The present invention relates to a method for coating substrates, including applying a composition to a first side of the substrate, the composition containing an inorganic compound, drying the applied composition, applying at least one coating to the first side of the substrate to which the composition is applied, the coating containing a silane, drying the applied coating, and applying at least one barrier layer to a second side of the substrate.

Method for coating substrates and carrier substrates

A method for coating substrates, containing a) applying a composition to a first side of a substrate, the composition containing an inorganic compound and the inorganic compound containing a metal such as Sc, Y, Ti, Zr, Nb, V, Cr, Mo, W, Mn, Fe, Co, B, Al, In, Tl, Si, Ge, Sn, Zn, Pb, Sb, or Bi, and an element such as Te, Se, S, O, Sb, As, P, N, C, or Ga, b) drying the composition, c) applying a coating to the first side of the substrate, the coating containing a silane, oxide particles of Ti, Si, Zr, Al, Y, Sn, Zn, Ce or mixtures thereof, a polymer and an initiator, d) drying the coating, e) applying a barrier layer to a second side of the substrate, and f) drying the barrier layer to form a dry barrier layer.

A process for the production or coating of granules in a fluidized bed, which includes heating a fluidized-bed gas to produce the fluidized bed, and applying a liquid medium containing a granule-forming or coating-forming compound, or at least one reaction component therefore, by spraying particles located in the fluidized bed and at a same time vaporizing an organic solvent contained in the liquid medium, said particles having a smaller mean diameter than that of particles to be produced. The process also includes partial condensation of an organic solvent from at least a portion of a fluidized-bed waste gas leaving the fluidized bed, and re-heating the fluidized bed-gas leaving the condensation device and reintroducing the re-heated gas into the fluidized bed.
