Why Flow Coating Over Spray Painting?

    Would it be satisfactory for you if you just cleaned the left side of your body while bathing and not the right side? Of course, not. Similarly, using spray paint to paint the substations and transformers is like doing an incomplete job and keeping the substation prone to risks. Let us examine why flow coating is the right option to go for:

    The contrast between spray painting and flow coating

    When it comes to painting substations flow coating is always preferred. Spray painting involves the use of spray guns, automated liner spray systems, and automated flatline spray systems, etc. On the contrary, flow coating involves applying a massive amount of the coating material to the substance in order to provide complete coverage and the surplus coating material is collected separately for reuse. Spray paint covers only about 50 to 75% of the area which means that there is a high risk of corrosion to the remaining part making it vulnerable to an electrical malfunction. As per the experts at, flow coating ensures 100% complete coverage of the substations and transformers making it cost-effective and extending its life expectancy. Also, automated spray machines can not always be carried to the desired location, however, flow coating is applied to the location without disassembling the equipment

    Protection of metal

    Various metals are reactive to gases present in the air. When the area of the substation and transformer which has not been painted properly, reacts with these gases, a layer of rust is formed which can become an obstacle in the power supply provided by the substation. If not taken care of, it can also lead to electric fires and shocks. So it is significant to choose the right service provider for flow coating to protect the substation from such hassles as it covers the restricted and tiny surfaces which are difficult to reach including all the fins, tubes, joints, and hidden areas.

    Improved efficiency of radiators

    Radiators of transformers play an important role in their smooth functioning by cooling down the excessive heat produced by the transformers. Using spray painting, a thick layer of paint is built on the radiator. This disallows the radiators to cool the heat generated in the transformers, reducing their efficiency to work properly, Flow coating involves thinning of primer and finish coat paint so that a thin layer covers the radiators, allowing the heat to cool down and increasing the proficiency of the radiators.


    The process of flow coating is considered to be safer than that of spray paint. A protective wrap is covered around the transformer to protect the sensitive areas before starting the work. Not one but different layers of thin paint are applied to prevent the corrosion of zinc. The process of flow coating is easy as it allows no disruption in the functioning of the substation. The technology and the effective work measures used in the process offer great security to the workers. At last, after the final layer of coating, a quick clean up takes place to provide a clean finishing.

    There is not one but many reasons to choose flow coating over spray painting as it is cost-effective, safer, trouble-free, and provides better coverage. In the end, keep in mind that choosing a flow coating is a wiser option in the long run.
