Q1: What type of epoxy systems is BC902 designed for?
A: BC902 is specifically formulated as a curing agent for waterborne epoxy resin systems used in domestic and light-commercial flooring applications, including self-leveling underlayments, decorative coatings, and protective topcoats where low VOC and user-friendly handling are required.
Q2: Is BC902 compatible with common waterborne epoxy resins?
A: Yes, BC902 demonstrates good compatibility with standard waterborne epoxy dispersions, particularly those based on bisphenol-A or bisphenol-F backbone chemistries. Compatibility should be verified through small-scale formulation trials to ensure optimal pot life, film formation, and final cure performance.
Q3: How does BC902 affect pot life and curing speed under typical indoor conditions?
A: BC902 provides a balanced reactivity profile—offering sufficient working time (pot life) for application at room temperature while enabling practical through-cure within 24–48 hours under standard ambient conditions. Cure development accelerates with moderate temperature elevation and appropriate humidity control.
Q4: Does BC902 contribute to film hardness or chemical resistance in the cured system?
A: When properly formulated and fully cured, BC902 helps deliver good surface hardness, abrasion resistance, and tolerance to household cleaning agents and mild chemicals—key requirements for residential floor coatings. Final performance depends on the overall formulation, mixing ratio, and curing environment.
Q5: Can BC902 be used in tinted or pigmented waterborne epoxy flooring systems?
A: Yes, BC902 is compatible with common pigment dispersions and colorants used in waterborne architectural coatings. It does not interfere with color stability or dispersion integrity when incorporated according to recommended addition protocols and shear-controlled mixing practices.
