Airports substituting formate for acetate on brake oxidation concerns
Alkali metal salts catalyse oxidation of carbon brake discs, which airframe manufacturers have addressed in service guidance, and formate is the less aggressive of the two runway de-icing chemistries on that measure. Airports operating large carbon-braked fleets have been converting through recent tender cycles, and European operators moved first. Roughly 31% of potassium formate demand now goes to runway operations. The substitution converts share of an existing de-icing market rather than creating new demand, which is why it outruns air traffic growth comfortably. North American and Asian adoption still lags European practice by a considerable margin.
