Q1: What is the primary function of Aradur 115 in epoxy systems?
A: Aradur 115 is a polyamide-based curing agent designed to react with epoxy resins, enabling crosslinking at ambient or slightly elevated temperatures. It imparts flexibility, good adhesion, and chemical resistance to the cured network, making it suitable for coatings, adhesives, and repair mortars.
Q2: Is Aradur 115 compatible with standard bisphenol-A and bisphenol-F epoxy resins?
A: Yes, Aradur 115 is broadly compatible with common liquid and solid bisphenol-A and bisphenol-F epoxy resins. Compatibility and cure performance should be verified experimentally within the specific formulation, as resin molecular weight, functionality, and additives can influence reactivity and final properties.
Q3: How does humidity affect the curing process when using Aradur 115?
A: As a polyamide curing agent, Aradur 115 exhibits relatively low sensitivity to ambient moisture compared to amine-based alternatives. However, prolonged exposure to high humidity during cure may lead to surface tackiness or reduced gloss in thin-film applications—proper ventilation and controlled application conditions are recommended.
Q4: Can Aradur 115 be used in food-contact or potable water applications?
A: Aradur 115 is not pre-qualified for direct food-contact or potable water applications under major regulatory frameworks. Formulators must conduct full system-level testing and obtain appropriate regulatory approvals based on the final cured product’s intended use and exposure conditions.
