Division BAT 24 In order to reduce the consumption of solvents, other raw materials and energy, as well as to reduce VOC emissions, BAT is to use one or a combination of the coating systems given below.
United Kingdom
| Coating system | Description | Applicability | |
|---|---|---|---|
| (a) | Mixed (SB-mix) coating | A coating system where one coating layer (primer or base coat) is water-based. | Only applicable to new plants or major plant upgrades. |
| (b) | Water-based (WB) coating | A coating system where the primer and base coat layers are water-based. | |
| (c) | Integrated coating process | A coating system which combines the functions of primer and base coat and is applied by spray coating in two steps. | |
| (d) | Three-wet process | Coating system where the primer, base coat and clear coat layers are applied without intermediate drying. The primer and base coat may be solvent-based or water-based. | |
Table 7
BAT-associated emission levels (BAT-AELs) for total emissions of VOCs from the coating of vehicles
| The BAT-AELs refer to emissions from all process stages, carried out at the same installation from the electrophoretic coating or any other kind of coating process up to and including the final wax and polish of the topcoat, as well as solvents used in cleaning of production equipment, both during and outside the production period. | ||||
| The surface area is defined as set out in Part 3 of Annex VII to Directive 2010/75/EU. | ||||
| Parameter | Vehicle type | Unit | BAT-AELf1(Yearly average) | |
|---|---|---|---|---|
| New plant | Existing plant | |||
| Total VOC emissions as calculated by the solvent mass balance | Passenger cars | g VOCs per m2 of surface areaf2 | 8–15 | 8–30 |
| Vans | 10–20 | 10–40 | ||
| Truck cabins | 8–20 | 8–40 | ||
| Trucks | 10–40 | 10–50 | ||
| Buses | < 100 | 90–150 | ||
The associated monitoring is given in BAT 10.
