Fostex 40
ACID DESCALING FOR PRE-PHOSPHATE PROCESS
FOSTEX 40 is a concentrated solution of phosphoric acid formulated for removing heavy heat scale on hot rolled steel. It should be used diluted but can be used neat (concentrate) depending on the level of descaling required. FOSTEX 40 surfactant package is similar to our FOSTEX ST so it is capable of wetting-out the steel surface regardless of soil contamination.
