Spray coating is a process where a liquid material is applied to a surface using a spray gun or similar device. This technique allows for an even and uniform application, making it ideal for covering large areas or complex shapes. Common materials used in spray coating include paints, varnishes, and protective coatings. The spray coating process is widely used in various industries, including automotive, aerospace, and construction. It helps enhance the appearance and durability of products by providing a protective layer against environmental factors like moisture and UV rays. Additionally, spray coating can improve adhesion and reduce the need for multiple application layers.
