Protect your assets in harsh environments with polyurea coating
Polyurea coating has been on the market in the UAE already for 30 years and its durability, flexibility, and versatility allow new applications to be found all the time. Polyurea coating is currently used across industries for waterproofing, corrosion protection, water containment as well as containment of chemical and toxic substances, flooring, and mechanical tools, just to name few. Polyurea coating is also flexible when it comes to suitable substrates; it is applicable on concrete, metals, wood, plaster, plastics, and many more substrates.
Polyurea coatings result from a reaction between isocyanates and a resin blends, which forms a plastic- or rubber-like compound. These elastomers can be used in similar ways to other plural component coating technologies such as polyurethane and epoxy, but the protection it provides combines the best aspects of both these coatings. The polymer chains are longer in polyurea, meaning the coating has greater elongation. Polyurea spray coatings are used for everything from mining equipment and pipeline coating to playground fixtures, waterproof tank linings, asbestos encapsulation, and more.
In this article we will outline the benefits and uses of polyurea coating, as well as help you find polyurea coating suppliers and manufacturers for your project in the Emirates.
The top 5 benefits of polyurea
Polyurea is a coating of choice for commercial, industrial, marine, and residential applications because it has many advantages over its alternatives. The alternatives also have some of these advantages but polyurea has them all in one coating. The benefits of polyurea include:
- 100% solids: With a 1:1 volume ratio, the need for extra coats is eliminated, and the lack of solvents means it also VOC free and environmentally friendly.
- Strength and flexibility: Polyurea has a high polymeric elongation meaning that it stretches as well as resists punctures and tears.
- Waterproof and corrosion protection: Polyurea coatings have moisture insensitivity/resistance. They have low permeability and are also resilient to water, providing corrosion protection. A polyurea waterproof coating is also used as tank linings.
- High resistance: A polyurea coating provides chemical, abrasion, and UV resistance, as well as being able to withstand extreme temperature changes.
- Fast set 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.
Polyurea coating compared to other coatings
Why should you choose polyurea coating instead of a more traditional coating like polyurethane? While other coatings have their own benefits, polyurea outperforms them in certain areas.
- Polyurea vs Cementitious:
Unsurprisingly, cementitious coatings provide little give, and have far longer setting times than polyurea paint. All cementitious coatings have long setting and curing times.
- 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. However, epoxy coatings are more impact resistant than polyurea.
- 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 is not. Polyurea is elastic and can stretch, but polyurethane cannot. It also has a higher tensile strength.
Based on these polyurea advantages, choose a polyurea coating when downtime is to be avoided or minimised, as well as when the application environment is moisture-laden, or involves temperature extremes. Polyurea is also preferable when you need a coating that can flex with the expansion of a substrate, or want an extremely hard-wearing layer of with abrasion resistance.
High elastic polyurea spray coating and other possibilities
“Hotspray” is another name for this polyurea spraying process, because polyurea coating is most effective when heated to 60-70°C and applied with a spray gun. The reaction that creates a polyurea coating is immediate, and it starts 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. The components mix within the gun chamber where the reaction starts, the mixture then is sprayed immediately onto the substrate. This ensures the best performance from the polyurea spray, and the strongest physical properties. Polyurea hotspray coating is a precision business, and should be applied by trained, professional applicators. If you are interested in spray polyurea coating, Africa and the Middle East has you covered, with many professional contractors.
Sometimes a hotspray application is not convenient, but you still need a tough, waterproof coating with wear resistance. Polyurea coatings can be modified to change its behavior when applied. These modified polyurea coatings are better known as aliphatic polyurea or polyaspartic coatings. They are common as floor coatings due to their flexibility and fast application compared to epoxies and urethanes.
