POLYUREA is a two-component polymer (Isocyanate and Polymer resin) with high molecular density, which after a brief exothermic reaction results as a very tough and very elastic coating.
A polyurea coating, a polyurea spray or a polyurea coating in general is nothing more than a resin. A polyurea coating generally consists of urethane foam that is thermoplastic. The resin component that goes into the foam is called a polyurea mixture. When the resin component reacts with the amine terminated in the amine group, the amine terminates in the hydroxyl group and the polymer component becomes hardened.
The main issue everyone must understand is that Polyurea by name is not a specific coating system or a specification, it is a description of a polymer TECHNOLOGY. A great technology that boasts so many different formulations and physical property ranges. There are pure polyureas (defined by the PDA) and there are hybrid polyurea systems, each possessing their own characteristics, advantages and disadvantages.
It also has a relatively higher flexibility index than other synthetic coatings. As a result, polyurea coatings have excellent physical characteristics, including water-resistance, and tensile strength, which makes it highly effective for use in aerospace and automotive waterproofing applications. Additionally, polyurea coating has a remarkable ability to attract and bind moisture, which provides exceptionally high water resistance. It is also resistant to ozone and UV, and hence suitable for use in a wide range of industrial coatings.
Because polyurea coating can withstand a large amount of force and because it provides exceptional physical properties, it is frequently used in structural waterproofing applications. Its high strength and toughness makes it ideal for reinforcing steel structure and flooring, and is often used in structures that are exposed to harsh weather conditions.
Advantages of Polyurea
The advantages of using polyurea over other types of coatings are many. The material has excellent moisture resistance and fast set time, making it suitable for a variety of applications, from roof top coatings to containment linings. Its lubrication properties make it an excellent choice for a variety of industries and applications. In addition, it has an extremely low evaporation rate, making it ideal for marine and coastal environments.
How is polyurea installed ?
Traditionally, polyurea is a two-part system, which is applied by spray equipment. Each part is shipped in 250kg drum sets. The parts are then transferred to separate tanks in the spray equipment. The machines combine the materials at precise ratios, and the resulting film is waterproof. The process takes about 5-15 seconds and requires no special tools or equipment. Once the layer has been formed, it is ready to use.
A polyurea is composed of two basic chemicals. A sulfate and an isocyanate. The isocyanate is the most commonly used in manufacturing and is an excellent choice for many industrial applications. Moreover, it is highly resistant to many chemicals, including hydrocarbons and hydrogen sulfide gas.
Polyurea coatings don’t need a certain ambient temperature in order to be applied. They can be applied in temperatures ranging from -30 to 140 degrees Fahrenheit, meaning you can apply it year-round and don’t need to wait for fine weather.
Uses for Polyurea
Despite its versatility, polyurea is not yet widely used in industry. It is not, however, suitable for all applications. Its physical properties make it a versatile material for a variety of applications. It is highly flammable, but is very resistant to water. Nonetheless, it is an environmentally friendly and versatile substance. This material can be used for everything from insulating insulation to linings in the construction industry.
Unlike other materials, polyurea is a versatile material. It is highly resistant to water and corrosion. Its quick-drying and flexible nature make it an ideal choice for a variety of applications, including roof top coatings and containment liners. It is also useful for car parking lots and other outdoor surfaces.
Polyurea is highly suited to exterior coatings. It has a high elongation and fast-curing rate, which make it ideal for coating steel and concrete. It also has excellent adhesion and abrasion resistance, which makes it an ideal choice for outdoor applications. It can be used on a variety of surfaces, from flooring to pedestrian decks. Even in the interior of buildings, polyurea is a durable coating that can be customized to suit the application.
Benefits of Polyurea
Polyurea has a range of benefits that will serve you well both immediately after install and for years to come.
Quick Installation
The first benefit of polyurea is that it’s fast to install. While epoxy can take 2-3 days to install, polyurea can be installed by professionals in a single day (or less!).
Polyurea is applied in two coats, the first containing the color and primer, with a second clear coat placed over top. Each layer dries rapidly, cutting installation time to a single day. This means that not only are you saving time and money on installation costs, but you won’t have to go without your garage for multiple days on end.
It’s important to have professional polyurea floor installers conduct your install to ensure it is applied properly to maintain its durability and strength.
Fast Drying
Epoxy coatings will take 24 hours to dry to a point where you are able to walk on the surface, and a full 7 days before you are able to drive a vehicle on it.
In contrast, you can walk on polyurea coatings within 8 hours of application and vehicles can drive on it after only 24 hours.
This makes it perfect for businesses who can’t afford large amounts of downtime, or residents who have no alternative space to store their garage items and vehicles.
In addition, polyurea’s fast dry time decreases the chance of bubbles forming on the surface, further ensuring you achieve a smooth clean look.
Polyurea will also only dry once professionally applied to your concrete surface. This means it won’t dry out or clump in the container, ensuring a perfectly even application every time.
Temperature
Polyurea coatings don’t need a certain ambient temperature in order to be applied. They can be applied in temperatures ranging from -30 to 140 degrees Fahrenheit, meaning you can apply it year-round and don’t need to wait for fine weather.
Once installed, polyurea can also withstand high temperatures. This means your floors will remain strong and intact even in hot climates, and you will not cause damage by exposing them to hot tires.
Virtually no odour
Polyurea is low in volatile organic compounds (VOCs), which are chemical gases that are emitted from certain products and have been linked to negative health effects.
The offensive odour of VOCs makes high VOC products less appealing, particularly when used in indoor spaces, such as garages.
Polyurea has virtually no odour during installation, or afterward, making it perfect for both residential and commercial uses.
Slip-Resistance
Garages are prime locations for possible slips and falls that can cause serious injury. Water and oil spills are commonplace in garages and can create a dangerous hazard. However, polyurea can eliminate this risk. After the topcoat has been applied, professionals can add slip resistance to the surface if you desire. For floors that may get wet or slippery, this addition is very worthwhile.
100% U.V stable
Polyurea floors will remain crystal clear during the application process, and once cured completely seal out moisture, ensuring they never yellow with time.
Durability
Polyurea floors are extremely durable and stand the test of time. You are guaranteed a strong, flexible floor that will withstand daily wear and tear. It won’t scratch and will be resistant to cracks, mold, chemicals, and stains, including salt.
Polyurea is highly flexible, making it absorb shock and impact without cracking. Its flexibility allows for the natural movement of ground and concrete, where other floors would crack, polyurea will flex with your floor, maintaining a smooth surface.
Polyurea is easy to wipe or mop clean, no scrubbing is required.
Budget-friendly
Polyurea pays for itself over time. As it only takes two coats to apply, it is a budget-friendly epoxy alternative. Furthermore, the short installation time keeps labor and installation costs low, and the incredible durability of polyurea means you won’t be spending money on maintenance or repairs in the future.
Classic look
Finally, polyurea provides a high gloss finish, giving your garage floor a sleek, elegant look.
