Process for the coating of glass surfaces

摘要: A process for the coating of glass surfaces with a transparent, duroplastic protective layer more than 50 microns which comprises first treating clean surface an aqueous or alcoholic silane skim coat, drying treated and then dry paste aliphatic cycloaliphatic diisocyanates mixtures thereof reaction products water in mole ratio 2:≦1 mixture hydroxy-group-containing compounds consisting 40-80 wt. %, trifunctional, polyester polyols made dicarboxylic acids triols, diols tricarboxylic acids, average molecular weight 300 to 1400, 15-50 % bifunctional, from diols, 400 2000 and, if necessary, 2.5-25 thereof, respect total quantity polyols, optionally hardening coated further added heat.
