For a long time, epoxy, along with urethane, has been the standard in protective coating for industrial and commercial applications. Due to their excellent substrate protection, durability, and resistance to the elements, they lengthen the lifespan of metal and concrete surfaces.
Epoxy is also safe to be used and cured indoors. Also, as an added advantage, epoxy is resistant to most chemicals used in heavy industries. One example of this is sulfuric acid, for example, which is highly corrosive to metals.
In recent years, however, polyaspartic coating entered the fray and gave epoxy and urethane serious competition.
But since polyaspartic is still new, epoxy remains the standard in coatings. To illustrate, data showed that the market size for global epoxy was already $21.5 billion in 2015. The industry has a compound annual growth rate of 7.8% during the forecast period from 2016 and 2024. This means that the market could grow to $42.2 billion by 2024.
There is no data yet on polyaspartic coating, but it still has a long way to go to catch up to both epoxy and urethane.
What is Polyaspartic Coating?
The product is actually a hybrid innovation that shares similar characteristics to polyurethane. However, it has been modified to become a better option for both epoxy and urethane. For instance, you only need to apply one coating on the surface, and it will produce results similar to two coats of epoxy.
One criticism of polyaspartic coating was that it did not stick to the surface as much as epoxy does. It might be accurate, but only during the early iterations of the product. You would not encounter similar problems with modern brands.
Benefits of Polyaspartic Coating
One clear advantage is that you save on cost. Since you only apply one coat compared to two with epoxy, you get the most value for your money. The workers will finish earlier than usual, which is good news if you pay them by the hour.
Meanwhile, polyaspartic coating is also softer and more versatile since it offers higher resistance to chemicals and impact compared to epoxy. For instance, underwater pipes, which are exposed to intense pressure, will perform better when coated with polyaspartic paint.
Its anti-corrosive properties also make it the ideal option for automotive, construction and agricultural industries, heavy equipment, and power stations. But the high resistance to abrasion also makes it the perfect product to coat your restaurant, shopping mall, or hotel, where there is a high volume of foot traffic.
In terms of curing, the substance requires less time to do so. Manufacturers can do this by manipulating the esters that are present in polyurethanes. Since the chemical cures quickly, it causes minimal disruption to your operations. In fact, polyaspartic coating can also be calibrated to be applied on surfaces even at below-freezing temperatures.
Also, workers would be safer when they coat surfaces in confined environments. When you have poor ventilation, and they get exposed to chemical paint, it could pose serious risks to their health. However, polyaspartic coating emits low or zero volatile organic compounds, which would be ideal in tight spaces.
As you can see, polyaspartic coating is better compared to epoxy or urethane. Even if it is more expensive compared to both options, you get the most value for your money in the end.
