Polyurea Companies and Polyurea Coatings
The effect of polyurea coating on blast resistance of steel plates is studied in AOE 5315 Naval Ship Vulnerability and Underwater Explosion course taught at Virginia Tech. In this article, authors M. R. Amini and S. Nemat-Nasser present their results in Proceedings of the 2006 SEM Annual Conference and Exposition on Experimental and Applied Mechanics, held in St. Louis, Missouri.
The growth of the polyurea coating market is driven by the increasing popularity of the product in the construction industry. It is used in new and old construction, and has many applications. The largest markets for polyurea coatings are North America and the Asia Pacific, which present large opportunities for players in the industry. The construction industry in these regions is experiencing rapid growth, due to the increased per capita income and urbanization of developing economies. The application spectrum of polyurea coatings is broad and diverse, with applications in steel manufacturing, automobiles, and protective applications.
The durability of polyurea coatings depends on how the concrete surfaces are prepared. If the concrete surface is not level and uneven, the coating will not adhere properly. A good installer should have industrial-grade equipment and tools for the job. This can help ensure that the coating lasts a long time. The installer should also have the experience to perform a professional job. Ultimately, the polyurea coating should last for many years.
The spraying technology segment is expected to dominate the polyurea coating market in the near future. This technology involves pumping components such as isocyanates and resin blend through a storage drum into a spraying machine. These components are then sprayed onto the surface in a 1:1 ratio. The spraying machine must be designed in such a way that it can keep the pressure and temperature range. Moreover, the machine must have precise control and dosing of the ingredients to ensure the best results.
Besides being fast and easy to install, polyurea also offers superior protection over other coating materials. The concrete clarifier had extensive cracks, and Osborn decided to apply a polyurea coating for its superior protection. Cracks over 0.125 inches were repaired with concrete repair grout. The walls and floor were primed with primer before the polyurea coating was applied. Osborn completed the project on time with a ribbon-cutting ceremony.
Polyurea systems are generally more expensive than other coating systems, but can be applied to areas that other systems cannot. Regardless of the cost, polyurea systems are the better solution when considering processing time and waiting period. However, the initial investment is high, and the quality of the service is highly dependent on the applicator and equipment used. With such high costs, hiring a skilled operator is a must for the best results.
Polyurea coatings also improve corrosion resistance and enhance longevity in containment tanks. These coatings protect against the effects of extreme temperatures, corrosion, and everyday wear and tear. Polyurea coatings are ideal for the oil and gas industry, because they can be applied quickly. They can also protect the primary containment systems from a variety of hazards. There are various applications for polyurea coatings in the industry, from protecting wastewater containment systems to manholes.
