For decades, traditional materials such as paint, epoxy, fiberglass and vinyl esters have all been used as various types of protective coatings, some with more success than others, but each with its own challenges. Polyurea coating technology is not new. In fact, it has been around and in use for almost three decades now. Polyurea is newer and more advanced than these traditional coating systems and offers many advantages to the owner, specifier and contractor.
These advantages come mainly in the form of achievable physical properties, and its fast-set, return-to-service characteristics. It can also be applied over a variety of different substrates (concrete, metals, wood and more) in a wide range of temperature and humidity environments. However, like all protective coatings, using polyurea is no excuse not to perform proper surface preparation and quality control testing during application.
Polyurea protective coatings in Michigan (MI) are commonly used for the following reasons:
Polyurea's most beneficial asset is its fast set nature. It can typically return an area to service many times faster than traditional coatings, allowing the owner to put the facility back in use without days and weeks of revenue losing down-time. Downtime for maintenance and coatings on water tanks, wastewater clarifiers, parking garages, and chemical storage tanks typically costs facility owners a great deal of money as these areas must be taken out of service while other coatings are applied and drying.
Most industrial use polyureas are spray applied, so it is fast to apply and accurately proportioned and mixed. This application style allows for virtually any mil thickness to be applied in one or multiple passes. Additional characteristics such as slip resistant additives and surface textures can also be incorporated, UV stable colors can be achieved, and even NSF potable water approved systems are also possible with polyurea.
Other coatings are practically incomparable to polyurea when it comes to attainable physical properties versus the time savings from its rapid return-to-service and gereral longevity. Polyureas can be formulated to achieve a tremendous range of properties -- from high elongation to superior tensile strength to hard or soft, all based on how the material is formulated and correctly applied.
