Q1: What is the primary application of Aradur 422XW 70?
A: Aradur 422XW 70 is a low-viscosity, water-white polyamide curing agent designed primarily for use in high-performance epoxy coating systems—especially those requiring excellent chemical resistance, flexibility, and adhesion on damp or marginally prepared substrates.
Q2: Is Aradur 422XW 70 compatible with standard liquid epoxy resins?
A: Yes, it is broadly compatible with common bisphenol-A and bisphenol-F based liquid epoxy resins. Its low viscosity and water-white appearance support formulation of clear, aesthetically demanding coatings and self-leveling systems without compromising pot life or cure profile.
Q3: How does Aradur 422XW 70 perform under humid or low-temperature conditions?
A: It demonstrates enhanced moisture tolerance compared to conventional polyamide hardeners, enabling more reliable curing in ambient conditions with elevated humidity or moderate temperature reductions—making it suitable for field-applied protective coatings where climate control is limited.
Q4: What safety and handling considerations apply to this product?
A: As with all amine-based curing agents, appropriate personal protective equipment—including gloves, eye protection, and adequate ventilation—is recommended during handling. The product is non-irritating to skin in its fully formulated state but may cause sensitization with repeated or prolonged exposure in uncured form.
