Product application
HF-8618 epoxy curing agent is a low color, low viscosity modified cycloaliphatic amine intended for ambient or low temperature curing of liquid epoxy resins. HF-8618 gives high gloss films that are resistant to a variety of chemicals.
• These properties make it ideal for formulating floorings, maintenance coatings, tank linings, and secondary containment linings. It’s very low color and good color stability make it appropriate for clear and pastel shade coating.
• Very low color and good color stability
• Good chemical resistance (see attached)
• High gloss
• Good resistance to amine blush
• Low viscosity
