The process of de-varnishing or removal of paint (varnish) occurs as a result of a combination of chemical decomposition and the physical process of dissolving the varnish binder. Removal of varnish (paint) takes place by bathing in a chemical agent. The duration of this process depends on the type and thickness of the coatings, as well as the method of applying the coatings (powder paint shop, KTL paint shop). We remove varnish coatings and rinse the details. The advantage of the chemical cleaning of metals process is the speed and the ability to process details that cannot be pyrolysed or shot blasted.
