Abstract
A method for producing a matrix-containing dry film on a threaded tubular component for drilling or working hydrocarbon wells, by applying a mixture containing a dispersion or an aqueous emulsion of an acrylic copolymer with a solution of an alkaline polysilicate in a liquid state onto a threaded end of the threaded tubular component by spraying at a temperature of from 20° C. to 40° C. thereby obtaining a threaded end coated with a film; drying the threaded end coated with the film; and densifying the film.
