Lacquer being sprayed onto a cabinet

A coating is a covering that is applied to the surface of an object, or substrate. [1] [2] The purpose of applying the coating may be decorative, functional, or both. [3] Coatings may be applied as liquids, gases or solids e.g. powder coatings.

Paints and lacquers are coatings that mostly have dual uses, which are protecting the substrate and being decorative, although some artists paints are only for decoration, and the paint on large industrial pipes is for identification (e.g. blue for process water, red for fire-fighting control) in addition to preventing corrosion. Along with corrosion resistance, functional coatings may also be applied to change the surface properties of the substrate, such as adhesion, wettability, or wear resistance. [4] In other cases the coating adds a completely new property, such as a magnetic response or electrical conductivity (as in semiconductor device fabrication, where the substrate is a wafer), and forms an essential part of the finished product. [5] [6]

A major consideration for most coating processes is controlling coating thickness. Methods of achieving this range from a simple brush to expensive precision machinery in the electronics industry. Limiting coating area is crucial in some applications, such as printing.

"roll-to-roll" or "web-based" coating is the process of applying a thin film of functional material to a substrate on a roll, such as paper, fabric, film, foil, or sheet stock. [7]

Applications

Coatings can be both decorative and have other functions. [4] [8] A pipe carrying water for a fire suppression system can be coated with a red (for identification) anticorrosion paint. Most coatings to some extent protect the substrate, such as maintenance coatings for metals and concrete. [9] A decorative coating can offer a particular reflective property, such as high gloss, satin, matte, or flat appearance. [10]

A major coating application is to protect metal from corrosion. [11] [12] [13] [14] [15] [16] Automotive coatings are used to enhance the appearance and durability of vehicles. These include primers, basecoats, and clearcoats, primarily applied with spray guns and electrostatically. [17] The body and underbody of automobiles receive some form of underbody coating. [18] Such anticorrosion coatings may use graphene in combination with water-based epoxies. [19]

Coatings are used to seal the surface of concrete, such as seamless polymer/resin flooring, [20] [21] [22] [23] [24] bund wall/containment lining, waterproofing and damp proofing concrete walls, and bridge decks. [25] [26] [27] [28]

Most roof coatings are designed primarily for waterproofing, though sun reflection (to reduce heating and cooling) may also be a consideration. They tend to be elastomeric to allow for movement of the roof without cracking within the coating membrane. [29] [30] [31]

Wood has been a key material in construction since ancient times, so its preservation by coating has received much attention. [32] Efforts to improve the performance of wood coatings continue. [33] [34] [35] [36] [37]

Coatings are used to alter tribological properties and wear characteristics. [38] [39] These include anti-friction, wear and scuffing resistance coatings for rolling-element bearings [40]

Other

Other functions of coatings include:

Analysis and characterization

Numerous destructive and non-destructive evaluation (NDE) methods exist for characterizing coatings. [57] [58] [59] [60] The most common destructive method is microscopy of a mounted cross-section of the coating and its substrate. [61] [62] [63] The most common non-destructive techniques include ultrasonic thickness measurement, X-ray fluorescence (XRF), [64] X-Ray diffraction (XRD) [65] and micro hardness indentation. [66] X-ray photoelectron spectroscopy (XPS) is also a classical characterization method to investigate the chemical composition of the nanometer thick surface layer of a material. [67] Scanning electron microscopy coupled with energy dispersive X-ray spectrometry ( SEM-EDX, or SEM-EDS) allows to visualize the surface texture and to probe its elementary chemical composition. [68] Other characterization methods include transmission electron microscopy (TEM), atomic force microscopy (AFM), scanning tunneling microscope (STM), and Rutherford backscattering spectrometry (RBS). Various methods of Chromatography are also used, [69] as well as thermogravimetric analysis. [70]

Formulation

The formulation of a coating depends primarily on the function required of the coating and also on aesthetics required such as color and gloss. [71] The four primary ingredients are the resin (or binder), solvent which maybe water (or solventless), pigment(s) and additives.[ example needed] [72] [73] Research is ongoing to remove heavy metals from coating formulations completely. [74]

For example on the basis of experimental and epidemiological evidence, it has been classified by the IARC (International Agency for Research on Cancer) as a human carcinogen by inhalation (class I) ( ISPESL, 2008). [75]

Roll-to-roll coating processes

Common roll-to-roll coating processes include:

  • Air knife coating
  • Anilox coater
  • Flexo coater
  • Gap Coating
    • Knife-over-roll coating
  • Gravure coating
  • Hot melt coating- when the necessary coating viscosity is achieved by temperature rather than solution of the polymers etc. This method commonly implies slot-die coating above room temperature, but it also is possible to have hot-melt roller coating; hot-melt metering-rod coating, etc.
  • Immersion dip coating
  • Kiss coating
  • Metering rod (Meyer bar) coating
  • Roller coating
  • Silk Screen coater
    • Rotary screen
  • Slot Die coating - Slot die coating was originally developed in the 1950s. [78] Slot die coating has a low operational cost and is an easily scaled processing technique for depositing thin and uniform films rapidly, while minimizing material waste. [79] Slot die coating technology is used to deposit a variety of liquid chemistries onto substrates of various materials such as glass, metal, and polymers by precisely metering the process fluid and dispensing it at a controlled rate while the coating die is precisely moved relative to the substrate. [80] The complex inner geometry of conventional slot dies require machining or can be accomplished with 3-D printing. [81]
  • Extrusion coating - generally high pressure, often high temperature, and with the web travelling much faster than the speed of the extruded polymer
    • Curtain coating- low viscosity, with the slot vertically above the web and a gap between slot-die and web.
    • Slide coating- bead coating with an angled slide between the slot-die and the bead. Commonly used for multilayer coating in the photographic industry.
    • Slot die bead coating- typically with the web backed by a roller and a very small gap between slot-die and web.
    • Tensioned-web slot-die coating- with no backing for the web.
  • Inkjet printing
  • Lithography
  • Flexography
