Composition for the cold preparation of composite materials for adhesive bonding

The invention concerns inhibitor compositions based on fatty sulphydryl acid and poly(ethyleneamino)imidazoline salts for considerably reducing the corrosive effect of carbon brine on iron and ferrous metals. These compositions are as efficient when the corrosive medium is driven with a high flowrate and in biphasic brine/oil medium.
