precote 05


precote 05 is a nonreactive, film-forming dispersion with mineral solids for coating threaded parts. It is a physiologically harmless precoating for immediate sealing of cylindrical and conical threads. The dried film is tack-free.


On threaded parts (cylindrical/cylindrical and cylindrical/conical combinations) like screws, studs, plugs and pipe threads for sealing against gases and liquids. A special inhibitor avoids corrosion also on brass fittings.

Forms a dry and tack-free film. Seals immediately after assembly. Is physiologically harmless in liquid and coated condition. Threaded parts can be preapplied long time before assembly(oT coating machine) Thread friction values are not altered. Avoids corrosion in the threaded connection. Can be applied on all threaded materials - also on plastics. Good chemical resistance.
