Polyurea: General Overview with Specific Practical Applications

What is Polyurea?

Polyurea is being used successfully in a wide spectrum of applications today, and it is truly a remarkable technology for coatings, linings and joint sealant. For corrosion protection and abrasion resistance, Polyurea coatings and linings are more commonly applied over concrete and steel. Also for joint fill and caulk applications they have great advantages over conventional materials due to their fast set nature, high elongation and durability/abrasion characteristics. By spraying it into molds, Polyurea can be molded and shaped. In a similar way, Polyurea is also used for architectural molded fascia applications as a hard coat protective shell over expanded polystyrene (EPS).

New applications and market are continuously expanding. The opportunities for future, imaginative uses of Polyureas are unlimited. It’s important to understand that Polyurea itself is a description of a specific polymer technology, and is not a specific coating system or a specification. It is indeed a wonderful technology that can be realized in so many different formulations and physical property ranges. There are hybrid Polyurea systems and pure Polyureas, and each possesses its own specific characteristics, advantages and disadvantages.

Your protective coating or joint fill needs cannot be solved by Polyurea itself. It must be installed and specified in combination with correct surface preparation and primers, correct manufacturer's material formulation, proper equipment, quality control inspection and trained applicators.

Our purpose is to share quality, real-life Polyurea informations, successes, and conditions with you as a future user of our products and services to make your application a success. It is important to note that the proper combination of formulation, spray equipment, surface preparation, primers, training and application procedures must be taken into consideration by users and specifiers. This is what leads to Polyurea success.

Polyurea failure – and for that matter, failure of any protective coating and lining system – is the result of improper training, under-rated equipment and the lack of material or substrate compatibilities and preparation. It is important that for best results to always follow the system manufacturer's written guidelines.

Common uses for Polyurea protective coatings

• Waterproofing
• Corrosion protection
• Abrasion resistance
• Chemical, environment or atmospheric resistance
• Decoration
• Structural enhancement

These types of protective coating applications have for decades been performed with traditional materials such as paint, epoxy, fiberglass and vinyl esters.

Newer and more advanced than these traditional coating systems, Polyurea coating technology has been around for decades itself and offers many advantages to the owner, specifier and contractor.

The most important advantages are mainly due to the achievable physical properties, and its fast set, return to service characteristics.

Also, in a wide range of temperature and humidity environments it can also be applied over a variety of different substrates (concrete, metals, wood and more). It’s important to note, though, as with all protective coatings, Polyurea requires performing proper surface preparation and quality control testing during application.

The most important benefit of Polyurea is its fast set nature which greatly reduces facility downtime. Polyurea, compared to traditional coatings, can typically return an area to service many times faster, thus eliminating days and weeks of revenue-losing downtime as owners can more quickly put the facility back in use. Down time is key issue: it costs owners a great deal of money when facilities such as water tanks, waste-water clarifiers, parking garages and chemical storage tanks are taken out of service for maintenance and application of traditional coatings, which require vastly longer drying times.

Spray application is used in most Polyurea industrial uses which makes it fast to apply and accurate to proportion and mix. In one or multiple passes, this spray application style allows for virtually any mil thickness to be applied. In addition to this, with Polyurea, characteristics such as slip resistant additives and surface textures can be incorporated, UV stable colors can be achieved, and even KTW potable water approved systems are also possible.

When considering attainable physical properties, practically no coating can compare to Polyurea. Completely depending on how the material is formulated and applied, Polyureas can be formulated to achieve an enormous range of properties from high elongation to superior tensile strength to hard or soft.

Joint Sealants and Caulks with Polyurea

Polyurea is currently finding successful application as a multi-purpose joint fill, caulking and sealant material. This is because Polyurea can provide a durable, flexible, weather-tight and traffic resistant seal for all types of building joints, such as expansion joints and control joints in masonry floors, perimeter joints, panels and doors, water reservoirs, and others as well. Polyurea also has excellent crack-bridging properties with high elongation and tensile strength.

The quicker installation with a wider application window is due to the fast cure time and insensitivity to moisture. As usual, it is always necessary to have proper surface preparation and substrate condition.

The quicker installation with a wider application window is due to the fast cure time and insensitivity to moisture. As usual, it is always necessary to have proper surface preparation and substrate condition.

Surface Preparation for using Polyurea

It is quite possible to formulate Polyureas with some remarkable physical properties, including enhanced adhesion. But, it is important to note that nearly all successful Polyurea application involves proper surface preparation and testing, as will be shown below.

The use of primers is strongly recommended in most applications in addition to proper surface preparation procedures and techniques. For the best compatible system and primer combination for each particular substrate, you should always consult your material supplier.

Concrete Surface Preparation
First, concrete should cure for a minimum of 28 days at 21°C. But since hydration still continues even afterward, the longer you wait, the better. In order to assure that the concrete is fully cured, that adequate surface conditions exist and that proper system adhesion can be achieved, you should always test the moisture content and vapor transmission.

It is often required that concrete systems have vapor barriers or other means of waterproofing to prevent water intrusion, something which could ultimately lead to delamination and failure of the coating system itself. Furthermore, all grease compounds and other foreign matter on the surface needs to be removed either by sandblasting, shot blasting, mechanical scarification or suitable chemical means.

Any cracks found in the concrete need to be routed and filled with an appropriate material compatible to the primer system, and any bug holes need to be filled with the same material. Any sharp or rough surfaces should be ground to avoid protrusions. Finally, in order to aid in proper adhesion of the primer and Polyurea system, the concrete surface should also be prepared with a grip enhancing profile.

Steel Surface Preparation
It is important that steel surfaces are also free from any contaminants such as from rust, salts and dirt. Any welds need to be free of voids and spurs, and sharp protrusions should be ground down smooth. Prior to application of the primer and Polyurea system, be sure to test the surface conditions.

In order to create a surface finish for the Polyureas and primers to chemically and mechanically adhere to, the steel surface should be blasted to near white finish and left with a 50-100 μm profile.

Liquid containment railcars are commonly lined with Polyureas due to their waterproofing and chemical resistance benefits. The strength of Polyurea and its ability to resist abrasion has benefited hopper-style rail cars, which often carry coal, sand, and other abrasive materials. If applied properly, Polyurea will last longer than many other conventional systems and can be put on quickly.

Line Striping
Being a very fast set material, Polyurea is ideal for use in line striping and pavement marking. Depending on the formulation, road surfaces can be returned to service for traffic and pedestrian use in only a few minutes after application. Typically lasting much longer between maintenance cycles, Polyurea is much more durable than paint. Because of this, when it comes to cost and performance payback and operation, Polyurea is the ideal choice.

Spray Molding
With the development of low output spray guns, the use of Polyureas for spray in mold processes is gaining momentum. Polyureas are meter mixed and dispensed through plural component equipment and have very fast reaction times. Within seconds after application these materials are dry to the touch, thus dramatically reducing demold time. Physical properties of these materials can be modified by the system formulator with the purpose of meeting application requirements.

Bed Liners for Trucks
Truck bed liners made from Polyurea form a durable, water- and air-tight, permanent liner for the exterior of pickup trucks, dump trucks and steel containers in general. Utility trucks are protected from their harsh duty environments by these durable, easy to clean and abrasion-resistant liners. Trucks and containers are also protected by these liners against damage by rust and corrosion. With their ability to be applied in varied thicknesses, Polyurea liners can be used to meet any specific application demand. Available in many colors, sprayed-on truck bed liners can also be wrapped over the top edge of the truck bed to provide extra protection from impact and abrasion.

Facility owners are turning to Polyurea because it is spray applied, water resistant liner, available in a variety of colors with rapid return to service installation.

Landscape and Water Containment
Similar benefits with Polyurea have been found by landscape designers and contractors where Polyurea is often used to form a primary containment liner to contain water for ponds and pool decorations. When applying Polyurea over dirt, use of geotextile material is common. As usual, proper surface condition is vital when applying Polyurea over concrete and most other substrates.

Architectural Design
Uses for Polyurea are quite similar in architectural design as they are in theme park applications where Polyurea is often to form protective coatings over foam, EPS and other structures to create artificial rocks, pools and environments, ornamental building fascia, and themed characters. Polyurea is also successfully used in movie set and theater stage design.

Automotive Fascia OEM Molded Parts
Polyurea in its many uses can be spray, open pour or reaction injected into molds. Polyurea RIM systems have been used to mold many automotive fascia parts. And now many parts commonly made from fiberglass are being replaced by many spray mold uses. There are many uses for this molding system: water park chutes, plaques, architectural decorative molding, automotive aftermarket fasciae and spoilers, and many more are possible.

Playgrounds and Water Parks
Applications including molded slides, protective coating of seats for wet or dry amusement rides, tank linings, water containment, aquariums, and concrete stadium seats are just a few of the many possible applications where Polyureas are commonly used in the amusement and theme park industry.

Due to their fast cure and easier maintenance, the use of Polyureas is generally growing: they can replace paint and fiberglass in many areas of application.
