aluthane on a steel structure
COMMON APPLICATIONS: rust preventing coating on metal structures (including bridges and fences),, trailers, replacing failing galvanized surfaces, aluminum boat sealing and top coat, perfect on most outdoor surfaces, auto restoration, hot temperature applications, applying in cold conditions, concrete, wood, metal floors, primer on wood and fiberglass boat repair, popular with tear drop trailer builders
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.

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
"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. The Aluthane will run, so you do have to roll it on and smooth any runs with another quick roll over.
The results looked great. Basically a shiny aluminum look. When the lake came back up to pool, I kept watch for any signs of deterioration and saw none 12 months after application. The water went back down even further in the last few months, so I was able to inspect much closer and even apply the Aluthane further down the pilings. There was absolutely no rust through with 12-15 months of submersion.
The Aluthane surpassed all expectations and I now am in a wait and see mode on how long it will last before corrosion...no signs yet. I know its not advertised for submerged applications, but I can attest that it works very well for at a minimum of one year in fresh water applications. Excellent product that requires very little prep and seems to be very effective.
