The DELTA®-CLEAN ETCHANT 20 is a fluid, highly concentrated surfactant mix as an additive for pickling degreasers for pickling solutions. It is suitable as additive for pickling degreasers for all solvents and is used as additive in salt, sulfur and phosphoric acid pickling bathes to reach a degreasing effect.The DELTA®-CLEAN ETCHANT 20 facilitates the removal of oxydes and oil carbon and leads to evenly pickled surfaces. With the help of the inhibitors you achieve a longer pickling time without a substantial attack of the surface. The hydrogen induced embrittlement of the base material is reduced with the DELTA®-CLEAN ETCHANT 20. It is the second step in the DELTA-PROZINC® cleaning process. DELTA®-CLEAN ETCHANT 20 is a highly inhibiting pickling cleaner additive and is particularly well suited for castings and heat-treated components (the base material is attacked only very slightly during cleaning). The use of this product promotes the removal of oxide and oil carbon. Only very little pickling bast is formed. Long service life.
