Hello, an excellent quick drying product is Gulf Coast Paint- MCU100. https://gulfcoastpaint.com/mcu-100-primerfinish-moisture-cured-urethane-aluminum-coating
We use this on structural steel in our facility. Can apply 2 coats with 3 hours. Very fast drying and designed for industrial area.

Anything that exceeds 500 PSI on the ASTM D4541 test is what you want. That's a standard for most of the High Performance Epoxies on the market: SW Macropoxy 636, Devoe 235, Gulf Coast Paint's CM-15, Rustoleum 9100.
Here's an option we used in the past for tank internal tank lining: https://gulfcoastpaint.com/pc-517-poly-chemcure-high-build-glass-filled-epoxy-mastic/
I would contact the manufacturer and ask if the product can handle NaOH 40%.
Thanks,

Hi All,
Just curious as to where lots of you go to get your paints & coatings?
Online? ARCAT, Construction Connect?
Or do you have corporate specifications?
What are some other options you use?
Thanks,
Andy
Hi Simone,
Steve is correct. I would recommend an acrylic aliphatic polyisocyante. Acrylics have excellent UV & Gloss retention. 2 urethanes our facility uses is Rustoleum 9800 & Gulf Coast Paint CT-398. Both products have over 3500 hours in the QUV which shows the weathering effect on...
I would use an Epoxy Mastic Coating. CM-15 Epoxy Mastic from Gulf Coast Paint is a good product we've used in our facility. Self priming, great for immersion.
Acrylic's don't have very chemical resistance. You are also correct about epoxy durability. There's a company in Portland, OR called Technical Coatings Int'l that has a very good epoxy line and sealant caulking that might be good for this application.

Here's a potential as a fix that will hold you over. I've used this over tight rust before on steel beams and it worked great.

I've done work with Internal Tank Linings, floating roofs, etc and here's what I used when I worked at Chevron in Pascagoula, MS.

Gulf Coast Paint PC-517 Cycloaliphatic Epoxy
I would not use a polyurethane in this situation. I would recommend a Cyclo-Aliphatic Epoxy. They're designed for immersion in these situations. Polyurethanes are generally used for UV protection, gloss retention, etc.
We use a Moisture Cured Urethane in our facility over rusty surfaces. It's the best I've seen at sealing it, but it doesn't last forever. All we do is knock off mill scale and apply coating to tight rust. We use Gulf Coast Paint MCU-100 Aluminum...
I think something like a Cyclo-Aliphatic Epoxy would work good. I've used one in the past for chemical resistance and for immersion.
Here's the on I used. Gulf Coast Paint's PC-517

Does anyone have Paints % Coatings shows they like to attend? Corporate feels like we needs to get out and see some "new technology" and I wanted to get some ideas from you guys on what's out there.
