The paint is off: even firmly adhering layers or multi-layered old coatings are completely removed

One of the most important tasks of blasting technology is found in the field of decoating technology: the removal of material is especially important for surface treatment. The tasks in the field of decoating technology are manifold and depend on the layers involved, their thickness and composition, as well as the material of the workpiece and the further processing of the surface. Using modern blasting technology, mechanical processes can be used to reliably and reproducibly perform tasks from decoating technology.

Decoating technology cleans the surface

Blasting technology is used to remove defined layers down to the substrate material without changing the surface shape. According to this definition, decoating technology is important for the cleaning of surfaces in compliance with DIN 8580. In subgroup 3.6, the aim of cleaning is to separate unwanted layers from the surface of the workpieces. Blasting technology is thus one of the mechanical processes of decoating technology.

Blasting technology removes paint, rust or adhesions

Which blasting technique is used depends on the type of coating and the workpiece itself. For example, decoating technology can be used to remove paint layers from metallic surfaces by blasting. But also the removal of a rust layer, for example from a steel beam, is part of the decoating technology remit. Stuck roller skin, epoxy resin coatings or multi-layer paint applications can also be removed by the blasting technique - right into corners and angles that are difficult to access. For the further processing of workpieces it can be important to remove protective layers such as oil or grease. Blasting technology removes these layers and, if necessary, roughens the surface of the workpieces so that paints or varnishes adhere particularly well afterwards.

Summary: Blasting technology fulfils the tasks of decoating technology when it comes to cleaning the surfaces of workpieces. These can be surfaces covered by rust, scale or mill scale, but also surfaces with coatings, for example thermally sprayed, hot-dip galvanised, electrogalvanised or other coatings.
