Abstract

PURPOSE: A polyurethane resin having an improved sealing effect against fouling matter from the base material, comprising an isocyanate prepolymer obtained by the reaction between a polyether polyol and a polymethylene polyphenyl isocyanate, and a diluting solvent.
CONSTITUTION: A polyether polyol, MW 200W3,000, is used as a polyol component. This compound is reacted with a polymethylene polyphenyl isocyanate to yield an isocyanate prepolymer having a free isocyanate group content of 10W25%, based on the weight of resin solids. Next, the moisture-curing polyurethane resin of the purpose is obtained by diluting the prepolymer with a diluting solvent to form a resin solution having a concentration of, preferably, about 30W60wt%. The diluting solvents which are used include, for example, toluene, ethyl acetate, and methyl isobutyl ketone.
