Abstract:
A thin adhesive lubricating composition that can cover at least one thread and a screwing abutment of a threaded element of a component of a tubular threaded joint. The screwing abutment can bear against another abutment of another component of the tubular threaded joint in a terminal make up phase. The lubricating composition includes a matrix in which there is dispersed at least one braking additive selected to impart thereto, in addition to lubrication, a coefficient of friction to make it possible to obtain a torque on shoulder resistance value at least equal to a threshold value.
