Polyurea protective coatings are commonly used in Kentucky for the following reasons:
- Abrasion Resistance
- Corrosion Protection
- Chemical, Environment or Atmospheric Resistance
- Structural Enhancement
For decades, traditional materials such as paint, epoxy, fiberglass and vinyl esters have been used to perform these various types of protective coating applications. Polyurea coating technology, though being in use for almost three decades now, is more advanced than traditional coating systems. Polyurea offers many advantages to owners, specifiers and contractors in terms of its physical properties, namely its near-immediate curing time, which results in a quicker return to service for a given installation. Polyurea can also be applied over a variety of different substrates, such as concrete, metal and wood, and is similarly flexible in applications of varying temperature and humidity.
However, like all protective coatings, polyurea is no excuse for failing to perform proper surface preparation and quality control testing during the application process.
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 losing revenue during down-time. Down-time for maintenance and coatings on water tanks, waste-water 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-delivered, which not only improves application time, but also the accuracy of proportioning and mixing of base components. This application style allows for virtually any mil thickness to be applied in one or multiple passes. Additional characteristics such as slip-resistant additives, surface textures and UV stable colors can be incorporated. Even NSF potable water approved systems are also possible with polyurea.
Almost no coating can compare to polyurea when it comes to intrinsic 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 is formulated and correctly applied.
