Storage & Handling

Storage and Handling

Store the material in a dry area out of direct sunlight. Prevent exposure to any UV or visible light. Keep containers closed and protect from physical damage. On extended storage, ADDITOL CPK crystalline powder may agglomerate to form solidified lumps. These can be physically broken-up into smaller pieces as needed for use. Such agglomeration does not affect product quality, though lumps of ADDITOL CPK will take longer to dissolve into solution.
