What Is Polyurea Used For?


Polyureas can be sprayed or reaction-injected into molds to produce automotive fascia and bumper parts, water park slides, ornamental structures, and other features. They’re also ideal for new storage tank primary lining projects and rehabilitation efforts. Read the Best info about polyurea training.

Before applying a polyurea coating to a concrete surface, it is vital to perform careful preparations to ensure optimal adhesion. Too much moisture present could prevent a proper bond and create problems when bonding occurs.


Polyurea waterproofing coatings have become increasingly popular over time. Their long molecular chains feature strong bonds that make them highly flexible and durable while being easy to install and cure faster than epoxy coatings – meaning they can be utilized quickly for multiple applications such as concrete surfaces or other materials exposed to UV exposure, chemical attack, water vapor or thermal expansion.

Polyurea waterproofing membranes are an industry favorite for spray-applied waterproofing membranes thanks to their tough, flexible, seamless coating that resists punctures, tears, and impact damage while offering exceptional adhesion with substrates and watertight. Furthermore, they’re resistant to chemicals and oils and easy to clean, making them perfect for industrial and commercial floors.

Surface preparation must be considered appropriately before using Polyurea as a waterproof coating. Concrete will not bond well with waterproofing layers and eventually break down or degrade over time, something easily avoidable by testing for moisture content before applying waterproofing polyurea coating. If the moisture content exceeds acceptable limits, sealing or covering with waterproof barriers must occur before coating applications.

Polyurea is a hot-spray applied membrane created from the reaction between isocyanate components and amino or amino-polyol resin, producing fast and controllable reactions with multiple physical properties such as gel times, cure times, flexibility, adhesion, color stability, and other features. Available aromatically and aliphatic versions for specific application needs, aromatic versions are less sensitive to ultraviolet radiation exposure than their aliphatic counterparts.

Polyurea can be used in numerous ways. Some common examples include lining railcars and tanks with it, providing waterproofing for sewage treatment plants, protecting concrete structures from abrasion and corrosion, as well as lining and protecting concrete water containment systems; rehabilitating maintenance holes; restoring canals; protecting bridge decks against traffic damage as well as helping prevent intrusion of underground tunnels with it.

Chemical Resistant

Polyureas offer many protective properties that can improve the reliability and lifespan of equipment used in emergency response. Industries use them to prevent corrosion, impact damage, abrasion resistance, and waterproof lining on tanks, pipes, and roofs – as well as to cover equipment below the waterline on boats or for custom projects such as this lifelike Humpback whale sculpture commissioned by Sky Ocean Rescue. Polyurea spray coatings such as LINE-X are applied to emergency vehicles like firetrucks and ambulances to protect critical equipment from the elements – providing reliable waterproof linings on tanks, pipes, and roofs. Polyurea spray coatings also cover equipment below the waterline, which offers durable waterproof linings against corrosion damage. At the same time, resisting abrasion resistance and providing waterproof linings against weather exposure – these coatings also act against wear and tear.

Polyureas have proven themselves incredibly useful across numerous industrial applications. In the concrete industry, they’re commonly used as floor sealers and protection against abrasion and to repair cracked surfaces. Furthermore, they’re frequently employed on chemical processing vessels, water tanks, and slurry pits to guard against erosion or contamination and provide corrosion resistance protection – also great for protecting surfaces in warehouses, airports, or transportation facilities against impact damage.

Polyurea formulations come in many varieties, with hybrid polyureas like ISOMAT PUA 1240 and ISOMAT PUA 1360 ideal for waterproofing and abrasion resistance. All formulations require appropriate surface preparation to achieve the best performance and adhesion; this may involve blasting or chemical stripping to remove existing coatings and create an ideal substrate before the coating application.

Polyureas are applied using specialized equipment that heats and mixes its two components – isocyanate and resin – which are stored separately in 55-gallon drums. Once mixed, this mixture is then piped through heated hoses into a spray gun at a 1:1 ratio and applied directly over surfaces being protected to form an extremely durable membrane that sets within seconds to minutes – providing rapid protection that outlives traditional coatings by 8x.

Corrosion Resistant

Polyurea’s corrosion-resisting properties make them the perfect coating material for metal surfaces, protecting them from chemical corrosion, rusting, and water-borne chemicals while withstanding harsh environments typical of industrial settings.

Commercial facilities have long utilized Polyurea’s protective properties, particularly when protecting areas requiring high levels of protection with fast returns to service after application. Examples include truck bed linings, protecting concrete and steel surfaces in wastewater treatment plants, providing abrasion resistance at mining sites, and coating industrial equipment.

Polyureas have long been used as construction lining and coating products, whether through spray application, open pour, or reaction injection molding (RIM), to protect concrete structures against impact and heavy loads. They’re found on bridge decks, tunnel systems, and primary containment applications.

Polyureas are widely utilized as protective coatings on wood surfaces. They offer a long-term solution that resists scratches and scuffing, improves strength, and offers antifungal and abrasion-resistance benefits.

Marine industry applications of Polyurea have also seen great success using polyureas. Their strength and durability make them ideal for use while still floating on water, plus their resistance to abrasion, chemical corrosion, UV light damage protection, and protective features make them highly sought-after materials.

Polyurea coatings provide an ideal way to line or protect oil and gas infrastructure. They’re suitable for primary lining wastewater treatment plant tanks exposed to constant mixing, dewatering, and erosion from wastewater treatment processes; or used on cargo ships or dock structures as protection.

Slip Resistant

Polyurea is a highly durable material when designed for elastomeric properties, as its long molecular chains enable it to stretch and move with the substrate without cracking, making it a fantastic slip-resistant coating option. If you plan on using it in commercial or residential projects, consult a professional regarding what surface you will coat, as inappropriate coating could lead to cracking in future years.

Polyurea’s durability and slip-resistance properties make it the ideal material for coating surfaces that experience heavy traffic or direct exposure to weather, including walkways and parking garages. Compared to traditional coatings, polyurea coatings can withstand impact from vehicles, machinery, foot traffic, snowfall, and raindrops, and cure quickly, saving businesses days or weeks of lost revenue during downtime.

Polyurea’s versatility has resulted in its use across various industrial and commercial environments. For instance, Polyurea can be used as a waterproof barrier in bridges and tunnels or lined water tanks and as an insulator, providing corrosion protection to concrete and steel structures.

Polyurea’s chemical, corrosion, and abrasion resistance makes it ideal for mining use; conveyor belts, dump truck waves, and steel surfaces require protection from coal and metallic ore transportation, concrete floors in oil & gas facilities, and steel surfaces at oil & gas facilities all benefit from its application. Furthermore, the military uses Polyurea as an explosion protection measure against mine explosions or bomb impacts. At the same time, some recently developed polyurea-based materials can even self-heal after chemicals or explosive damage has occurred, an incredible technology that has already saved lives on many occasions!
