Abstract A flowable anaerobic sealant composition adapted to be applied to a threaded surface which is characterized by being stable prior to curing is provided which composition comprises a polymerizable acrylate ester monomer, a hydroperoxide polymerization catalyst for said acrylate ester monomer in an amount sufficient to cause said monomer to polymerize under anaerobic conditions, a quinone polymerization inhibitor in an amount sufficient to prevent said monomer from polymerizing when standing for long periods of time, an organic sulfimide accelerator in an amount sufficient to increase the rate of polymerization of said monomer under anaerobic conditions, and a plasticizer in an amount sufficient to render the solidified sealant composition relatively non-brittle. Optionally, the sealant composition may also contain a thickening agent in an amount sufficient to render said sealant composition flowable at room temperature, a coloring agent in an amount sufficient to render said sealant composition non-transparent, a viscosity controlling agent in an amount sufficient to permit said sealant composition to readily flow into said threads when applied thereto without excessive runoff, and an effective amount of tetrafluoroethylene polymer as an anti-galling agent.
