Q1: What types of epoxy resins is Kukdo Chemical 300 compatible with?
A: Kukdo Chemical 300 is designed for use with standard liquid and solid bisphenol-A and bisphenol-F based epoxy resins, as well as many novolac and cycloaliphatic epoxies. Compatibility should be confirmed through small-scale formulation trials due to variations in resin functionality and molecular weight.
Q2: How does Kukdo Chemical 300 affect pot life and cure speed compared to conventional polyamide curing agents?
A: Kukdo Chemical 300 offers an extended working time at ambient temperatures while maintaining efficient cure development upon heating. It generally provides longer pot life than fast-reactive amines but faster ambient or elevated-temperature cure onset than traditional low-reactivity polyamides.
Q3: Is Kukdo Chemical 300 suitable for high-performance coating applications requiring chemical resistance?
A: Yes — when fully cured in epoxy systems, Kukdo Chemical 300 contributes to excellent resistance to alkalis, solvents, and moderate acid exposure. Performance depends on proper stoichiometry, complete cure cycle, and overall formulation design, including pigment and filler selection.
Q4: Can Kukdo Chemical 300 be used in low-VOC or solvent-free epoxy formulations?
A: Yes — Kukdo Chemical 300 is a low-viscosity, non-solvented liquid that supports high-solids and 100% solids epoxy systems. Its reactivity profile allows for reduced need for reactive diluents in many applications, supporting VOC-compliant formulation strategies.
