chemically with epoxy functionalities, initiating a polyaddition reaction that forms a durable, three-dimensional thermoset polymer network.

This curing process occurs efficiently at ambient or slightly elevated temperatures, making ARADUR 22 suitable for field-applied systems where heat curing is not practical.
The cured epoxy systems produced with ARADUR 22 typically exhibit strong adhesion to concrete, steel, and mineral substrates, along with good mechanical strength, abrasion resistance, and chemical durability.

ARADUR 22's balanced reactivity allows sufficient working time for application while ensuring reliable crosslink development and surface hardness.
ARADUR 22 is commonly used in solvent-free coatings, industrial floor systems, epoxy mortars, grouting compounds, and structural repair materials where long-term performance and resistance to mechanical and environmental stress are required.
