Q1: What is the primary function of Aradur 145 in epoxy systems?
A: Aradur 145 is a polyamide-based curing agent designed to react with epoxy resins, enabling crosslinking at ambient or slightly elevated temperatures. It delivers good flexibility, chemical resistance, and adhesion—particularly suited for protective coatings, flooring, and industrial maintenance applications.
Q2: Is Aradur 145 compatible with standard bisphenol A and bisphenol F epoxy resins?
A: Yes, Aradur 145 is broadly compatible with common liquid and solid bisphenol A- and bisphenol F-type epoxy resins. Compatibility and final film properties depend on resin molecular weight, formulation solids content, and intended cure profile—preliminary lab-scale testing is recommended for new formulations.
Q3: How does humidity affect the cure performance of Aradur 145?
A: As a polyamide curing agent, Aradur 145 exhibits relatively low sensitivity to ambient moisture compared to amine-based alternatives, supporting reliable curing under moderate humidity conditions. However, prolonged exposure to high relative humidity (>85%) during early cure stages may delay surface dryness or impact gloss uniformity.
Q4: Can Aradur 145 be used in food-contact or potable water applications?
A: Aradur 145 is not pre-qualified for direct food-contact or potable water applications under major regulatory frameworks. Its suitability for such uses must be evaluated case-by-case based on full system formulation, end-use conditions, and compliance verification with relevant national or regional authorities.
