  • Laminated glass has long been known for use as safety glass, for example in the automotive industry and in building construction for window and facade cladding elements.
  • Safety glasses are basically subdivided into two different types, the laminated safety glass (LSG) and the single-pane safety glass (ESG).
  • a laminated glass safety glass consists of two glass panes, which are glued together with the interposition of a plastic film or casting resin.
  • Single-pane safety glasses (ESG) in contrast to conventional glasses, are characterized in that they chip in a defined manner in the event of a break-down.
  • very small splinters can arise, which essentially have no sharp-edged areas
  • alternative tempered safety glass can be designed in such a way that very large pieces are produced, which are much easier to handle, in contrast to the aforementioned small splinters.
  • EP 1 195 243 A1 discloses a safety glass which is intended to meet safety-relevant aspects and, in particular, should have a high splinter bond and a high bending strength, so that the possibility of, in particular, a mechanical see after treatment is opened.

  • the object with regard to the method is achieved in that the resin is a liquid, UV-resistant LC polyurethane material which essentially comprises a prepolymer based on an aliphatic isocyanate having low monomeric proportions and wherein a temperature for curing the Resin to about 30 0 C is provided.
  • the core idea of the invention is to use a one-component (1K) polyurethane material for coating glass instead of a two-component (2K) polyurethane material.
  • This has the advantage that annoying mixing of the resin with the hardener, which often contains viscose components, is omitted before the application. It cures solely by the existing humidity. Since the resin is moisture-curing, it remains elastic, which may be important for the after-treatment on facades, among other things.
  • a further, surprising advantage is that aliphatic isocyanates can be used as the resin material, which have a UV resistance in combinations according to the invention.

  • the surface of the resin is shiny.

  • This safety glass according to the invention is cheaper to produce than conventional laminated safety glass, since only one resin layer has to be applied to a carrier glass and the resin cures at ambient temperatures without the application of heat energy.
