Polyurea Advantages
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, polyurea is no excuse not to perform proper surface preparation and quality control testing during application.
Polyurea’s major benefit 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. Down time for maintenance and coatings on water tanks, wastewater clarifiers, parking garages and chemical storage tanks costs the facility owner a great deal of money since 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.
Almost no coating can compare to polyurea when it comes to attainable physical properties. 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 materials are formulated and correctly applied.
