Polyurea Coatings

Polyurea is an organic polymer that is the reaction of isocyanate with an amine terminated polyether resin, forming a plastic-like or rubber-like compound that may be used in many of the same ways as older technologies – polyurethane, epoxy, vinyl ester, neoprene; to name a few.

What is Polyurea?

A polyurea coating/elastomer is that derived from the reaction product of an isocyanate component and a resin blend component. The isocyanate can be aromatic or aliphatic in nature. It can be monomer, polymer, or any variant reaction of isocyanates, quasi-prepolymer or a prepolymore. The prepolymer, or quasi-prepolymer, can be made of an amine-terminated polymer resin, or a hydroxyl-terminated polymer resin.

The Resin blend must be made up of amine-terminated polymer resins, and/or amineterminated chain extenders. The amine-terminated polymer resins will not have any intentional hydroxyl moieties. Any hydroxyls are the result of incomplete conversion to the amine-terminated polymer resins. The resin blend may also contain additives, or non-primary components. These additives may contain hydroxyls, such as pre-dispersed pigments in a polyol carrier. Normally, the resin blend will not contain a catalyst(s)



Polyurea protective coatings are commonly used for the following reasons:

Each year, corrosion and water damage effects every corner of the globe. Annual damage costs run in the hundreds of billions of dollars. Studies show the total annual estimated direct cost of corrosion in just the U.S. is a staggering $276 Billion, approximately 3.1% of the nation’s Gross Domestic Product (U.S. Federal Highway Administration & NACE International). The good news is much of this damage is preventable.

Industrial waterproofing provides critical protection to facilities and structures that are vulnerable to the natural threat of intense water damage, flooding, or corrosion. SPI’s advanced polyurea coatings protect a variety of construction materials (various metals, concrete, wood, glass, polyurethane foam, geo-textile fabric, and more). These durable elastomeric coatings form an impermeable barrier that is resistant to corrosion, water, and many chemicals. Investing in the right coating technology will greatly extend your investment’s service life at a fraction of the replacement cost.


Food and Agriculture

The multi-billion dollar Food and Agriculture Industry plays a vital role in feeding the world’s population. The infrastructure needed to take the raw food from the farm to your dinner table ensuring it’s safe to eat requires a significant investment. In the U.S., the FDA and Food and Agriculture Industry work closely together to mitigate this public health threat. Unfortunately, cleaning processes don’t always stop food contamination, as bacteria can find its way into nooks and the smallest of quarters. Expensive processing equipment can also be prematurely worn down from accelerated corrosion and abrasion damage due to repeated cleaning and everyday wear and tear. The Food and Agriculture Industry needs a reliable coating solution to protect and extend the service life of their investment.

SPI’s polyurea protective coatings are FDA – 21 CFR 175.300 (c)/ (d) certified for direct food contact. These fast-set elastomers create a high strength, waterproof, flexible, seamless membrane that protects concrete, wood, metal, and many other surfaces. They provide a durable surface that can withstand repeated power washing and are resistant to many sanitizing chemicals.


  • Protect surfaces in food processing plants and facilities
  • Food and beverage interior storage tank linings
  • Food transportation liner for semi-truck trailers and railroad cars
  • Non-slip surface for floors, walkways, and loading areas

Industrial Floors

Industrial floors, loading zones, parking garages and other high traffic areas are constantly exposed to heavy wear and tear. Forklifts, vehicles, equipment, foot-traffic, everyday operating conditions, even spills of chemicals or other substances can prematurely damage floor surfaces. Slippery surfaces or damaged floors with uneven areas can also create potential fall hazards. Repairing or replacing existing floors can be expensive and create costly operational downtime.

SPI’s elastomeric protective coating solutions provide a tough, impermeable, seamless barrier that extends the floor’s service life at a fraction of the replacement cost. These ultra high-strength, flexible coatings are able to move with substrate expansion and contraction. They provide a durable surface that is abrasion resistant and able to withstand repeated power washing and cleaning. Non-skid or slip resistant surfaces can also be achieved to help minimize fall or trip hazards. The fast-set or rapid curing properties of the coating allow for a quick return to service.
