The flow coating process is one in which a flow of paint is hosed onto the article, the excess of paint being drained off and collected for further use. The hosing flushes the paint into awkward corners and difficult inaccessible parts which become coated more thoroughly than is possible with normal spray or brush application.

Curtain coating is a variation of flow coating in which the article to be painted is supported on a moving belt and passes through a falling certain of paint or lacquer. Strip coating and roller coating are processes which involve coating flat surfaces by transferring paint from a roller to the surface in a continuous process and may be used on steel, aluminium, wood, chipboard, etc. The coated material may then be fabricated and has found uses in motor cars, building equipment, domestic appliances, packaging, caravans and many miscellaneous smaller manufacturing applications.

Paint is also applied by ‘silk screen' method and 'litho printing' method, for areas like can coatings and label. In silk screen processes, paint is forced through a sheet of silk or metal gauze, areas of which are made impervious to paint by, for example, attaching a stencil. The screen is placed over the article, paint squeezed or rubbed through the screen, leaving the pattern of the article. Litho printing transfers paint from patterned rollers to selected parts of the article.

In production line processes, curing of these paints and inks needs to be rapid. Currently the system used for some soft drink cans uses high intensity UV light and can cure the paint in less than 0.2 seconds.

Electro-deposition of paint has been looked at in some detail in the motor manufacturing process. This process appears to have great potential because of its efficient and economical usage increased durability and environmental advantages of very low emissions and lack of flammability hazards.
