Corrosion inhibitor for cellulosic insulation

摘要

This invention relates to a process for limiting the corrosive nature of cellulosic insulation which has been treated with a fire-retardant composition, by applying to the insulation an effective amount of an aqueous corrosion inhibiting solution. The corrosion inhibiting solution comprises an amine or alkali metal salt of an aromatic triazole, and an amine or alkali metal salt of an organic phosphate ester acid.
