What is an MCU Coating?
MCU stands for Moisture Cured Urethane and makes a very superior high performance coating. These are a unique type of coating much better known in commercial industrial painting circles than within the general public market. Most MCU coatings use tiny aluminum flake as pigment which gives them their classic silvery/gray color and enhances their remarkable properties.
MCU contain lots of solvents which aids in penetrating tiny cracks and crevices. The coating scavenges moisture from its contact surfaces and the air and undergoes an cross-linking molecular process which 'grips' or grabs onto surfaces for outstanding adhesion, even with poorly prepared surfaces. Removing internal surface moisture removes one of the key components necessary for rust development.
The resulting dry surface (aided by the stacking aluminum pigment platelets) provides a physical barrier to air and oxygen, another necessary component for rust to form. The result is a thin, hard coating that seals our air, water, salts, minerals etc. essentially encapsulating the surface It therefore is one of the best, easy to apply, rust and corrosion control coatings.
Its amazing adhesion results in a versatile coating well suited for use on steel, aluminum, concrete, fiberglass, wood etc. It can be used as a primer/sealer, a middle coat or a exposed as a topcoat. The aluminum pigmented versions have no UV issues, can be applied at low temperatures and operate at temperatures of up to about 400 degrees F. Besides being used as a rust stopper is also has applications on boats, roofing and flooring applications. In is used a lot in the industrial, automotive, marine and farm marketplaces. The AUTO RESTORATION market is one place these coatings are widely promoted within the 'DIY home' marketplace.
One of the major differences with our Aluthane MCU and other aluminum MCU coatings is that we use 100% urethane resin and all (or just about everyone else) thins or dilutes their urethane resin so that the end product is less than 100% urethane resin and aluminum. The difference with these cost cutting/profit enhancing measures is a product that just doesn't perform or last as long as our pure resin system. Over time the differences are easy to observe and I have actual customers that have tried the competition, but then come back to our Aluthane MCU.

Better product and more than 1/3 cheaper AND
better coverage compared to "15" -- or "BULLET"
TESTING RESULTS: I coated an Armstrong brand commercial floor tile (12 inch by 12 inch), as well as a piece of plywood, with one coat of Aluthane and submerged it in a freshwater pond for 5 months. Both samples were perfectly intact (no peeling, blistering, softening, etc. at the end on the test. While urethanes are generally not considered suitable for immersion applications, this product appears to work fine underwater We cannot officially warranty it for immersion, but I personally now feel comfortable enough that I would use it on a dinghy boat bottom, boat mooring, submerged pump, etc.
More about our Aluthane product (5/05): from personal experience I can say that it makes a great primer (primer page), bonding solidly to surfaces that other coatings will not. I personally like it on wood (really soaks in!) such as porches etc. It can be painted over with latex or enamel without problem (or left alone). What's really nice is that when sanded lightly it gets darker in color, so when used as a primer/sealer, a bit of sanding will show high (dark) spots and low (lighter) spots as you sand smooth the surface.
I like using Aluthane under enamel or latex topcoats (not epoxies). It works better than a solvent thinned epoxy undercoat.

ALUTHANE - aluminum MCU (moisture cured urethane) super coating
Just wanted to let you know how well Aluthane works as a coating for a boat anchor. We have a 41 foot DeFever trawler with a 55# SuperMax anchor that dates to the late 1990s when they were first produced. Over the years and a lot of anchoring in various types of bottoms, the galvanized coating on the anchor had deteriorated to being almost non-existent and the underlying steel was starting to rust lightly. It's almost impossible around here (east coast of Florida) to get anything regalvanized, so looked for alternatives.
Aluthane jumped out at me as a good choice for a test. Before we
departed on our latest 4500 mile cruise from Florida to Maine and return, I "painted" the SuperMax with two coats of Aluthane after brushing off all the rust I could and coating it with Ospho prior to the application of Aluthane.
Five months, lots of rain and ocean spray, and 51 nights at anchor in various types of bottoms from sand and gravel and rock to mud, the Aluthane had worn off at only the very tips of the anchor (the area that digs into the bottom) and exposed the underlying steel. The vast majority of the surface area of the anchor was still being protected by the Aluthane.
I just finished adding two more coats and it looks great!

Good Afternoon Paul,
Just wanted to send a note that you should share with new customers about the ALUTHANE product that you recommended for a project I was bidding. I was approached about repainting the loading dock diamond plates at an overnight package service terminal. The original paint was only a little over three years old and the plates were very rusty and showing extensive wear. The customer would be an important add to my client base so I wanted to make them happy with our first shot. I originally contacted you about using an epoxy coating but you strongly suggested the Aluthane moisture-cure urethane as the best solution. You couldn’t have been more correct. After following all the necessary preparation steps, we applied two coats of the Aluthane to all the surfaces, including areas that we just couldn’t surface grind or effectively reach. We did power-wash and dry all the surfaces but that meant some spots may still have surface rust that would be painted over. To see the final results, you’d swear that we installed new plate material rather than repaint it. It is just that good! The stuff is bullet proof!
Thanks again for helping to make us look so good! -- Bill -- AXXB Construction Services, LLC 11/17

"Paul, just thought Id let you know, used Aluthane on bottom of a fiberglass/ epoxy hull repair, on my high speed powerboat tunnel cat. Left it on a mooring in Maine for about a total of 3 months (8 times for 3 week stretches) since last May. Paint is still perfect - submerged 3 weeks at a time." - Dave 10/16
(customer review) "Many aircraft paint systems use finely powdered aluminum as a blocker, and this is a proven technology. The paint must stick well to dacron, retain good flexibility for many years, and generally be a tough coating. It should seal the fabric, reducing any airflow (air leakage) to a minimum. In my experience Aluthane meets these requirements.
Aluthane wets out on dacron beautifully. It penetrates and seals, too. I made up a 18" x 20" test panel and stretched 2.7 oz aviation fabric at 300F.
I had Aluthane on a dacron outdoor test panel for five years. It was still in good condition after five years, and continued to adhere well. I flew an airplane for four years with the Aluthane topcoated with Polyfiber Bahama Blue. Both the Aluthane and the topcoat remained flexible.
Aluthane also appears to stick like crazy to both aluminum and fiberglass!" email - 10/14

Thanks Paul; here are a few comments on the Aluthane.
I was looking for a product to use on the 4" steel pilings on a newly constructed boat house. I wanted to extend the life of the piles and the overall structure since the boathouse cost roughly $50K to build. Aluthane was recommended. At the time, the water was down around three feet from normal pool so I was able to paint roughly 4 feet of the piling that was exposed. For prep, I used a simple paint scraper to smooth off the rough, loose rust and then a wire brush. I did not put a lot of effort into preparation. Total prep time per piling was no more than 3-5 minutes. I used a 3" roller and rolled the Aluthane on. Again, very simple and quick.
I was working on the boat today and couldn't help but notice how sharp my aluminum hardtop (still) looks after a very harsh summer of hard work on the salty ocean and a long New England winter exposed to the elements.
I remember the day I finished welding my hardtop and sat baffled as to how to finish it. You see, the hardtop frame was comprised of a half cut-up Mako tower (anodized aluminum) and scrap 6061 aluminum, all TIG welded together. With little to no prep, aside from a light sanding and a wash with alcohol, I was able to brush on (stippling) two coats of Aluthane in a day and have the boat launched a week later. Since then, the frame has seen rope chaffing, scrapes, climbing crew with abrasive sandy shoes, and harsh sun and seawater. The finish has never worn through and shows no signs of damage.
It has held up marvelously. So well in fact, I go out of my way to find things to paint with Aluthane. So far, I've painted my engines heat exchanger, primer my manifolds and risers, painted parts of my galvanized trailer including the wheels, and various mixed metal hardware on my boat.
I've recommended this product to others looking for a tough coating that can take a beating. A little goes a long way with Aluthane and it is almost funny how easily it goes on, rolled or brushed. One caveat, brushing will show brush marks so I usually stipple the surface with a brush with its bristles cut way back (or roll it on). Continuous mixing is key, too. It isn't glossy which is nice in some cases.
From comment section of 6/2010 online order for 1 gallon of Aluthane: "Returning (vendor note - a past customer). Spiral stairs near ocean. Wonderful coating that resists corrosion."
John (2/16/2012 email): A Wonderful Product!! Love Using It For A Little Of Everything!!! Proud To Buy American Products!!
My first experience w/ Aluthane was on my 1966 Starcraft boat....then with the left over quart I did the main door on my garage.....after that....I still had enough to apply a coat onto my rear bumper of my F250. This time around.... I used 1 quart again on: The in and outside panel of a retired U-Haul Truck (33 5/8 in. x 6 1/2 ft).....all the interior wall panels of the box truck (it's a 14 ft. box with grandmas attic)....and a 80# saddle propane tank. It's been an average of 28* up here for a high and it applied beautifully.....drying time is slower (I expected this)....but it coated just as smoothly as if it was 75* and sunny.
I totally agree.....b4 I crack a 1 quart container....I make sure I have enough things to coat so I don't hafta waste it in the garbage. I've been telling as many people as I can about Aluthane (and about you guys and galls).....telling them what I've been using it on and how nice it looks...and how smoothly it helped water proof my 46 year old boat and with a teeny bit of help from Marine Goop. My boat flows so smoothly through the water.....you would have never guessed that it leaked pretty good b4 the Aluthane and Goop.
I just hope and pray that this Economy and World Govt. doesn't shut you guys and gals down. That will be a VERY VERY SAD DAY for all the DIY's and commercial and industrial accounts you deal with on a regular basis.
Keep up the WONDERFUL WORK!!! Love the product so much!!! OMG.....I wanna coat everything exterior with it.... LOL. But seriously... when I get a chance.... I will be using the 1 Gallon Aluthane to do both of my porches. Have a great day and year. And blessed be us all.
