Polyurea coating provides flexible heavy-duty protection
Despite being nearly three years old, polyurea coatings are still relatively new. However, polyurea's durability, flexibility and flexibility meant that it quickly made a name for itself and is now used in industries such as waterproofing, corrosion protection, sealing (secondary, water and chemical), flooring and mechanical equipment. Just to name a few. Polyurea coatings are also versatile and can be applied to a variety of substrates including concrete, metal, wood, plaster, plastic, and more.
Advantages of Using Polyurea Coatings
Polyurea coatings are the result of a reaction between an isocyanate and a resin mixture that forms a plastic or rubber-like compound. Elastomers produced by the polyurea reaction can be used in a similar manner to other technologies such as polyurethane and epoxy resins, but the protection offered by polyurea resins combines the best aspects of both coatings. Polyurea coatings are used in everything from mining equipment and pipeline coatings to playground fixtures, waterproof tank linings, asbestos encapsulation and more. Advantages of polyurea include:
100% solids – 1:1 by volume, requires no additional coating, and being solvent free means it's also VOC free and environmentally friendly.
High Resistance - Polyurea coatings provide chemical, abrasion and UV resistance and are able to withstand extreme temperature changes.
Water and Corrosion Protection - Polyurea paints and coatings are moisture/humidity resistant. They have low permeability and are resilient to water, providing corrosion protection.
Fast Laying and Quick Return to Service - A cure time of seconds or minutes means almost instant return to service with many times less downtime than with another coating.
Strength and flexibility – polyurea coatings have high polymer elongation, meaning it can stretch and resist punctures and tears
Thermal Spray and Polyaspartic Coatings - Polyurea Coating Application Technology
"Thermal spray" is another name for the polyurea spray process because polyurea is effective when heated to 140-160°F. The polyurea reaction is immediate and the coating begins to cure within seconds. Therefore, in order to achieve the heat and speed requirements, these two components are pumped into a special Spray Gun through heated hoses. They are mixed in the gun chamber where the reaction starts and then immediately sprayed onto the substrate. This ensures better performance and stronger physical properties of the coating.
Polyurea thermal spray coatings are suitable for use in a wide range of temperature and humidity environments. It can be used in sub-zero temperatures or on wet substrates without altering its effectiveness. It can also be applied in any thickness in a single application. Although polyurea coatings are almost primarily applied using spray equipment, polyurea coatings can also be modified to allow roller and brush application. This polyurea coating is known as polyaspartic polyurea and is commonly used as a floor coating
