HOAT coolants typically mix an OAT with a traditional inhibitor, usually silicates. [32] An example is Zerex G05, which is a low-silicate, phosphate free formula that includes the benzoate inhibitor. [23] A HOAT coolant can have a life expectancy as high as 10 years / 180,000 miles. [32]
The term 'inhibitor' is often used in a general sense to describe any compound used to prevent unwanted polymerisation, however these compounds are often divided into 'retarders' and 'true inhibitors'. A true inhibitor has a well defined induction period during which no noticeable polymerisation takes place. They are consumed during this period ...
Corrosion inhibitors are used in the petroleum industry in several steps, including drilling, production, transportation, and storage of oil and gas. [ 2 ] [ 3 ] They can mitigate different types of corrosion in the petroleum industry, such as generalized corrosion, pitting corrosion, erosion corrosion, stress corrosion, galvanic corrosion ...

At airports, where DEF can sometimes be required for diesel ground service vehicles, its labelling and storage must be carefully managed to avoid accidentally servicing jet aircraft with DEF instead of fuel system icing inhibitor, a mistake that has been blamed for multiple in-flight engine failure and grounding incidents.
An inhibitor can reduce the effectiveness of a catalyst in a catalysed reaction (either a non-biological catalyst or an enzyme).E.g., if a compound is so similar to (one of) the reactants that it can bind to the active site of a catalyst but does not undergo a catalytic reaction then that catalyst molecule cannot perform its job because the active site is occupied.
