Q1: What types of epoxy resins is D.E.H.805 compatible with?
A: D.E.H.805 is specifically formulated for use with waterborne epoxy dispersions and certain hydrophilically modified bisphenol-A or bisphenol-F based epoxy resins. Compatibility should be confirmed experimentally in the final formulation due to variations in resin functionality, particle size, and stabilization chemistry.
Q2: How does D.E.H.805 contribute to film formation and cure performance in ambient-cure coatings?
A: As a waterborne polyamine curing agent, D.E.H.805 enables coalescence-assisted film formation and facilitates crosslinking at ambient temperatures. It supports good pot life in formulated systems while delivering balanced hardness development, chemical resistance, and adhesion—particularly on metal and concrete substrates.
Q3: Can D.E.H.805 be used in food-contact or hygiene-critical coating applications?
A: D.E.H.805 is not pre-qualified for direct food-contact applications. Formulators intending to use it in coatings for food packaging, processing equipment, or healthcare environments must conduct full regulatory evaluation—including extractables testing and compliance verification against applicable regional requirements—prior to commercial deployment.
Q4: What are key handling and storage recommendations for D.E.H.805?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from freezing and prolonged exposure to high humidity. Avoid contamination with strong acids, isocyanates, or aldehydes. Use appropriate personal protective equipment (PPE) during handling, as with any amine-containing material.
