Cortec VpCI-M645 Inhibitor for Saltwater and Brines 5 GalM-645 is a newly developed corrosion inhibitor additive for corrosion induced by seawater or brine. M-645 is a highly surface active concentrate, which will displace water containing chlorides from the metal surface, is then adsorbed forming an oily protective film on the metal. This film is the most uniform when it is applied in conjunction with an oxygen scavenger. One of the biggest advantages of using M-645 as an additive to...
