Huntsman Phenalkamine Curing Agent Aradur 3467xw70 – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Aradur 3467xw70 in epoxy systems?

A: Aradur 3467xw70 is a phenalkamine-based curing agent designed to provide rapid ambient-cure performance for epoxy resins, especially in demanding industrial maintenance and protective coating applications where low-temperature reactivity and moisture tolerance are critical.

Q2: Is Aradur 3467xw70 suitable for use in high-humidity or damp-surface conditions?

A: Yes — as a phenalkamine derivative, it exhibits strong moisture insensitivity and can effectively cure epoxy resins on slightly damp or humid substrates, making it well-suited for field-applied maintenance coatings in challenging environmental conditions.

Q3: How does Aradur 3467xw70 compare to traditional polyamide or aliphatic amine curing agents?

A: Unlike standard polyamides, Aradur 3467xw70 offers significantly faster ambient cure development and improved chemical resistance. Compared to conventional aliphatic amines, it provides lower volatility, reduced odor, and enhanced compatibility with pigments and fillers — while maintaining good flexibility and adhesion.

Q4: Can Aradur 3467xw70 be used in food-contact or potable water applications?

A: Aradur 3467xw70 is not pre-qualified for direct food-contact or potable water applications. Its suitability for such uses depends entirely on full system formulation, post-cure validation, and compliance with relevant regional regulatory requirements — users must conduct appropriate testing and obtain necessary approvals before deployment.
