Underwater curing coatings
Underwater curing coatings
(OP)
Can anyone give me some leads regarding underwater curing coatings? My application: clarifier operating in waste water treatment of a refinery uses FeCl3 as a flocculent to remove solids and selenium from water to be sent out of the refinery. Some HCl is also added to maintain a pH of 6.3. The clarifier operates at ambient temperature, atmospheric pressure. It was originally built with a coating and zinc anodes. The anodes have reached the end of their useful life and the coating is failing around the splash zone where anodes can't protect anyway. We can clear the tank to allow us to clean and recoat, but we will only have about 3 days to coat a 3700sq ft surface (70ft diameter) with rake arms, and shroud.

We may use up most of the 3 days trying to prepare the surface.

And I agree with rorschach. Also, you're going to get the old adage "Good. Fast. Cheap. You get to pick only two." for this project.
