ODS-FREE CORROSION INHIBITORS/MOISTURE DISPLACERS
|
|
||||||||||||
| Overview: |
Both MIL-C-85054 and MIL-C-81309 Corrosion Preventive Compounds (CPCs) have been reformulated to remove ODSs from their formulations. Moisture displacement is one of the key factors in preventing and inhibiting corrosion and have typically used ODS formulations in the past. ODSs have long served in corrosion inhibitor product formulations functioning not only to displace moisture, but also serving as the propellant for aerosol products. Military activities can continue to use ODS formulations until all existing stocks of these materials are exhausted. New procurements of CPCs will not contain ODSs. Caution should be taken when using the new formulations since many are flammable products. Examples of other ODS-free, corrosion inhibitors are Dinitrol AV100D, Starrett M.1 Oil, and PEN-T. Dinitrol AV100D is a heavy duty compound, with extremely good water displacement, and corrosion resistance, even at elevated temperatures. It leaves a tack-free, firm coat. Starrett M.1. Oil is an all-purpose lubricant with very good corrosion preventative capabilities. It leaves a protective wax coating as it dries. PEN-T is a hydrocarbon based cleaner and lubricant, with excellent penetrant abilities. |

| Compliance Benefit: |
Use of ODS-free corrosion inhibitors/moisture displacers will help facilities meet the requirements under 40 CFR 82, Subpart D and Executive Order 12843 which requires federal agencies to maximize the use of safe alternatives to Class I and Class II ozone depleting substances, to the maximum extent practicable. In addition, the elimination of CFC-113 at the facility decreases the possibility that the facility will meet any of the reporting thresholds for that chemical under 40 CFR 370 and EO 12856. Chemicals used as substitutions should be reviewed for SARA reporting issues. The compliance benefits listed here are only meant to be used as a general guideline and are not meant to be strictly interpreted. Actual compliance benefits will vary depending on the factors involved, e.g. the amount of workload involved.
