Polyurethane is an incredible compound that is used in many ways that some people might not know. Polyurethane comes from compounds termed ‘polymers’, which were created in the nineteen thirties. Polyurethane is considered to be one of the best multipurpose polymers in the industry. It is not only used for coatings, but is also used in apparel, appliances, automotive, construction, composite wood, electronics, flooring, furnishings, marine, medical and packaging. As you can see, it has quite an impressive resume!
Four categories can be created from Polyurethanes. They include coatings, cross-linked, flexible foams and elastomers. Each of the Polyurethanes has a unique job that it has to do. Here, we’re going to dive into Polyurethane coatings.
Uses for Polyurethane Coating
When it comes to Polyurethane’s use for coating, its full range of application is impressive.
These applications include:
There are numerous types of floors that Polyurethane can be applied to. Industrial flooring and commercial complexes are the most common. It is utilized in bowling alleys to give the bowling lanes that unique shine and luster. Polyurethane is also in aircraft hangers and body shops due to its durability.
This class of Polyurethane is aerospace grade and has been used by the United States Navy and Marine Corps, as well as many other companies and manufacturers. Not only does it help with protecting the aircraft, it also helps provide fuel efficiency. Though we see Polyurethane foams more predominantly in aerospace applications, polyurethane coatings are utilized as well.
It can help to protect valuable equipment from the harsh industrial environment. It also improves efficiency, by keeping the machinery working longer.
Polyurethane is used to seal marine hulls from corrosion, coastal elements, and harsh weather. It is applied to all categories of boats and ships, of various sizes and uses. Most interestingly, it’s used to secure and seal diving equipment.
This durable covering is used to protect gas and oil pipelines. Many are underwater, and since it can withstand the high pressure and harsh environment, it’s the perfect choice. It can also be used on other categories of piping.
Polyurethane can give roofing a longer lifespan than an acrylic base product. Extending the lifespan of an industrial roof can save the business on costly repairs. For this reason, it’s a wonderful choice for any project manager looking to save on their bottom line.
Coatings are used on the blades and bases of wind turbines. Polyurethane is a commonly used coating for these projects, since they can increase their energy efficiency in addition to protecting the machinery.
This coating is used in many places in our lives. It has many positive uses. Of course, there are some drawbacks to using Polyurethane coatings.
Disadvantages of Polyurethane Coating
Some of the drawbacks to using PU Coatings are:
- Exposure – If it is exposed to direct sunlight for an extended period, it can weaken its strength.
- Health Difficulties – The fumes that are emitted from applying the coating can cause problems with the lungs, eyes and skin. The fumes can also trigger allergic reactions, making it hard to work around.
- Odor – This disadvantage is tied together with the previous one. When working with this covering, you will need to take care to use protective gear to help lessen the effects. Proper safety measures are important in any industrial or commercial project.
If you are considering Polyurethane for your next project, you should seek the knowledge of a qualified company that has extensive experience with this coating. There is specific guidelines for surface preparation and cleanup that should not be attempted by novices.
