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. Corrosion
Because CF7 is acetate based, it is compatible with most materials and is generally considered non-corrosive. Special corrosion inhibitors have been added to provide the same level of protection as E36, Cryotech’s airport approved liquid deicer.
Avoid CF7 Use
- On low quality or non air-entrained concrete
- In direct application to galvanized metals
- In close proximity to non-watertight electrical systems
- In mixture with liquid chloride deicers like calcium chloride
Maintenance Dispensing Equipment *
- External surfaces of equipment used to dispense CF7 should be routinely rinsed with warm water or a high-pressure wash to prevent buildup of the fluid and other contaminants associated with winter maintenance operations. A thorough high-pressure washing with warm soapy water is recommended as equipment is removed from service after the deicing season.
- Diluted CF7 biodegrades naturally when exposed to air and other contaminants. This process quickens in warmer temperatures. Frequent rinsings will prevent any buildup that could result in formations of unsightly biological growth and superficial staining and pitting of some material.
- Undiluted CF7 kept in closed containers with minimal exposure to air does not degrade and may be stored indefinitely.
Applying liquid deicers to dry pavement will reduce friction between tires and the pavement surface. For this reason alone, user training is important prior to initial use.
