What are the storage conditions of FPR Resin components, e.g. % moisture, maximum temperature, and shelf-life ?
Epoxy component (moisture-insensitive): shelf-life of one year at room temperature (up to 35 °C) in closed containers. Isocyanate component (water and moisture-reactive): shelf-life typical for liquid MDI isocyanates, i.e., 6 months at maximum 20°C in the original, sealed drums, or in partially empty containers tightly closed after dry-air or dry-nitrogen blanketing. FPC Catalysts (moisture-insensitive, or just slightly hygroscopic): shelf-life of one year at room temperature (up to 35°C) in the original, sealed containers; 6 months in partially empty, tightly closed cans or drums. • Are uncatalyzed isocyanate-epoxy blends stable over time ? Isocyanate-epoxy mixtures must be prepared prior to their use, and can only be stored for limited periods of time without significant, spontaneous viscosity increases. Suggested storage time at room temperature for un-catalyzed isocyanate-epoxy blends: 48 hours maximum (typically, max. 36 hours at 20-25 °C; max. 12 hours at 30-35 °C).
