Q1: What is the primary functional role of KCW NC-3000 in epoxy formulations?
A: KCW NC-3000 is a reactive liquid diluent designed to reduce viscosity and improve processability of standard bisphenol-A or bisphenol-F based epoxy resins without significantly compromising crosslink density or thermal performance.
Q2: Is KCW NC-3000 compatible with common amine-based curing agents?
A: Yes — it demonstrates good compatibility with aliphatic, cycloaliphatic, and aromatic amines, as well as anhydride hardeners, enabling broad formulation flexibility for coatings, adhesives, and composites.
Q3: How does KCW NC-3000 compare to non-reactive diluents in terms of final cured properties?
A: Unlike non-reactive diluents, KCW NC-3000 participates in the curing reaction, helping retain mechanical strength, chemical resistance, and glass transition temperature in the final network — especially when used at moderate dosage levels.
Q4: What are the recommended storage conditions for KCW NC-3000?
A: Store in tightly sealed original containers under dry, cool conditions (below 30 °C) and protected from moisture and direct sunlight. Prolonged exposure to elevated temperatures or humidity may affect shelf life and handling characteristics.
