All you need to know about Poly-Urea
Poly-urea coating has some of the major benefits that make it stand out among most protective coatings. Of course like every other material, it has some special necessities for proper implementations. For thousands of years, many scientists have discovered different natural materials. It also invented several synthetic materials for spellbinding waterproof coatings.
In this article, we’ll examine some queries listed by global industries, regarding the poly-urea coating system.
What is poly-urea coating?
Poly-urea is precisely an elastic polymer substance that majorly extracts from a step-growth polymerization process. It involves a combination of isocyanate or synthetic resin reactive materials.
Regardless of the composition of isocyanate either aliphatic or aromatic, it can also lift up the reaction. You can always complete it literally within a snap as it takes only a few seconds. The necessity of technical equipment for mixing is the main element of this process. You can also hire trained staff to monitor and handle those special reactors and machines.
Various combinations of isocyanate and resin ratio can yield the perfect moisture resistance, setting time, color contrast, fire resistance features, and other diverse properties.
Many industries also used the desired hybrid poly-urea coating system. This system is produced with a mixture of polyurethane in specific proportions. Moreover, this coating offers certain physical features similar to poly-urea, maintaining affordability.
Industries have been utilizing poly-urea coating systems for over 25 years due to their diverse applications including sewer lining, water treatment plants, tank surfacing, manhole fixing, and lining molded parts.
Different industries apply the poly-urea through spray which not only ensures proper installation but also dries under 15 seconds with the standard formulation.
Important features Polyurea coating system
Professional staff performs unique installation techniques for polyurea with proper machines. There are many prominent features and benefits of polyurea in major areas of industries.
Ultra-fast curing & easily applicable
Many industries around the globe prefer Polyurea because it tends to dry quickly. It cured within some seconds which is approximately ten times faster than any typical protective coating. You can roam around freely within the surface and can achieve gel time letting heavy machinery pass. You can get back to your routine work very quickly with the help of polyurea, helping to maintain your schedule.
Exceptional chemical resistant properties
Polyurea has the repellant feature for several chemicals which you can achieve otherwise. It also has some high-end mechanical properties including tear strength, tensile force, cracks control feature, and abrasion resistance. You can not simply compare polyurea to any other coating in terms of attainable physical properties. Polyurea can resist any heavy load mechanically or even chemically.
Humid insensitivity
The best thing about polyurea is that humidity can not affect it in any way. Polyurea possesses hydrolytic stability. It lets any residual moisture and relative humidity have a slight or no effect on the elasticity or coating of the polyurea coating system. Not only that but it also has thermal stability which doesn’t let any type of weather have any impact on your coating.
Environment-friendly application
Many industrialists use polyurea due to its environmentally friendly application. You just need two major components for even coating including a high temperature and high-pressure spraying machine. You can layer up any detailed or complex architectural structure with any desired thickness without any visible effect.
The durability of polyurea coating
Many manufacturers have tested and certified polyurea as incomparable in terms of durability. It can last for almost three to four years depending on the density and sustainability of the flooring attached to it. Polyurea has a firm adhesive structure and elasticity which makes it more useful in the longer run. The different niches of industrialists make use of polyurea coating systems in different ways. Some use it in concrete on walls, pillars, others in metal like pipes or electric surfaces. While some use it in wood on floorings, furniture, etc. It’s easy applicability is what makes it ideal for most people.
How to remove polyurea coating
If you’re going to remove a thick and evenly applied Polyurea coating system, then it can turn out to be your biggest nightmare. You won’t get any help from regular methods of blasting for your removal process. The abrasive material such as garnet and coal can bounce off the coated surface. It also turns it into a stretchy substance due to its elasticity without any ray of removal.
Different service providers and contractors have concluded two major removal processes to avoid any issue. They made this decision after years of pondering testing out different methods. All these methods have the different quality level and different percentage of removal which are as follows:
Mechanical removal
The most common method used for the removal of elastic polyurea coating is through mechanical processes like grinding, chopping, and cutting. The service providers make use of physical and mechanical tools that rip the thick coating with flexibility. However, due to ripping the surface is also affected thus chipping is done so that you can apply the polyurea coating again, if necessary.
Ultra high-pressure water blasting
The second option for removal is ultra high-pressure water blasting. Many cleaning agencies use this method for deep cleaning of various surfaces and upholsteries. Keeping the technique similar, we’ll treat the polyurea coated surface through a UHP blast. You’ll see the formation of rust within metallic substances after a water blast. However, the service providers will clean it with rust removal substance with additional charges.
Why hire someone to install polyurea coating
This COVID-lockdown has made everyone a DIY freak. People usually think of performing everything on their own. Whether it is home renovating, pipeline installation, pool, or lawn deep cleaning. After reading this blog, if you’re planning to work on the polyurea coating as a DIY project, then you need to do some initial research. Taking from us, we’ll suggest you play smart. You should rely on the professional staff only.
It is possible that after the project your flooring can turn out just fine. Yet, it is also possible that you’ll waste your time and money on it. Not only that but you can get a poorly-applied polyurea coating. But even then, if you want to work then you need to level up your knowledge and skills. There are many factors which you need to consider. Be sure not to miss so that you will not encounter any damage, temperature, or moisture issues.
How to paint on polyurea coating
The significant factor that depends on the painting of polyurea coating the performance. If the service provider can rate adhesive percentage up to 80% then it is ready for painting. However, if the coating isn’t adhesive you won’t be able to stick anything on it and the whole thing will drip.
The service providers initially use an industrial degreaser for extracting oil and grease out of the surface. Next, they ensure the research of the necessity of the local environment and surfaces. You have to do it before choosing the type and quality of the process. The main purpose of surface preparation is to create a firm mechanical bond by spraying the product. You have to fix any disruption on the surface before applying the coat. Any cut having a depth of more than ⅛ inch can have a serious impact on your entire polyurea coating system.
There are three different drawbacks of polyurea spraying. The initial is over-spraying, then wind control and lastly the time you can give to the surface before letting any heavy machinery pass through it.
You have to select the correct product and apply it firmly when spraying polyurea coating with the help of manufacturers and owners yielding the perfect result. You need to consult with a certified and professional polyurea coating service provider. You should avoid these problems with plural component spray.
Conclusion
Polyurea coating is a logical and tested technique. It allows thick coating and fast curing. It has all the things necessary for an ideal protective adhesive. Many manufacturers, industrialists, and designers have declared the polyurea coating system as one of the most beneficial materials to have existed. You need to leave the application and installation process on the technicians and professionals for even layering.
However, if you’re opting for the process yourself then you can’t blame the material for any error in the formulation. The makers have suggested going for Nohr-S for DIY polyurea projects. Not only that but you also have some relevant knowledge on handling and applying the polyurea coating.
