Spray Polyurea Markets and Applications
With a range of uses limited only by your imagination, Polyurea is a truly remarkable technology. As with any coating system, though, it is necessary to ensure proper surface preparation, the use of correct application equipment and compatible primers. In the following paragraphs you can find out where and how Polyureas are successfully being used around the world.
Coatings and Linings for Pipes and Pipelines
Increasing use is being made of Polyurea coatings and linings to protect steel pipes from corrosion. Polyurea has demonstrated its ability to last longer than paint, leading to reduced maintenance services and costs. For pipes that are insulated with polyurethane foam, Polyurea is a great protective coating system. Also, for infrastructure rehabilitation work, Polyureas are also being used to line the inside of water and sewer pipes.
Coatings on Bridges
Polyurea has the ability to outlast paint and fight off corrosion, and this is an important reason why these systems are being used in specifications for bridge decks and structure coatings by Ministries and Departments of Transportation around the world. Coatings over steel and concrete are the most common applications of Polyurea coatings on bridges.
Joint Fill / Caulk
Polyurea is successfully applied as a multi-purpose joint fill, caulking and sealant material, as it can provide a durable, flexible, weather-tight and traffic resistant seal for all types of building, and also has excellent crack-bridging properties with high elongation and tensile strength. It offers quicker installation and a wider application window, due to the fast cure time and insensitivity to moisture. As usual, it is always necessary to have proper surface preparation and substrate condition.
Steel tanks can be protected from corrosion, chemicals, and other natural weather and jobsite elements with Polyurea coatings. Polyurea goes on fast and stays on long with proper surface preparation, substrate condition, formulation choice, primers, and installation procedures. The life of older tanks can be extended with Polyureas and it and can offer limited structural characteristics, too. Application of these systems can be done during primary construction or in a retrofit environment. Polyureas have fast cures times and so they are ideal for retrofits since down time is significantly minimized compared to some competing materials.
Fuel Storage and Containment
Polyurea is commonly used in fuel pits and pipeline secondary containment since it is resistant to many fuels and chemicals. But, the necessary compatibility tests and surface preparation are always required since Polyurea is not resistant to all chemicals.
Polyurea Blast Mitigation
When used as a wall coating for bomb blast protection, Polyurea used in a composite system with other materials has proven itself to be extremely durable and resilient.
Racecar body parts
Polyureas are ideal for new storage tank primary lining and also rehabilitation projects because of their fast application advantages and ability to adhere to properly prepared substrates. Polyurea linings are resistant to many industrial liquids and chemicals.
Polyurea can be very effective in protecting steel, aluminum, and fiberglass in a variety of water sport and commercial marine applications both above and below the water line. Polyureas are used in many abrasion, chemical and corrosion resistant marine applications from sound attenuation for fishing canoes, to fish hold liners, to hull protection and bilge liners.
Coatings for Roofs
An excellent protective covering for polyurethane foam roofs, Polyurea coatings can be formulated to meet specific performance requirements due the wide range of physical properties that can be configured. Some Polyurea coating systems have reflective and color stable properties. The energy consumption of buildings for heating and cooling can be reduced through the use of these reflective coatings. Also, they provide quicker installation with a wider application window due to their fast cure time and insensitivity to moisture. As usual, proper surface preparation and substrate condition is always a requirement.
Linings for Waste Water Treatment
Polyurea concrete primary and secondary containment linings are fast cure, and chemical and abrasion resistant. These qualities make Polyurea applications ideal for the wastewater treatment industry.
Linings for Manholes and Sewers
Polyurea's ability to solve many current problems with groundwater infiltration and installation speed have made Polyurea manhole lining a rapidly growing market. There is a great need for lining and structural repair of many municipal and private water systems. Polyurea and primers with proper surface preparation and substrate conditions can be applied quickly to return the cavity to service faster than most competitor’s systems. Polyurea has the ability to form a monolithic, durable liner which protects the cavity from infiltration into municipal wastewater systems of sediment and groundwater.
Track Containment and Railcar Lining
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.
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.
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.
Theme Park and Decorative Design
Polyurea is often used at theme parks to form protective coatings over foam, EPS and other structures to create artificial rocks, pools and environments, ornamental building fascia, and themed characters.
Flooring and Parking Decks
Because of their rapid turnaround installation capabilities, Polyurea flooring systems are most popular, and there are other important benefits for these systems as well. Being very durable Polyureas are great for use in high traffic areas. They are also used in clean or dirty rooms in order to provide waterproofing and protective coating which protects them from the pressures of daily cleaning operations. Polyurea flooring systems can even be formulated to be flexible and resilient, and this allows the system to protect objects that may fall onto to floor.
Lining for Aquariums
The benefits of Polyurea have also been applied to Aquariums. Polyurea is a desired system for aquariums because of its ability to form to properly prepared custom shaped walls and themed ornaments. 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.
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.
