B05D - Definition
This subclass covers:
Processes for applying liquids or other fluent materials to a surface or part of a surface, in general, by any mechanical or physical method and particularly processes producing a uniform distribution of liquids or other fluent materials on a surface.
Pretreatment of surfaces to which liquids or other fluent materials are to be applied.
After-treatment of applied coatings.
Processes for applying liquids or other fluent materials to surfaces to obtain special surface effects, finishes or structures.
Processes specially adapted for applying liquids or other fluent materials to particular surfaces (e.g. to macromolecular substances, to wood, to leather, to metal, to wires, to internal surfaces).
Processes specially adapted for applying particular liquids or other fluent materials (e.g. processes adapted for the application of lacquers or varnishes)
Relationship between large subject matter areas
Subclass B05B relates to spraying, sprinkling and atomising apparatus, including nozzles, for the release or projection of drops or droplets into the atmosphere or into a chamber to form a mist or the like. The material to be sprayed or atomised may be suspended in a stream of gas or vapour. Accordingly, B05B covers spray heads, sprinkling apparatus, electrostatic spraying apparatus, hand-held spraying apparatus, spraying plants (e.g. spray booths), delivery control means associated with such apparatus, and the like. Also covered are means for heating, mixing or pressurising of the materials to be sprayed, sprinkled or atomised. Whilst B05B covers spraying apparatus, the processes for applying liquids and other fluent materials to surfaces by spraying (including electrostatic spraying processes) are covered by groups B05D 1/02-B05D 1/14.
Subclass B05C relates to apparatus for applying liquids or other fluent materials to surfaces in general. This subject matter generally relates to contact methods e.g. spreading, pouring, dipping, rubbing, using rollers, using fluidised-bed techniques etc. B05C also relates to apparatus for projecting liquids or other fluent materials onto surfaces (B05C 5/00) or to the inside of hollow work (B05C 7/02), and further to apparatus specially adapted for the projection of particulate material onto surfaces (B05C 19/04). ‘Projection’ relates to the application of a continuous stream of liquid or other fluent material to a surface, where the stream is not divided into droplets or a cloud of particulate material as by the apparatuses covered by B05B. Apparatus for application of particulate materials to surfaces using fluidised-bed technique is classified in B05C 19/02, whilst surface dip-coating processes using fluidised beds are covered by B05D 1/22.

In this subclass, 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. |
