Mo-3831 LeA 28,854 POLYOLEFIN TANKS INTERNALLY COATED WITH MOISTURE HARDENING COATING COMPOSITIONS AND A PROCESS FOR THEIR PREPARATION ABSTRACT OF THE DISCLOSURE The present invention relates to a process for coating the inside of a polyolefin plastic tank for storing liquid hydrocarbons by I) coating the inside of the tank with i moisture-hardening, coating composition having a viscosity at 23°C of 60 to 2,500 mPa.s and containing a) at least one polyisocyanate containing biuret, isocyanurate, uretdione and/or allophanate groups which is liquid at room temperature, is prepared from hexamethylene diisocyanate and has an isocyanate content of at least 10% by weight and b) 0 to 5% by weight, based on the weight of the coating composition, of an organic solvent for polyiso- cyanates which is inert towards isocyanate groups and II) curing the coating under the influence of moisture. The present invention also relates the resulting coated polyolefin plastic tanks for storing liquid hydrocarbons, in particular gasoline or diesel fuel.
