Polyurea Coating – What It Is and How Your Project Can Benefit from It

Polyurea coating offers flexible heavy duty protection

In the US the polyurea coating market has been existing since the early 1990s, but the coating’s durability, flexibility, and versatility means that new applications for the polyurea resin are being found all the time. The coating is currently used across industries for waterproofing, corrosion protection, containment of water as well as chemical and toxic substances, flooring, and mechanical equipment, and the polyurea coating market is still growing. Polyurea coating is also flexible with substrates, and is applicable on concrete, metals, wood, plaster, plastics, and more.

In this article we will outline the science, advantages and uses of polyurea coating, as well as helping you find polyurea coating manufacturers and suppliers for your project in the US.

Breaking down polyurea coating and its advantages

A polyurea coating is the result of a reaction between an isocyanate and a resin blend, which forms a plastic- or rubber-like compound. The polyurea reaction results in an elastomer which can be used in similar ways to other technologies like polyurethane and epoxy, but the protection the polyurea resin provides combines the best aspects of both these coatings. Polyurea coating is used for everything from mining equipment and pipeline coating to playground fixtures, waterproof tank linings, asbestos encapsulation, and more. The polyurea advantages include:

  • 100% solids –With a 1:1 volume ratio, the need for extra coats is eliminated, and the lack of solvents means it is also VOC free and environmentally friendly.
  • High resistance – A polyurea coating provides chemical, abrasion, and UV resistance, as well as being able to withstand extreme temperature changes.
  • Waterproof and anti corrosive – Polyurea paint and coatings have moisture insensitivity/resistance. They have low permeability and are also resilient to water, providing corrosion protection.
  • Fast laid and fast return-to-service – A curing time of seconds or minutes means there is an almost immediate return-to-service time, and downtime is many times less than with another paint.
  • Strength & flexibility – Polyurea paint has a high polymeric elongation meaning that it will stretch as well as resist punctures and tears

Polyurea paint versus other coatings

There are many reasons to choose polyurea coating instead of more traditional coatings like epoxy. While other coatings have their own advantages, polyurea paint outperforms them in certain areas.

Polyurea vs Polyurethane:
Though these coatings are related (both isocyanate-based), they have many differences. When being applied polyurethane based coatings are sensitive to temperature and moisture, where polyurea paint is not. Polyurea coating is elastic and can stretch, but polyurethane cannot. It also has a higher tensile strength.

Polyurea vs Epoxy:
Epoxies are sensitive to temperature, humidity and moisture during application, with longer cure times than polyurea. Epoxy coatings are not flexible with the expansion of a substrate, and UV radiation will cause it to discolor, unlike polyurea meaning that it is the go-to coating for outdoors, instead of epoxy.

Polyurea vs Cementitious:
Unsurprisingly, cementitious coatings provide little give, and have far longer setting times than polyurea. All cementitious coatings have long setting and curing times.

In short, choose a polyurea coating when you require a very fast turnaround in application, as well as when the application environment is moisture-laden, humid, below freezing, or hot. Polyurea is also preferable when you need a coating that can flex with the expansion of a substrate (like polyurea on wood) or want a super hard-wearing level of abrasion resistance.

Polyurea application technology – hotspray and polyaspartic coatings

Polyurea coating is a rubber-like coating which is commonly sprayed onto a substrate, yet roll applications of polyurea paint are also possible.

“Hotspray” is another name for the polyurea spraying process, because polyurea is most effective when heated to 140-160°F. The polyurea reaction is immediate, and the coating begins to cure in seconds. So, in order to achieve the heat and speed requirements, the two components are pumped into a special spray gun through heated hoses. They mix within the gun chamber where the reaction begins, then are sprayed immediately onto the substrate. This ensures the best performance from the coating, and the strongest physical properties.  Polyurea application is a precision business, and should be applied by trained, professional polyurea coating contractors; you will find polyurea coatings suppliers, manufacturers and contractors at the end of this article!

As well as being suitable for application across many substrates, polyurea hotspray coating is suitable for application across a wide range of temperature and humidity environments. It can be applied in sub-zero temperatures, or on damp substrates without changing its effectiveness. It can also be applied at any thickness, in a single application.

Even though polyurea coating is almost predominantly applied with spray equipment, it is possible to modify the polyurea paint into a form which allows for roller and brush applications. This polyurea paint is calle polyaspartic polyurea, and it is common as a floor coating.

By investing in polyurea you are already saving money in the low downtime and return to service losses, the lifetime of the coating (up to 30 years warranty in some cases), and the speed of application, meaning fewer work hours for the applicators. Note the polyurea coating price regarding material is significantly more expensive than for example epoxy, and the application of polyurea paint is rather complex and should be left for professional polyurea applicators. Nevertheless polyurea coating for sale can be found, and it is available for consumers, amateur application is likely to lead into a coating failure.
