Coatings and coating systems act as a barrier to different harmful chemicals such as sodium sulfate, sulfuric acid, and ammonium, and prevent moisture penetration. This quality makes coatings an excellent way to protect concrete.
Coatings are often used in different machines such as filter beds, aerators, clarifiers, toughs, tanks. They are also utilized on anything that comes in contact with water and chemicals.
There are many different types of coating systems for water and wastewater treatment applications. In this article, Zebron discusses three of the most popular choices in coating systems.
Polyurea and Polyurethane Coatings
These types of coating dry quickly and do not depend on temperature for its curing process. They are known to perform very well in treatment plants as well as in immersion service. Installing polyurea and polyurethane coatings can be quite complicated, though, which is why you should consider calling a professional to do the work for you. DIY is not really the best option for this type of job.
Polyurethane can be applied on many surfaces such as wood, metal, plastic, and even to any flooring surface. It can seal out dirt, mud, rain, and even oil and solvents. This type of material also does not emit vapors that can be harmful to people and the environment, so you can both protect your family and be environment-friendly as well.
Coal Tar Epoxy
Coal tar epoxies can be used on concrete and steel. This coating is typically used to protect or coat the material against mild chemical attacks and abrasions. It can be used on bare concrete and can be applied using only a roller, brush, or even spray.
Two-component epoxies have high solid contents, which makes them extremely hard and durable as coatings. They can adhere to different chemical reactions such as abrasion, contaminate spills, and chemical attacks. This type of material can be used for immersion service on concrete and steel. It is also known to be easy to clean out.
Coating systems can be dangerous and difficult to work with. To be safe and to know which one you should use, make sure to contact your local coating system contractor and ask for their help in doing the job.
