Q1: What is the primary functional role of KCW NC-3000H in epoxy formulations?
A: KCW NC-3000H 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-3000H compatible with common amine-based hardeners?
A: Yes — it exhibits broad compatibility with aliphatic, cycloaliphatic, and aromatic amine hardeners, as well as anhydride curing systems, supporting consistent reactivity and homogeneous network formation during cure.
Q3: How does KCW NC-3000H affect the final cured film properties compared to non-diluted epoxy systems?
A: When used at recommended levels, it maintains good mechanical strength, chemical resistance, and adhesion while enhancing flow and reducing entrapped air — though excessive loading may slightly lower heat distortion temperature and glass transition.
Q4: What are the recommended storage conditions for KCW NC-3000H?
A: Store in tightly sealed original containers under cool, dry, and well-ventilated conditions, away from direct sunlight and strong oxidizing agents. Prolonged exposure to elevated temperatures or moisture should be avoided to preserve reactivity and shelf life.
