An isocyanate prepolymer composition having an extended potlife, without the addition of an excess amount of benzoyl chloride is disclosed. The isocyanate prepolymer composition includes an isocyanate prepolymer formed from the reaction of a polyhydroxyl compound with an excess of a polyisocyanate. The composition further includes included a plasticizer, and a phosphate ester. The phosphate ester has at least one acidic hydrogen and pentavalent phosphorous atoms. Preferably, the composition also includes very low levels of benzoyl chloride and an oil.
