Storage and Transport
The formulation of CF7 contains an inhibitor package designed to protect several metal alloys from accelerated corrosion and deterioration (e.g., cracking). The inhibitor package consists of fully dissolved compounds which, when exposed to metal alloys such as plain carbon or low alloy steels, will form a barrier on the alloy surface to prevent accelerated corrosion.
To maintain the full effectiveness of the inhibitor package Cryotech recommends shipping and storage of CF7 in non-metal containers such as polyethylene. In cases where this is not possible, shipment and storage can be accomplished with carbon, low alloy, or stainless steel containers. Storage and shipment containers should be strong enough to hold 10.68 lbs. per gallon of CF7, which is 28% heavier than water.
Shipping and storage in carbon or low alloy steel containers does not represent a major concern. However, the customer must be aware that this may result in depletion of the inhibitor concentration. The amount of depletion will depend on material composition, surface condition, and surface area.
When shipment or storage in carbon or low alloy containers is necessary, the container must be clean and free of rust and surface deposits. Rust and surface deposits (or scale) may become dislodged or dissolved and result in fluid degradation and discoloration. Additionally, tanks or containers which have been used for other materials must be drained and, at a minimum, rinsed, to remove the material before introducing CF7.
Note: Residue of chloride based deicer (especially CaCl2 and MgCl2) must be removed prior to filling. Avoid galvanized materials in piping and storage systems. Potassium acetate is known to have a relatively slow reaction with zinc-coated materials. This is not an issue for roadway appurtenances where exposure time is limited.
