Q1: What type of epoxy resins is BC923 compatible with?
A: BC923 is specifically formulated for use with waterborne epoxy resins commonly employed in domestic floor coating systems. It demonstrates good compatibility with standard bisphenol-A and bisphenol-F based water-dispersible epoxy emulsions, supporting stable mixing and efficient crosslinking under ambient curing conditions.
Q2: How does BC923 affect pot life and film formation in waterborne epoxy floor coatings?
A: BC923 provides a balanced reactivity profile—offering sufficient working time for application while enabling robust film formation at room temperature. Pot life typically remains suitable for standard roller or trowel application methods, and the cured film develops good hardness, gloss retention, and resistance to light foot traffic within 24–48 hours under typical indoor conditions.
Q3: Is BC923 suitable for low-VOC or zero-VOC floor coating formulations?
A: Yes—BC923 is a water-based, non-solvent curing agent designed to support environmentally compliant formulations. It contains no added volatile organic compounds (VOCs) and contributes to achieving low-VOC certification when incorporated into properly balanced waterborne epoxy systems.
Q4: Can BC923 be used in tinted or decorative floor systems?
A: Yes—BC923 exhibits excellent clarity and minimal yellowing tendency upon cure, making it well-suited for pigmented, metallic, or quartz-filled decorative floor applications where aesthetic consistency and long-term color stability are important.
