Pre-Treatment

Passivation Treatment (AFCO 2332) is a neutral, moderately low foaming, cationic surfactant which is designed specifically for the removal of electro-statically bonded micronic polishing dust from new stainless-steel equipment prior to passivation. The preferred method of application for AFCO 2332 is manual brushing, but in situations where manual brushing is not possible, AFCO 2332 can be circulated through a system. Because it produces a weak, unstable foam a defoamer like Super Defoamer (AFCO 1072) can be added to AFCO 2332 use solutions to reduce foaming for CIP cleaning.
