Are Superior

Non-Asbetos MIGHTYPLATE Roof Coatings are made from the finest and most expensive ingredients to give you the highest quality coatings available on today?s market. Most asphalt roof coatings contain asphalt, solvent, filler, suspension agent and a fiber. Lets take each component separetly and compare MIGHTYPLATE with the competition

The Asphalt

Most asphalt used in the roofing industry is regular air oxidized asphalt. The air oxidation process hardens the asphalt so that it will be suitable for roofing. However, this process also makes the asphalt more brittle. TRC?s asphalt is produced with a special patented process (patent number 289125) which uses a catalytst during the oxidation process. This catalyst hardens the asphalt without making it brittle. This makes the asphalt ductile for a longer period which helps prevent cracking.

The Solvent

Most asphalt roof coatings are cut back with standard petroleum distillate type solvents. These solvents are excellent in keeping the coating liquid for cold applied systems. Texas Refinery uses an additional solvent (patent number 4302370) which makes the fiber disperse or unclump in the mixing process. With the fiber being more dispersed, better bridging is obtained on the roof.

The Filler

Other asphalt roof coatings use Dolomite type fillers due to their low costs. However, this type of filler does not have a uniform particle size and course particles tend to separate in the drum, Since the filler has some function in reinforcing the coating on the roof, this separation can lead not only to a non-uniform product product, but may also affect the overall performance on the roof. MIGHTYPLATE Roof Coatings contain a fine, air floated clay as a filler. Better supension is obtained and, since the particles are smaller, more reinforcenent per total weight of filler is obtained.

The Supension Agent

Non-Asbestos roof coatings require some kind of supension agent (thickener) to help prevent the product from separating fillers and fibers to the bottom of the drum during storage.Although this component plays a minor role in the performance of the formula, it has been and can be the major cause for instability. Therefore, more of the attention iin research and development in non-asbestos coatings is focused on this one ingredient. The most commonly used supension agent is Attapulgite Clay. This clay has the advantage of being very low in cost. However, as much as 2% - 4% is required to give good suspension. A major disadvantage of the Attapulgite Clay is that the longer it is in the liquid the thicker the coatings get - - to the point that the coatings workability and sprayability is affected. This progressive thickening process is caused by the absorptivity of the clay in that it will continue absorbing or soaking up the oils and solvents in the coating. MIGHTYPLATE Roof Coatings utilize a much more expensive Bentonite Clay that is may times mor efficient than Attapulgite Clay. Much Less is needed in order to keep the ingredients suspended. Less clay means less absorption phenomena and a much more stable product.


The Fiber

One of the most important components of a cold applied roof coating is fiber. This is most apparent from the problems that have developed since the removal of asbestos from coatings to eliminate health risks. Most roof coating manufacturers have replaced asbestos with cellulose fibers because of their low costs and non-hazardous nature. A few have gone to chopped fiberglass. Other than aluminum based top-reflective coatings, very few companies use polyethelene or polypropylene fibers due to their expense. However, Texas Refinery Corp. uses synthetic polyethelene fibers because of the higher quality coatings they produce.

Studies conducted using our Atlas Arc Weather-Ometer at Texas Refinery Corp. showed our chemists that polyethelene fibered coatings are much less subject to blistering and cracking than cellulose fibered coatings. Also, microscopic examination shows that the fiber structure of polyethelene is very similar to asbestos.

Polythelene is stronger and more flexible than weak paper or brittle fiberglass. Also, polythelene is not subject to decay, will not wick moisture as cellulose will, nor is it harmful as fiberglass can be.

Quality Control

Each production batch of MIGHTYPLATE Roof Coating is tested by our Quality Control Laboratory in strict accordance with the specifications set by our Research and Development Group.Viscosity testing is performed to ensure that the material has excellent workability and sprayability. Sagging tests are performed to ensure that sagging characteristics are maintained. Accelerated storage stability tests are performed by holding the product at 150 degrees Farenheit for one week and by heated high speed centrifugation to ensure the product is void of separation. Accelerated weathering tests are routinely performed in our Atls Carbon Arc Weather-Ometer to ensure that our coatings continue to hold upyear after year without cracks, blisters and pinholes. These are only a few of the tests constantly run on each batch of product to ensure our product quality.

In addition to our daily quality control program, Underwriters Laboratories make routine inspections of our Quality Control, Plant Manufacturing Facilities and Test Records.

In Conclusion

The conclusion - - MIGHTYPLATE Roof Coatings contain the finest and most expensive ingredients in cold applied coatings. They perform the best over the longest period of time.
