- Storage and Shelf Life Conditions
FILCO® 309 should be stored in closed containers away from direct sun rays, at temperature between +15 and +35°C. In these conditions maximum suggested storage time is 12 months from production, in the original package. After that date product must be rechecked. Like all low-molecular-weight epoxies, FILCO® 309 can have formation of Crystals at temperatures below 15°C; in case it happens, product should be re-conditioned by mixing and stirring, following coim adivice.Prevent from freezing – thoroughly mix before use
