Here are 5 facts about fast-setting polyurea spray systems:
1. Polyurea Spray Coatings Serve a Wide Range of Industries
The use of Polyurea Spray Coatings ranges from mining channels to sporting grounds. This type of spray meets the needs of a host of industries, such as:
Construction industry, for erosion protection, concrete surface protection and waterproofing.
Manufacturing industry, for surfaces protection.
Water industry, for storage tanks and pipeline corrosion protection.
Chemical industry, for processing vessels’ corrosion protection and chemical-resistant tank liners.
Concrete industry, to provide floor sealers, protective coatings, surface repair, or waterproof surfaces.
Military industry, for outdoor dwellings reinforcement.
Oil and gas and coal mining industries, for abrasion resistance and corrosion protection.
This list represents only a small sample of a large number of industry uses.
2. Polyurea Spray Coatings Have Different Functions
Polyurea Spray Coatings can be used for different purpose even within a single market niche.
For instance, a railroad company may use one polyurea system to prevent an aggregate from damaging the surfaces of railcars on impact and use a different system to prevent corrosion of other metal surfaces.
Other functions include:
Enhancing the strength of a part or protecting surfaces from wear and tear, like in truck bed liners.
Waterproofing surfaces of a swimming pool or a reservoir.
Protective coatings for wood surfaces to prevent scuffing and scratching.
Reinforcing fabrics or padding for durability, such as roofing materials and military garments coatings.
Softening or hardening a surface, such as a tabletop, with a spray-on coating for a softer feel or improved impact resistance.
Protecting tunnel surfaces from impacts and blasts.
Providing environmental and rust protection for metal surfaces.
From small, spray coated fracking aggregates to large-spray coated mining or highway passages, there is a vast number of applications where polyurea spray coating systems are being used.
3. Polyurea Spray Coatings are a Material of Choice for many Applications
Between their endless industry uses and numerous functions, it’s not surprising that fast-setting Polyurea Spray Coatings also have a variety of applications. Here are a handful of examples:
Spray coatings for truck-bed liners or concrete-mixing tanks liners.
Underground level surface spray layers that create a waterproof barrier for sewage tanks, buildings, or construction purposes
Sand or rock surface spray layers that provide erosion protection for golf courses or playgrounds and help maintain a beautiful landscape
Decorative applications, including car coatings or even high-end car waxes
Fertilizers (processed by) spray coatings of polyurea which offer a unique time-release from the gradual decomposition of the thin film of polyurea
The potential for polyurea spray coating applications is ever expanding. Choosing the right spray polyurea system will ensure a long-lasting surface protection for many different applications, regardless of the shape or size.
4. Polyurea Spray Coatings Have Different Forms
The finished layers of fast-setting polyurea spray coatings can have a different hardness, depending on the formulation. They can be a foam or elastomeric, clear or colored, matt or glossy, hard as glass or softer than rubber, structured with fillers or a very thin film.
It simply depends on what are the requirements of a particular application.
A distinct form of polyurea spray coating and environmental-resistance properties can be achieved by choosing different chemicals or their combinations.
5. Polyurea Spray Coatings can be Customized for Specific Uses
Though all spray coatings are applied in a similar way using high-pressure spray guns, longer gel-time formulations can be applied with rollers. Altering the formulation enables customization for a specific application.
The environment, intended function, hydrolytic resistance, static or dynamic nature of the application, thermal shrinkage, operating temperature range and other variables should all be considered for an adequate material selection.
Here are a few questions that should be considered:
What kind of protection is required?
Does the application require impact or abrasion resistance?
What type of abrasion is predominant: sliding or impingement?
Is the nature of the application static or dynamic?
Is resistance to direct sunlight and UV exposure important?
What is the expected operating temperature range?
What kind of chemical exposure should be expected?
Is hydrolytic resistance important? Operation in hot and humid environment?
For instance, a bathroom tub application will require different formula than a swimming pool application since the latter requires more UV resistance and chemical (chlorine) resistance. However, those formulas will be quite different from the abrasion-resistant coating needed for a fracking slurry pipe liner. Yet all three applications need good hydrolytic resistance.

Choosing the right coating for your industrial assets is important. The right choice could mean added useful life and less maintenance for key assets. The wrong one might lay the groundwork for untimely and costly failures.
Foreknowledge of which coatings are better suited for different environments and job specifications is key to an efficient and effective coating job. Let’s compare epoxy and urethane coating systems, a longtime staple of industrial asset protection, to polyaspartic technology, a hybrid coating type increasing in popularity because it can limit lag time and reduce costs.
Epoxy and urethane coating systems offer two layers of protection over a surface. These perform well in heavy industry settings because they’re more tightly cross-linked and less permeable, offering good substrate protection, increased chemical resistance and greater hardness. Due to these qualities, metal and concrete substrates protected by epoxy and urethane combinations stand up well to use and abuse.
Epoxy and urethane coatings also can tolerate exposure to many industrial chemicals. For instance, surfaces protected by epoxy and urethane coatings stand up well against sulfuric acid, which is used in a wide variety of industrial processes. However, certain organic acids present in food production, such as nitric acid, can harm epoxy and urethane coatings.
Epoxy and urethane coatings are well-suited for interior spaces with controlled environments.
Relatively new on the industrial coatings scene is polyaspartic technology, a hybrid coating similar to polyurethanes. Innovations in the technology have made these coatings a more versatile option compared to epoxy and urethane coating systems. Applying polyaspartics in a single coat accomplishes what traditional epoxy and urethane systems need two coats to do. The technology has come a long way as early polyaspartic formulations had low adhesion values. Well-known system failures have been blamed on this lack of adhesion promoters in early polyaspartic technology.
Polyurethanes are softer, more flexible and offer better color and gloss retention. They perform well as structural protection, are more versatile in terms of protecting assets in harsh weather conditions and offer better impact resistance than epoxy and urethane coatings. For example, tanks, exterior pipes, barges or exterior concrete are better protected with polyurethane coatings.
Polyaspartic technology breaks from traditional polyurethanes because polyaspartic esters can be manipulated to suit varying applications. Manipulating the esters allows for controlled drying times and extends potlife. Where epoxy and urethane coatings require much longer curing times, polyaspartic coatings cure much more quickly. That limits lag time, allowing assets to be put back to use more quickly. Polyaspartic coatings also can be formulated for application and curing at temperatures well below freezing.
Polyaspartic technology eliminates a step in the coating process compared to epoxy and urethane combinations, saving labor and material costs and shortening project timelines.
Because lower- and zero-VOC coatings can be achieved with polyaspartic technology, it’s safer to apply in confined spaces like storage tanks, railcars or pipes where ventilation is minimal. This also can save on taxes levied against high VOC outputs. MBOEA, P-1000 and liquid curative formulations.
Applications That Use Powder Coating
Powder coating isn’t solely used in construction. If you look at your home appliances, you will see that they come with high quality painting. Mostly, it is scratch resistant and can even withstand a dent without chipping off. This is because they have been powder-coated.
Powder coating makes painted architectural steel parts resistant to heat damage, cold damage and even corrosion. The reason why you see an old balustrade or steel bench still baring its original paint is because it was powder-coated. Powder coating has been used for finishing metal items since the 1950s.
Most of metal products designed to be used outdoors are finished using the powder coating method. For example, tractors and other farm machinery are finished in such a manner that even exposure to extreme temperatures does not affect them. The same goes for a wide range of industrial machinery.
Metallic roofs and curtain walls can also be powder coat finished. That way, the surface retains its appeal for many years after construction.
Golf carts, lawn chairs, cycle shelters and most metallic outdoor furniture is finished using the process of powder coating.
Road and direction signs are also made with this process. That is why they are still standing many years after they were erected, without showing signs of fading or corrosion. Powder finished products do not age and they do not corrode, no matter how much exposure they face.
Metal cabinets for offices, office chairs and desk parts are all powder coated. This makes sure that they retain their appeal for the longest time possible. Other things in the office that are powder coated include fire extinguishers, which retain their colour even if they have been used to put out fires.
Most high usage car parts, like the door handles, window handles, bumpers and other parts are also powder coated. Radiators coil springs, shock absorbers and braking parts are also powder coated as they are mostly the contact parts of a car. Wheels, frames and other parts that face stress are also more likely to be powder coated.
Powder coating is the most used type of protective finish in the world as it is used in almost everything in our life.
