applying polyurea coating to vehicle interior

Provide heavy duty protection with polyurea coating

Polyurea coating has been on the UK market since the 1980s, but its durability, flexibility, and versatility means that new applications for this coating are being found all the time. It is currently used across industries for waterproofing, corrosion protection, containment of water as well as chemical and toxic substances, flooring, and mechanical equipment, just to name a few. Polyurea coating is also flexible with substrates, and is applicable on concrete, metals, wood, plaster, plastics, and more.

A polyurea coating is the result of a reaction between an isocyanate and a resin blend, which forms a plastic- or rubber-like compound. This elastomer can be used in similar ways to other technologies like polyurethane and epoxy, but the protection it provides combines the best aspects of both these coatings. Polyurea is 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 and polyurea hotspray, as well as helping you find polyurea coating suppliers and manufacturers for your project in the UK.


Top 5 advantages of a polyurea coating

Polyurea is a coating of choice in commercial, industrial, marine, and residential applications because it has many advantages over its alternatives. The polyurea advantages include:

Applying polyurea coating as polyurea hotspray

Polyurea coating is fast to apply and fast to cure.

  1. 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.
  2. HIGH RESISTANCE: A polyurea coating provides chemical, abrasion, and UV resistance, as well as being able to withstand extreme temperature changes.
  3. WATERPROOF AND CORROSION PROTECTION: Polyurea coatings have moisture insensitivity/resistance. They have low permeability and are also resilient to water, providing corrosion protection.
  4. 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.
  5. FLEXIBILITY AND STRENGTH: Polyurea has a high polymeric elongation meaning that it will stretch as well as resist punctures and tears.

Polyurea hotspray technology – application techniques and equipment

“Hotspray” is another name for the polyurea spraying process, because polyurea is most effective when heated to 60-70°C. The reaction that creates a polyurea coating is immediate, and it 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 hotspray coating is a precision business, and should be applied by trained, professional contractors.

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.

How does polyurea coating compare to other coatings like epoxy?

Why would you choose polyurea coating instead of a more traditional coating like epoxy? While other coatings have their own benefits, polyurea outperforms them in certain areas.

Polyurea coating can be applied on site or at manufacture by polyurea coating suppliers

The polyurea hotspray process can be by hand or automated – some companies even use robots.

  • 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.
  • 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 discolour, unlike polyurea.
  • 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 turn around 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, or want a super hard-wearing level of abrasion resistance.


Where to find polyurea coating suppliers, specialists and prices in the UK

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. There are many polyurea coating suppliers and other specialists operating in the UK.
