Beschreibung
Zusammenfassung:	A threadlocking composition comprising an anaerobically curable component and a curing component for curing the anaerobically curable component; wherein the composition is in flowable particulate form and has a melting point in the range 30-100 °C. The anaerobically curable component may comprise an anaerobically curable monomer and a resin component. The composition may be provided in at least two-part form. The anaerobically curable component is preferably provided in powder form. Preferably the resin component is selected from methacrylated polyurethane resins, novolac resins or higher methacrylated polyester resins. The anaerobically curable monomer preferably comprises at least one acrylate or methacrylate ester group. The composition is preferably solvent-free. Also disclosed is a method of threadlocking two threaded articles together comprising applying said composition to the threads of at least one article so as to fuse it by melting to the threads; subsequently, and optionally after cooling, threading the two articles together so as to initiate anaerobic cure of the threadlocking composition so as to chemically bond the two articles together. An article having said composition applied thereto is also disclosed.
