Q1: What is the primary chemical nature of D.E.H.115?
A: D.E.H.115 is an aliphatic polyamine-based curing agent, designed to provide rapid ambient-cure reactivity with standard liquid epoxy resins while delivering good flexibility and chemical resistance in the cured network.
Q2: Is D.E.H.115 suitable for food-contact or potable water applications?
A: D.E.H.115 is not pre-qualified for direct food-contact or potable water use. Formulators must conduct full regulatory evaluation—including extractables testing and compliance verification—based on the final cured system and intended application, as performance depends heavily on resin selection, cure conditions, and post-cure treatment.
Q3: How does humidity affect the curing performance of D.E.H.115?
A: As an amine-based hardener, D.E.H.115 is sensitive to atmospheric moisture, which may lead to surface blush or reduced gloss under high-humidity conditions. Optimal results are achieved when applied in controlled environments with moderate relative humidity (typically below 75%) and adequate ventilation.
Q4: Can D.E.H.115 be used with solid or high-molecular-weight epoxy resins?
A: D.E.H.115 is primarily formulated for compatibility with low-viscosity liquid bisphenol-A and bisphenol-F epoxy resins. Its use with solid or highly viscous resins may require elevated mixing temperatures or solvent dilution to ensure homogeneity and complete reaction—pre-formulation testing is strongly recommended.
