Q1: What is the primary function of Aradur 3230 CI in epoxy systems?
A: Aradur 3230 CI is an epoxy-modified amine curing agent designed to provide enhanced compatibility, reduced volatility, and improved flexibility in cured epoxy networks—particularly beneficial for coatings, adhesives, and composite matrices requiring balanced reactivity and toughness.
Q2: How does Aradur 3230 CI differ from conventional aliphatic amines?
A: Unlike standard aliphatic amines, Aradur 3230 CI features covalently bound epoxy segments that lower vapor pressure, improve resin compatibility, and moderate cure speed—resulting in reduced blush tendency, better pot life control, and improved intercoat adhesion in multi-layer applications.
Q3: Is Aradur 3230 CI suitable for low-VOC or high-solids formulations?
A: Yes—its low volatility and high active hydrogen equivalent weight make it well-suited for low-VOC, high-solids, and solvent-free epoxy systems, supporting compliance with evolving environmental and occupational health requirements without compromising film formation or mechanical performance.
Q4: What types of epoxy resins is Aradur 3230 CI typically compatible with?
A: It demonstrates broad compatibility with standard liquid and solid bisphenol-A/F epoxy resins, novolac epoxies, and cycloaliphatic epoxies—enabling formulation flexibility across protective coatings, electrical encapsulants, and structural composites.
Q5: How should Aradur 3230 CI be handled and stored to maintain stability?
A: Store in tightly sealed containers under dry, cool conditions (typically below 30 °C) and protect from moisture and prolonged exposure to air; pre-use mixing may be required if phase separation occurs during extended storage, and material should be used within recommended shelf-life guidelines to ensure consistent reactivity.
