Abstract
The invention relates to a new process for the shatterproof coating of glass surfaces by coating the surfaces with a coating composition based on a two-component system reacting fully to form a polyurethane, the glass surfaces to be coated being coated before application of the coating composition with a physically drying priming lacquer containing a silane adhesion promoter and a catalyst which accelerates hardening of the coating composition and, as binder, a polyurethane polyurea which has a linear molecular structure and which is soluble in lacquer solvents.
