The invention concerns a threaded tubular component intended for drilling and/or working a hydrocarbon well, said tubular component having, at one of its ends (1; 2), a threaded zone (3; 4) formed on its external or internal peripheral surface depending on whether the threaded end is male or female in type, characterized in that the end portion (1; 2) is at least partially coated with a dry film (12), comprising a thermoplastic or thermoset matrix (13) including microcapsules filled with compounds in the liquid form, wherein the compounds are linear polydimethylsiloxanes with a kinematic viscosity in the range 100 to 12500 mm/s at 25°C and with a molecular mass in the range 10000 to 80000 g/mole. |
