Automotive painting operations

Extensive efforts are known to be in progress which may lead to a reduction and even the elimination of solvents used in automotive painting operations. Each coating layer is applied by a different process which may be eiflier a water based coating or a powder coating. An example of a water-based coating for an automotive basecoat can be found... 

The low heat sag values.relate to the ability of fabricated parts to withstand automotive assembly line paint bake-oven cycles— an ability which could eliminate the requirement for a separate offline painting operation and permit use of the same paints used for steel components.

Process Objective UF is used for three principle objectives. First, to fractionate, to pass selectively one component through the membrane with the solvent. Second, to concentrate, to pass the solvent. These two, while different, are related and it is common to purify and concentrate a component siiTuiltaneously. The third objective, quite different, is to produce a solvent stream as a product. An example is the operation of an ultrafilter for producing low-cost permeate. An important apphcation of UF is in the automotive industiy where UF is used to remove water and microsolutes from huge electrophoretic paint tanks for use in rinsing excess paint (dragout) from... 

In the chemical industry and in research alone more than 1700 trade name products and chemicals are used as solvents (Ash and Ash, 1996). The worldwide solvents market is estimated at over 30 billions pounds per year. Solvents are used in a wide range of industries and applications including metal cleaning and degreasing, dry cleaning operations, automotive and aviation fuel additives, paints, varnishes, lacquers, paint removers, plastics and rubber products, adhesives, textiles, printing inks, pharmaceuticals, and food processing.
