    摘要: The present invention provides aqueous concentrated corrosion inhibition formulations suitable for addition to depleted antifreeze/coolant compositions or corrosive water that use a mixture of polymeric polycarboxylates, azoles, nitrate salts, phosphates, stabilized silicates and transition metal compounds which reduces the corrosion rate and is effective at relatively low concentrations. The formulations are particularly suitable for automotive applications.
