Deinishing involves removing old layers of paint. This involves exposing the paint layer to high or low temperatures, mechanical influences or chemicals, which removes it from the substrate. A variety of different processes are used in practice today. These include the so-called cryogenic process with CO2, in which the paint layer becomes brittle due to the low temperature. Another method is the thermal process. Here, the polymers contained in the paint layer are destroyed by a high temperature. Other processes include scarfing, eddy current coating, pyrolysis, fluidised bed coating, boiling, laser stripping and infrared irradiation. Blasting processes include cleaning with pressurised water jets, compressed air blasting, wet blasting, wet pressure blasting, centrifugal blasting or sand blasting, dry ice blasting and snow blasting. Mechanical processes include sanding, brushing, scraping and wiping to remove the paint.

.Depending on the statutory regulations and DGUV guidelines, it is also important to observe the manufacturer-specific specifications here.
How is the process billed to the customer?
The invoicing for paint stripping is based on weight, i.e. the goods are weighed before and after paint stripping. Billing for the inspection is based on the number of items or time spent and is calculated individually.
How do I measure the paint thickness?The paint thickness is determined using a coating thickness gauge.
Here, coordination with the manufacturers of the components is absolutely necessary.
