Shelf Life and Storage

Levasil® CB30 should be transported and stored at a temperature of 5 - 35°C (40 - 95ºF). If the silica dispersion is allowed to freeze, the silica will irreversably precipitate. For bulk storage, the tank should be sealed and constructed of plastic, fiberglass reinforced plastic, or stainless steel. For packaged goods, any translucent packages should be stored out of direct sunlight or bright light. Under recommended conditions, Levasil® CB30 has a shelf life of twelve months after production
