Coating processes for specific application should be classified in the application field first, they should only be classified in B05D if they have a more general interest.
In this place, the following terms or expressions are used with the meaning indicated:
Coating | The applied material. A coating may be a solidified layer originally applied as a liquid (e.g. dried paint) or a layer of material which, once applied, remains in a liquid or semi-liquid state (e.g. lubricant). |
Flocking | The deposition of fibre particles ('flock') upon a surface where the particles land non-parallel to the surface. The process may be facilitated by the application of electrostatic charge to the flock to cause its attraction to an adhesive-coated surface ('electrostatic flocking'). This results in the fibres standing perpendicular to the surface. |
Fluidised-bed technique | A technique used to cause dry particulate material to behave like a fluid. This is commonly achieved by the introduction of a pressurised fluid into the material and promotes a high degree of contact between the fluid and material. |
Liquid or fluent | designates materials which can flow, e.g. liquids, including solutions, dispersions and suspensions, as well as semi-liquids, pastes, melts and particulate materials. |
Particulate materials | Solid materials in the form of very small pieces, e.g. powders, granules, short fibres or chips. |
Langmuir-Blodgett films (LB) | Contains one or more monolayers of an organic material, deposited from the surface of a liquid onto a solid by immersing (emersing) the solid substrate into (or from) the liquid, the layer being compressed before deposition |
SAM | Self assembled monolayers that are formed spontaneously by adsorption of amphifunctional molecules at solid-liquid and solid-gas interfaces, forming organised molecular assemblies |
