Q1: What types of epoxy resins is D.E.H.804 compatible with?
A: D.E.H.804 is specifically formulated for use with waterborne epoxy dispersions and certain hydrophilically modified solid or liquid epoxy resins. It demonstrates good compatibility and reactivity with standard bisphenol A-based and bisphenol F-based waterborne epoxy systems.
Q2: How does D.E.H.804 contribute to film formation and cure performance in low-VOC coatings?
A: As a waterborne curing agent, D.E.H.804 enables ambient- or low-temperature coalescence and crosslinking without requiring high-bake conditions. It supports the development of durable, chemically resistant films while maintaining low VOC content and favorable application properties such as extended pot life and good flow/leveling.
Q3: Can D.E.H.804 be used in corrosion-resistant industrial maintenance coatings?
A: Yes — D.E.H.804 is commonly selected for waterborne industrial maintenance and protective coatings where balanced hardness, flexibility, and resistance to moisture, salts, and mild chemicals are required. Its performance is optimized when formulated into two-component systems designed for steel substrates and moderate-service environments.
Q4: What are the key handling and storage recommendations for D.E.H.804?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from freezing and direct sunlight. Avoid prolonged exposure to high humidity during handling. Prior to use, ensure thorough mixing if phase separation occurs, and always follow Dow’s recommended safety precautions including appropriate PPE and ventilation.
