Storage and Shelf Life Conditions

FILCO® 306 should be stored in closed container away from sun rays, at temperatures between 5° C and 30°C. In these conditions, maximum suggested storage time is 12 months from production, in the original package. After that date the product must be rechecked. During storge a slight settlement can take place, which can easily be eliminated by careful stirring.
