Painting of metal structures with zinc-containing paints and enamels

Painting of metal and metal products Painting of metal and metal products must be carried out correctly and efficiently. Not every surface is suitable for every paint. In order to choose the right type of painting, you need to follow some steps. To properly paint metal structures, you need to choose a coating with anti-corrosion properties. In this case, you need to understand which metal needs to be painted. Painting of metal structures with zinc-containing paints and enamels. Zinc-containing paints are a composition for the cold galvanizing method; paint containing zinc is anti-corrosion and extends the service life of the metal. Ferrous metals, namely iron, are mainly painted with oil and alkyd paints. Iron rusts quickly and needs to be coated. Alkyd primers with the addition of zinc are considered the best in terms of stainless properties. Technology of painting metal structures and metal products For high-quality application of the selected paint, it is necessary to prepare the surface. It should be dry. Therefore, weather conditions play an important role. It is necessary to get rid of rust: Mechanically, use sandpaper. Chemical exposure, various solutions with a high content of phosphoric acid. Using sandblasting. For better adhesion, a surface primer is necessary. This will protect the metal from rust. The choice of paint is very large. We must not forget about such qualities as heat resistance and corrosion resistance. Apply paint in 3-4 layers. Before starting, be sure to check compatibility in a small area. Apply paint to complex and small coatings with a brush, increasing the number of layers to 5-6. Each layer is applied at intervals of 15 minutes. Aerosol cans are used for tinting and painting small parts. Powder paint Powder paint is used to strengthen any metal products. It does not contain chemical additives and is considered environmentally friendly. If all stages of painting are followed, it will last for many years. Heat-resistant enamels Heat-resistant enamels up to 1000 degrees are used to protect pipe radiators, metal stoves and other heating circuits. Also, heat-resistant enamels give a beautiful appearance to the product. You can buy these types of paints directly from the manufacturer or order them on the website at the best price.
