Q1: What is the primary application of Aradur 3460?
A: Aradur 3460 is a phenalkamine-based curing agent designed for use with epoxy resins in high-performance protective coatings—particularly where rapid ambient-cure performance, excellent adhesion to damp or marginally prepared substrates, and strong chemical resistance are required.
Q2: How does Aradur 3460 differ from conventional amine curing agents?
A: Unlike standard aliphatic amines, Aradur 3460 combines phenolic and alkylamine functionality, offering improved hydrophobicity, reduced sensitivity to CO₂-induced blushing, and enhanced compatibility with epoxy systems at lower mixing viscosities—enabling better formulation flexibility and application efficiency.
Q3: Is Aradur 3460 suitable for low-VOC or solvent-free formulations?
A: Yes—Aradur 3460 is a low-viscosity, reactive liquid with negligible volatility, making it well-suited for low-VOC, high-solids, and 100% solids epoxy systems without requiring volatile solvents for viscosity adjustment.
Q4: What kind of epoxy resins is Aradur 3460 typically compatible with?
A: Aradur 3460 demonstrates broad compatibility with standard liquid and solid bisphenol-A and bisphenol-F epoxy resins, as well as modified epoxies such as novolac and cycloaliphatic types—though optimal performance is achieved when matched with medium-to-high molecular weight liquid epoxies.
Q5: How should Aradur 3460 be stored and handled?
A: Store in tightly sealed containers under dry, cool conditions (below 30°C) and protected from moisture. Due to its amine functionality, avoid prolonged exposure to air and humidity during handling to prevent potential surface film formation or reactivity loss over time.
