Q1: What is the primary function of Aradur 460 J90 in epoxy systems?
A: Aradur 460 J90 is a polyamide-based curing agent designed to react with epoxy resins, enabling crosslinking and development of mechanical strength, chemical resistance, and adhesion—particularly in ambient-cure or low-temperature coating and adhesive formulations.
Q2: Is Aradur 460 J90 suitable for food-contact applications?
A: Aradur 460 J90 is not pre-qualified for direct food-contact use. Formulators must conduct full regulatory evaluation—including migration testing and compliance verification—based on final cured system composition, intended conditions of use, and applicable regional regulations.
Q3: How does Aradur 460 J90 compare to conventional aliphatic polyamide curing agents in terms of pot life and film formation?
A: Aradur 460 J90 offers extended pot life relative to many standard polyamides while maintaining good film-forming characteristics at ambient temperatures. It supports balanced reactivity—enabling sufficient working time without compromising final cure performance or surface quality in protective coatings.
Q4: Can Aradur 460 J90 be used in high-solids or solvent-free epoxy systems?
A: Yes—Aradur 460 J90 is formulated for compatibility with medium-to-high-solids epoxy resins and can be adapted for solvent-free systems. Its viscosity and reactivity profile support formulation flexibility, though final rheology and cure behavior should be verified experimentally for each specific resin blend.
