Q1: What is the primary function of Aradur 2992 in epoxy systems?
A: Aradur 2992 is a modified amine curing agent designed to provide efficient room-temperature or elevated-temperature cure of epoxy resins, delivering good chemical resistance, mechanical strength, and reduced amine blush compared to conventional aliphatic amines.
Q2: Is Aradur 2992 suitable for coatings requiring low VOC and low odor?
A: Yes — as a non-volatile, low-odor modified amine, Aradur 2992 supports formulations targeting reduced VOC content and improved workplace handling, particularly in industrial maintenance and protective coating applications.
Q3: How does Aradur 2992 compare to standard DETA or TETA in terms of reactivity and handling?
A: Aradur 2992 offers moderated reactivity relative to highly reactive polyamines like DETA or TETA, resulting in extended pot life and improved formulation stability, while still enabling robust cure performance across a range of ambient and heated conditions.
Q4: Can Aradur 2992 be used in high-solids or solvent-free epoxy systems?
A: Yes — its low volatility and compatibility with common epoxy resins make it well-suited for high-solids, low-VOC, and 100% solids epoxy formulations, including flooring, grouts, and structural adhesives.
Q5: What are typical storage and handling recommendations for Aradur 2992?
A: Store in original sealed containers at temperatures between 10–30°C, protected from moisture and direct sunlight. Use appropriate personal protective equipment (PPE) during handling, as with all amine-based curing agents, and avoid prolonged skin contact.
