Storage and Shelf Life Conditions

FILCO® 3 JM must be stored in closed containers away from direct sun rays, at a temperature between + 5°C and + 30°C. In these conditions the maximum suggested storage time is 6 months from production, in the original packaging. After that date the product must be rechecked. During storage a slight settlement can take place, which can easily be eliminated by careful stirring.
