FIELD: performing operations.
SUBSTANCE: group of inventions relates to protected substrates and to methods of protecting substrates. Protected substrate comprises a flat substrate having a surface and a burnt temporary protective layer placed over at least a portion of said surface. Burnt temporary protective layer includes a polyurethane layer, an epoxy layer or a combination thereof. Method of removal of burnt temporary protective layer from substrate with coating includes removal of burnt temporary protective layer from surface by burning of burnt temporary protective layer to produce unprotected substrate.
EFFECT: high efficiency of protecting substrates.
