Q1: What is the primary function of Aradur 2965 in epoxy systems?
A: Aradur 2965 is an epoxy-modified amine curing agent designed to provide enhanced flexibility, improved adhesion to challenging substrates, and reduced sensitivity to moisture during cure—making it particularly suitable for demanding structural adhesive and coating applications.
Q2: How does Aradur 2965 compare to conventional aliphatic amines in terms of pot life and reactivity?
A: Compared to standard aliphatic amines, Aradur 2965 offers extended pot life at ambient temperatures while maintaining reliable reactivity under moderate heat-cure conditions. Its modified structure balances handling time with efficient network development, supporting both manual and automated processing.
Q3: Is Aradur 2965 compatible with standard diglycidyl ether of bisphenol-A (DGEBA) resins?
A: Yes, Aradur 2965 is formulated for compatibility with common DGEBA-type epoxy resins and demonstrates good solubility and homogeneity without requiring aggressive mixing or elevated temperatures.
Q4: What are typical handling considerations for Aradur 2965?
A: As with most amine-based curing agents, Aradur 2965 should be handled using appropriate personal protective equipment (PPE), including chemical-resistant gloves and eye protection. It is recommended to store in tightly sealed containers under dry, cool conditions to maintain stability and performance consistency.
Q5: Can Aradur 2965 be used in low-VOC or high-solids epoxy formulations?
A: Yes—Aradur 2965 is a liquid, solvent-free curing agent with low volatility, supporting formulation strategies aimed at reducing VOC content and achieving high-solids performance in industrial coatings and adhesives.
