Polyurea Coating Formulation Techniques
Polyurea coating is a revolutionary new joint sealing and coating technology. It’s being used successfully for a variety of different applications in modern industry today. Polyurea linings and coatings are most commonly applied over steel and concrete for corrosion protection and abracement resistance. A polyurea coating is also excellent for resisting oil, grease and water penetration throughout your facility. The polyurea coating can also be beneficial for protecting the steel framing and foundation of buildings and even concrete slabs. Polyurea coating can be used for many purposes including protecting concrete slabs from the destructive effects of weather, fire, and vandalism.
When applying polyurea coating or a polyurea liner to a surface, there are several steps that must be taken before the coating is applied and cured. All polyurea coating application processes and materials must be performed in the correct and proper manner. All polyurea coating and formulators must be pre-drilled for proper and safe installation. Drilling is critical because the polyurea coating and formulator must be seated on a smooth, flat, level surface. Formers and holes need to be drilled in the proper location before the coating or formulator is installed.
All polyurea coating and formulators should be mixed using a high temperature and chemical formula to achieve the proper viscosity for the application needed. Once mixed, they should be heated to their boiling temperature and allowed to cool slowly. The polyurea coating and formulator must then be allowed to cure in a controlled environment using either an ultraviolet curing or an ultra violet curing process. Once the curing process is complete, the polyurea coating or formulator should be cleaned with water and a mild dish soap.
After the cleaning process is complete, a fining agent should be added to the coating to achieve a consistent film thickness. Formulators must then heat-dissolve the polyurea coatings or formulators must be brushed with an abrasive brush to remove excess dirt from the surface of the coating. After the coating has been cured, a clear protective layer will be cured on the surface, and the coating can then be painted or polished to achieve the final color and gloss desired.
Polyureas are used in many industries such as construction, coating roofs and flooring, chemical industry, marine, chemical transportation, and many others. Due to their low cost and high level of hardness, polyurea is highly sought after for construction projects. It is also used for the manufacturing and transportation industries to provide a long lasting, strong, barrier-free coating. Polyureas are also commonly used in the automotive industry as floor coating because of its chemical resistance and low level of viscosity.
Some polyurea coatings have a higher level of thermal shock resistance than others. This is due in part to the chemical resistance, which makes it more resistant to abrasion than traditional foams. Some polyurea formulations are commonly used for coating concrete while others are commonly used for applications requiring a bumpy or crumbly finish. Polyureas are most commonly used in concrete projects where they are used in milling and crushing. They are commonly used as additives to reinforce concrete slabs and as a lubricant between rotating machinery parts, particularly those that are sensitive to high stress.
