Polyurea is a type of elastomer that is derived from the reaction product of an isocyanate component and a synthetic resin blend component through step-growth polymerization. The isocyanate can be aromatic or aliphatic in nature. It can be monomer, polymer, or any variant reaction of isocyanates, quasi-prepolymer or a prepolymer. The prepolymer, or quasi-prepolymer, can be made of an amine-terminated polymer resin, or a hydroxyl-terminated polymer resin.

The resin blend may be made up of amine-terminated polymer resins, and/or amine-terminated 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).

Gas Island Rehabilitation Trop-Eco has developed a process of re-furbishing and coating the concrete and steel islands Fuel dispensers sit on at gas stations. It offers a better looking gas island and protects it from rust, corrosion, extended life and vehicular damage. It is a great application for islands who have previously suffered damage and also new islands that need a spark to look better while being protected. The islands can be top coated in a UV resistant top coat in practically any color and will not fade with time or lose its good look, unlike a uncoated pump.

Pipe Linings Trop-eco has developed a robot capable of traveling deep into pipelines to coat the inside of aging or damaged pipe. With our country’s infrastructure reaching its effective life span, our products can rehabilitate and repair versus the costly alternative of replacement.

Roof Coating Trop-eco’s roof coatings are applied seamlessly over a roof to provide unmatched waterproofing and insulating qualities. Having a roof coated with polyurea can provide savings on energy and cooling costs by insulating the building from the elements.

Waste Water Facilities Polyurea has high chemical and abrasion resistance making it perfect for the harsh environments of waste water facilities.

Tank Coatings Polyurea coatings protect storagel tanks from corrosion, chemicals, and other natural and unnatural elements. Polyureas are great for extending the life of older tanks and can offer limited structural characteristics as well. Polyurea linings can be applied during primary construction or tanks already in use can be coated as well. With their fast cure times they are ideal for retrofit since down time is significantly minimized compared to some competing materials.

Marine Above or below the water line, polyurea can be very effective in protecting steel, aluminum, and fiberglass in a variety commercial marine applications. Polyurea is ideally suited for hull protection and bilge liners, polyurea is used in many abrasion, chemical and corrosion resistant marine applications.

Truck Bed Liners Polyurea truck bed liners form a durable, water and air-tight, permanent liner for the exterior of pick up trucks, dump trucks and steel containers. These durable, easy to clean and abrasion resistant liners protect utility trucks from their harsh duty environments. They also protect against rust and corrosion from damaging trucks and containers. Polyurea liners can also be applied in varied thickness to meet any specific application demand. Sprayed on truck bed liners are available in many colors and can be wrapped over the top edge of the truck bed to provide added protection from impact and abrasion.

Bridge Coating Polyurea lasts longer and protects stronger against corrosion and rust than other coatings making it ideal for the harsh environments many bridges are in. The most common applications of polyurea coatings on bridges are over steel and concrete.

Railcar Lining & Track Containment Polyureas are commonly used to line liquid containment railcars for their waterproofing and chemical resistance benefits. Hopper style rail cars have benefited from the strength of polyurea and its ability to resist abrasion. These cars often carry coal, sand, and other abrasive materials. Polyurea can be applied quickly and it will last longer.

Fuel Storage & Containment Polyurea is resistant to many fuels and chemicals. It is commonly used in fuel pits and pipeline secondary containment. Polyurea is not resistant to all chemicals and necessary compatibility tests and surface preparation are always required.

Utility Vehicle Coatings 
As anyone with a utility vehicle, ATV or buggy, knows, there equipment is exposed to some harsh elements. Polyurea can provide a excellent shield from rust, water intrusion and general wear and tear. It can be applied at any thickness and texture, from nonskid to a smooth glossy finish. 

Restaurant Kitchen and Bar Floor Coatings 
Polyurea can provide a waterproof, slip resistant and sanitary environment on a floor. Washing the floor at the end of business hours can become a simple task and the texture will provide a safe working environment.
