A method for inhibiting corrosion in a cooling system, wherein the cooling system comprises a metal surface and a coolant, the method comprising the step of contacting a mixture comprising:
- an organic amine;
- a phosphoric acid and/or inorganic phosphate;
- and
- a metal oxide and/or a metal hydroxide,
- with the coolant,
- thereby inhibiting corrosion in said cooling system.
A method for inhibiting corrosion of a reinforcement steel in concrete, wherein the method comprising the step of adding an anti-corrosive to a concrete mixture comprising:
- an organic amine;
- a phosphoric acid and/or inorganic phosphate;
- and
- a metal oxide and/or a metal hydroxide,
- thereby inhibiting corrosion of the reinforcement steel in concrete.
A water-based coolant comprising:
- an organic amine;
- a phosphoric acid and/or inorganic phosphate;
- and
- a metal oxide and/or a metal hydroxide.
A concrete comprising:
- an organic amine;
- a phosphoric acid and/or inorganic phosphate;
- and
- a metal oxide and/or a metal hydroxide.
