FIELD: process engineering. n SUBSTANCE: invention relates to method of coating substrates. First stage comprises making substrate. Composition is applied on substrate first side. Proposed composition comprises inorganic compound containing at least one metal and/or semimetal selected from the following group including Sc, Y, Ti, Zr, Nb, V, Cr, Mo, W, Mn, Fe, Co, B, Al, In, Tl, Si, Ge, Sn, Zn, Pb, Sb, Bi or mixes thereof, and at least one element selected from group including Te, Se, S, O, Sb, As, P, N, C, Ga or mixes thereof. Then composition is dried. Now, at least one coat is applied onto substrate first side whereon composition was applied. Composition comprises silane of general formula (Z I )Si(OR) 3 , oxide particles, polymer and initiator. Z I stands for R, OR or Giy (Gly = 3-glycidyl hydroxypropyl). R stands for alkyl residue with 1 to 18 atoms of carbon. R may differ or be equal. Oxide particles are selected from oxides of Ti, Si, Zr, Al, Y, Sn, Zn, Ce or mixes thereof. Coat is dried. Then, at least one protective coat is applied on second side of substrate. Additionally, at least one glue layer may be applied on protective layer. n EFFECT: protection against ambient effects, ruling out substrate top surface deformation. n 38 cl |
