Q1: What is the primary function of Aradur 450 in epoxy systems?
A: Aradur 450 is a polyamide-based curing agent designed to react with epoxy resins, enabling crosslinking at ambient or slightly elevated temperatures. It delivers balanced flexibility, chemical resistance, and adhesion—particularly suited for protective coatings, flooring, and industrial maintenance applications.
Q2: Is Aradur 450 suitable for low-VOC or high-solids formulations?
A: Yes—Aradur 450 is a low-viscosity, solvent-free polyamide curing agent, making it well-suited for high-solids and low-VOC epoxy systems. Its formulation supports compliance with evolving environmental regulations without compromising pot life or film performance.
Q3: How does Aradur 450 compare to aliphatic amine curing agents in terms of handling and safety?
A: Unlike highly reactive aliphatic amines, Aradur 450 offers lower volatility, reduced skin sensitization potential, and extended working time—making it safer and more user-friendly in industrial settings. Personal protective equipment (PPE) is still recommended, but handling requirements are generally less stringent.
Q4: Can Aradur 450 be used in food-contact or potable water applications?
A: Aradur 450 is not pre-approved for direct food-contact or potable water applications. Its suitability for such uses depends on full system formulation, final cure conditions, and regulatory evaluation by qualified toxicologists and certifying bodies—end users must conduct appropriate testing and obtain necessary approvals.
