Q1: What are the key performance advantages of EPIKURE 3370 compared to conventional aliphatic amine curing agents?
A: EPIKURE 3370 offers enhanced UV stability, lower volatility, and reduced skin sensitization potential due to its cycloaliphatic amine structure. It provides improved yellowing resistance and better long-term gloss retention in clear coatings and outdoor applications, while maintaining good reactivity at ambient to moderate elevated temperatures.
Q2: Is EPIKURE 3370 suitable for use in high-performance protective coatings exposed to harsh environments?
A: Yes — it is commonly selected for demanding protective coating systems, including industrial maintenance, marine, and infrastructure applications. Its cured epoxy networks demonstrate excellent chemical resistance, adhesion to properly prepared substrates, and durability under thermal cycling and humid conditions.
Q3: How does EPIKURE 3370 behave in terms of pot life and cure speed relative to other cycloaliphatic amines?
A: EPIKURE 3370 delivers a balanced profile: it offers a practical pot life suitable for typical application methods (e.g., brushing, rolling, or spraying), with noticeable film build and handling strength development within several hours at room temperature. Full property development typically benefits from mild thermal post-cure, though ambient cure is viable for many formulations.
Q4: Can EPIKURE 3370 be used in low-VOC or solvent-free epoxy systems?
A: Yes — it is compatible with low-viscosity liquid epoxies and reactive diluents, enabling formulators to design high-solids or 100% solids epoxy systems. Its low vapor pressure supports compliance with VOC reduction initiatives without compromising handling safety or cure efficiency.
