[[SIGMA]LdjDdj will be zero if no VOC solvent is added to the coatings, as received].
Application method | Transfer efficiency |
Air Atomized Spray (waterborne coating) | 0.39 |
Air Atomized Spray (solvent-borne coating) | 0.50 |
Manual Electrostatic Spray | 0.75 |
Automatic Electrostatic Spray | 0.95 |
Electrodeposition | 1.00 |
The values in the table above represent an overall system efficiency which includes a total capture of purge. If a spray system uses line purging after each vehicle and does not collect any of the purge material, the following table shall be used:
Application method | Transfer efficiency |
Air Atomized Spray (waterborne coating) | 0.30 |
Air Atomized Spray (solvent-borne coating) | 0.40 |
Manual Electrostatic Spray | 0.62 |
Automatic Electrostatic Spray | 0.75 |
If the owner or operator can justify to the Administrator's satisfaction that other values for transfer efficiencies are appropriate, the Administrator will approve their use on a case-by-case basis.
Then calculate or select the appropriate limit according to § 60.392(a) .
