Q1: What is the primary function of Aradur 2958 in epoxy systems?
A: Aradur 2958 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 2958 suitable for use in coatings requiring low VOC and low odor?
A: Yes — as a non-volatile, low-odor modified amine, Aradur 2958 supports formulations targeting reduced VOC emissions and improved workplace handling, particularly in industrial maintenance and protective coating applications.
Q3: How does Aradur 2958 compare to standard DETA or TETA in terms of reactivity and handling safety?
A: Aradur 2958 offers moderated reactivity versus highly reactive polyamines like DETA or TETA, resulting in extended pot life and reduced skin sensitization potential. It maintains effective cure performance while improving formulation safety and process control.
Q4: Can Aradur 2958 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 storage conditions are recommended to maintain optimal performance?
A: Store in original sealed containers at temperatures between 10°C and 30°C, protected from moisture and direct sunlight. Prolonged exposure to humidity or freezing may affect viscosity and reactivity.
