ABSTRACT:
A thermosetting polyurethane resin which when used as a one-pack surface-protective coating agent for glass bottles, inorganic vessels, and the like exhibits excellent mechanical strength, appearance, and water resistance at sterilization temperatures of about 90.degree. C. is obtained by interacting: (a) 10 to 40% by weight of at least two polyoxyalkylene polyols based on the weight of the nonvolatile matter of the thermosetting polyurethane resin, said at least two polyoxyalkylene polyols including 1 to 8% by weight relative to the nonvolatile matter of the thermosetting polyurethane resin of a nonionic surface active agent selected from the group consisting of a polyoxyethylene glycol or a polyoxyethylene-polyoxypropylene glycol, and mixtures thereof, (b) a monofunctional isocyanate-blocking agent, (c) a chain-elongating agent, (d) a cross-linking agent, and (e) a mixture of methylene-bis (4-cyclohexylisocyanate) and iso-phorone diisocyanate at a molar ratio in the range of from 1:0.3 to 1:1.5.
