    Contego Reactive Fire Barrier Protects Ain Dubai Passenger Pods

    Dubai Eye steel pods coated with Contego Reactive Fire BarrierContego Reactive Fire Barrier Intumescent paint has been chosen to protect the frame structures of the 48 elegant passenger capsules incorporated into the worlds largest and tallest observation wheel the Ain Dubai (Dubai Eye in English).
    The passenger “pods” were designed and built by Molinari Rail of Switzerland. The steel and aluminum structures of the 48 capsules will be prepared, primed, coated with Contego High Solids Reactive Fire Barrier (RFB) then top coated. The Contego RFB application process will be handled by S.C. Omega Solutions Center S.R.L.
    The Ain Dubai will be the world’s largest giant ferris wheel. It is located on the $1.6 billion dollar Bluewaters Island development, off the coast of Dubai’s Jumeirah Beach Residence, with a projected 2018 completion date. The 48 luxury capsule “pods” of the wheel will be capable of holding 1,400 visitors at any given time and offer views of Dubai’s iconic landmarks.
    Over 210 meters tall, the Ain Dubai, will eclipse the 167-meter High Roller in Las Vegas and the 190-meter (625ft) New York Wheel to be built on Staten Island. The final structure of the Ain Dubai will include around 9,000 tons of steel, almost 25 percent more than the amount of iron used to construct the iconic Eiffel Tower.
    Two of the world’s largest cranes, each with a 180-meter-long boom (590 ft) and the capability to lift more than 3,000 tons are used to raise this remarkable structure. For reference, that’s a lifting capacity of close to 11 Airbus A380s. The assembled hub and spindle stretch 40 meters (130ft) across and 20 meters (65ft) high, weighing a total of 1,805 tons.
    Speaking of the Ain Dubai, Omar Delawar, Chief Projects Officer at Meraas, said: “Once completed, Ain Dubai will emerge as an engineering masterpiece, the first of its kind in the industry.”
    Abdulla Al Habbai, group chairman at Meraas, said: “Ain Dubai reflects our ambition of creating new destinations that contribute to His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of UAE and Ruler of Dubai, vision of a city where people are encouraged to create, explore and enjoy.”

  • Exciting News (This is a truly revolutionary intumescent deck assembly)

    Contego’s New D603 Floor Ceiling Assembly from UL Finally Puts An End to The Cementitious Nightmare for Fireproofing Decks

    Ugly cementitious fireproofing would be better with intumescent deck assembly

    Gone are the days of horrifically ugly sprayed on “oatmeal” that delaminates.

    Contego has been famous for cutting-edge super thin film intumescent technology – and now has a UL intumescent deck assembly for corrugate pan decking that exceeds two hours! Contego is thin, light, smooth, green and affordable as well.

    As Mel Martin, in charge of Contego’s Canadian Business Development, says “It’s not a question of if it [cementitious fireproofing] will fall off, but when.”

    Contego’s adhesion of 631 PSI, according to our ASTM D4541 test, is twice that of our one closest competitor and between ten and fifteen times better than most of the rest.

    Structural steel is protected with Contego’s thin film intumescent coating. You can see below the pervasive damage that spray-on fireproofing typically inflicts on steel.

    spray on cementitious fireproofing pervasive damage

    Here’s a shot of the two types of fireproofing side by side on steel beams.

    Of course, beams and columns also benefit from a thin film intumescent, but more on that in another post.

    For now, would you prefer this:

    Steel rotting under cementitious

    All of that brown discoloration is the steel rotting away under the cementitious product.

    Or would you prefer this:

    Contego fire resistant paint goes on smooth

    Historically, there were no options beyond cementitious. SFRM (Spray-Applied Fire Resistive Material) was the only way to get a rating on deck systems. No more. In the past, the only other reason to continue using SFRMs was because they were perceived as being cheap. Now people are finding severe damage to their structures where SFRMs have been applied. Some damage so bad that the building can’t be spared and people are realizing a lower initial cost is a terrible bargain just a few short years down the road.

    With the medical community also warning against the use of SFRMs, the potential legal liabilities make SFRMs the last thing you should use.

    Now all of that has changed. For those who like UL, our new D603 intumescent deck assembly clears the way to an astonishingly thin and smooth coating that can be top coated to unleash a world of creative options.

    Just as important, after reviewing the raw data, the Contego intumescent deck assembly was nowhere near failure at 2 hours, so the real rating is well beyond that mark. In the near future, we will run the same test extended to three or four hours as well as a very thin coat that is consistent with our ASTM-E119, UL-263,ULc-S101 test done at Intertek in 2009.

    Most of Contego’s data on steel can be viewed here on our Steel Fire Test page.

    Additional UL data can be viewed on UL’s website here.

    why you do not want to use cementitious fireproofing.

  • Contego Fire Barrier Scores Exceptional Test Results on UL-1715

    We are excited to share perhaps the most exceptional set of test results ever announced regarding any intumescent fire barrier and its ability to protect spray polyurethane foam insulation (SPF).


    SPF is unmatched as an insulation product, as well as an excellent sound and moisture barrier.  It must be protected from fire, though, in any situation where the space is being occupied or used as storage.  There are a few ways to protect spray polyurethane foam insulation, but nothing matches Contego’s reactive intumescent fire barrier coating. Contego is thin, beautiful, completely non-toxic and easily applied.
    Until Contego, test results were limited to a maximum of 15 minutes, which qualified it as a “thermal barrier”.  (There is a lesser rating for unoccupied space called an “ignition barrier”, but there are several products that can do this, so that is of little interest to us.)
    Now all of that has changed. You can check out a live burn of spray polyurethane foam in the video below (2nd half):

    Even though a few spray foam products are marketed as being fireproof, you can see that they are not. However, with two coats of Contego’s intumescent fire barrier, SPF is protected well above and beyond code requirements. Even repeated burns can’t get to the foam when coated with Contego.
    Here’s the exciting part. Note that all metrics were flat by 6:00.00 and remained so until the end of the test. Had the test been able to run for multiple hours, it is only logical to assume it would have performed no differently than it did at 6:00.00. This is further supported by our EN-13823 test outcome, which you can view (here-part 1 and here-part 2), that also flat lined in under six minutes and stayed flat for an additional 20 minutes before the test was terminated. Is one hour now possible? How about two? Frankly, it would have been able to go all day.

  • 9/11 and Why Adhesion Matters with Fire Retardant Paint

    delamination of paint  coating

    The delamination on this example shows that poor application can cause failure of adhesion just as an explosion can.

    Utilizing fire retardant paint for your fireproofing needs is more than just adhering to building guidelines — it can mean life or death. The tragedy of 9/11 made the case for that point forever.

    “If the steel in the World Trade Center could have been adequately protected for just a little longer, it might not have fallen,” says Tony Scott, Contego executive vice president.

    As flames engulfed the Twin Towers, the steel was exposed to temperatures of more than 2,000 degrees Fahrenheit, hotter than a normal cellulosic fire because of the jet fuel.

    However, an even bigger problem was the total failure in adhesion. The impact completely stripped the substrates of their protective coating.

    When heated to 1,000°F, steel loses half its strength: For instance, a beam supporting 2,000 tons could only support half that weight at 1,000°F, putting the entire structure at risk. “The World Trade Center collapsed because it could no longer support itself,” says Scott, “The weight of the floors above the failure acted like a pile driver collapsing the floor below. The increasing momentum guaranteed the total destruction of the Towers.”

    Contego thin film acrylic copolymer latex protects against fire

    By making sure you’ve used an intumescent product with excellent adhesion, you’ll keep structural steel (or any underlying substrate) cool and intact during a fire.

    Fire retardant paint keeps steel from reaching dangerous temperatures by insulating the substrate, even in extreme conditions. As flames heat the steel, the substrate loses shape. But fire retardant paint with strong adhesion allows the coating to continue to stick to the steel without flaking off.

    While the fire might be burning at 2,000 degrees Fahrenheit, the coating keeps the steel at a safe temperature for as long as possible.

    Fire-resistant coatings can’t withstand heat indefinitely, but the aim is to protect the steel long enough so the fire burns out or help arrives.

    Furnace fire tests and control burns show that Contego protects steel “extremely well for up to three hours restrained,” says Scott.

    What’s the Best Way to Test Intumescent Coating Adhesion?

    Adhesion of intumescent coatings is vitally important

    A paramount part of building design and planning, fireproofing improves building safety and longevity. Applied like paint, fire retardant intumescent coatings offer a relatively new option to protect your project. These materials shield steel and other substrates from dangerous flames, while standing up to other elements like weather.


    But how can you tell which intumescent coating offers the best protection? A critical, but commonly overlooked measurement of an intumescent coating’s fire protection is its adhesion — or how well it sticks to a substrate — and its cohesion — or strength of the coating itself.

    There are two ways to evaluate the adhesion and cohesion of paint: the tape test and pull-off adhesion test.

    For the tape test, (ASTM D3359) cross or ribbon cuts are made into a coated surface, and a special tape is used to pull off the paint.

    Your intumescent coating will peel if the adhesion isn't good

    During the pull-off adhesion test, (ASTM D4541) which is the industry’s more definitive test, this is what occurs:

    • A steel plug, called a dolly, is placed on the coated surface.

    • A large amount of pressure is then applied to pull up the plug and the coating.

    • Testers then determine if the failure was adhesive or cohesive.

    • The amount of pull, measured in pounds per square inch, is increased until the bond eventually fails.

    • The higher the number, be better the bond.

    “Ideally what you want to see is an adhesive failure because that means you’re getting the maximum strength out of the intumescent coating, and the failure is not within the coating, but rather at the substrate,” explains Tony Scott, Contego International executive vice president.  In both tests, Contego received a perfect score — zero loss or 100 percent adhesion on both the cross cut and ribbon cut variants of ASTM-D3359. “You can’t get better than that,” says Scott. On the ASTM D4541, Contego showed 631 psi of bond strength. The closest competitor demonstrated half the adhesion Contego has, while most had one-third to one-fifteenth of Contego’s strength.

    Contego Intumescent Coating Adheres tightly to concrete core sample

    Contego adhered tightly to cut concrete core sample.

    Fred Stack, president of Boss Construction Group, recently joined Lindsay Construction to test Contego products on a 6-inch concrete core sample. “It was amazing how Contego still adhered to all surfaces, even after the concrete was cut out,” says Stack. The core sample “looked like it was just sprayed,” adding that officials at Lindsay Construction “were very impressed.”

     In a fire, the superior adhesion in Contego’s intumescent acrylic copolymer latex paint keeps steel and other substrates from reaching failure or flashover temperatures.
