PROCESSES FOR APPLYING FLUENT MATERIALS TO SURFACES, IN GENERAL (conveying articles or workpieces through baths of liquid B65G, e.g. B65G49/02)

Introduced: July 1974

Description

This subclass covers processes and methods for depositing liquid, semi-liquid, or atomized materials onto surfaces through various application techniques. It encompasses coating, painting, spraying, dipping, rolling, spreading, and similar deposition methods, excluding those involving atomization covered by B05B. The classification applies across diverse industries including construction, automotive, aerospace, and manufacturing, where surface treatment, protection, or functional modification is required.

Glossary

Coating coatings 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 fluidised-bed techniques 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 particulate material Solid materials in the form of very small pieces, e.g. powders, granules, short fibres or chips.
