Q1: What is the primary function of ARADUR 36 BD in epoxy coating systems?
A: ARADUR 36 BD is a low-viscosity, amine-based curing agent designed to react with epoxy resins—particularly bisphenol A and bisphenol F types—to form durable, chemically resistant thermoset coatings. It enables rapid development of hardness and early handling strength while supporting excellent adhesion to metallic and concrete substrates.
Q2: Is ARADUR 36 BD suitable for high-solids or solvent-free epoxy coating formulations?
A: Yes—its low viscosity and high reactivity make it well-suited for high-solids and solvent-free epoxy coating systems. It contributes to low VOC content and supports formulation flexibility without requiring excessive diluents or reactive thinners.
Q3: How does ARADUR 36 BD compare to conventional polyamide or aliphatic amine curing agents in terms of pot life and cure speed?
A: ARADUR 36 BD offers a balanced profile: longer pot life than highly reactive aliphatic amines, yet faster ambient-temperature cure than standard polyamides. This makes it especially useful for industrial maintenance and protective coating applications where working time and early serviceability must be optimized.
Q4: Can ARADUR 36 BD be used in food-contact or potable water coating systems?
A: ARADUR 36 BD is not pre-approved for direct food-contact or potable water applications. Formulators intending such use must conduct full regulatory evaluation—including migration testing and compliance verification per applicable local and regional requirements—prior to commercial deployment.
Q5: What are key storage and handling considerations for ARADUR 36 BD?
A: Store in original sealed containers under dry, cool conditions (typically below 30 °C) and protect from moisture and prolonged exposure to air, as it is hygroscopic and may absorb CO₂ over time. Use appropriate personal protective equipment (PPE), including chemical-resistant gloves and eye protection, during handling due to its amine functionality.
