Storage and Shelf Life Conditions

FILCO® 303HP should be stored in closed containers away from direct sun rays, at temperature between +5 and +30°C. In these conditions maximum suggested storage time is 6 months from production, in the original package. After that date product must be rechecked. During storage a slight settlement can take place, which can easily be eliminated by careful stirring. Prevent from freezing.
