Q1: What is the primary application of Aradur 115X70?
A: Aradur 115X70 is a polyamide-based curing agent designed for use with epoxy resins in high-performance industrial coatings, adhesives, and composite systems—particularly where flexibility, chemical resistance, and good adhesion to damp or marginally prepared substrates are required.
Q2: How does Aradur 115X70 differ from conventional aliphatic polyamide curing agents?
A: Aradur 115X70 is formulated to offer improved compatibility with a broader range of epoxy resins, enhanced pot life at ambient temperatures, and more consistent film formation—especially in formulations requiring reduced viscosity without sacrificing final cure performance.
Q3: What are typical mixing and curing conditions for this product?
A: It is generally mixed with liquid or solid epoxy resins at ambient temperature using standard mechanical agitation. Full cure typically develops over 24–72 hours at room temperature, with accelerated cure achievable at elevated temperatures (e.g., 60–80 °C), depending on formulation design and substrate requirements.
Q4: Is Aradur 115X70 suitable for food-contact or potable water applications?
A: Aradur 115X70 is not pre-qualified for direct food-contact or potable water applications. Formulators must conduct full regulatory evaluation—including migration testing and compliance verification—based on final cured system composition, end-use conditions, and applicable regional regulations.
