Abstract
The present invention relates to formulations for inhibiting the corrosion of the metals used in the oil industry, and more generally in all types of industries for drilling for fossil compounds or ores, such as gas or oil. The corrosion-inhibiting formulations are stable during storage, and have improved properties due to the presence of at least one compound having at least one triazine unit. The invention also relates to the use of at least one compound comprising at least one triazine unit in a corrosion-inhibiting formulation, as well as to the use of said corrosion-inhibiting formulation in the oil, gas and mining industry.
