Galvanized pipe, also known as galvanized steel pipe, is mainly used for conveying gas and heating, which is generally divided into hot-dip galvanizing and electro galvanizing. The zinc coating on the surface of galvanized pipe can prevent the corrosion solution from directly contacting with the steel substrate, which can protect the substrate. Galvanized pipe as an important part of industrial production, coating anticorrosive paint on its surface can extend the service life of galvanized pipe, generally choose epoxy zinc yellow primer.
Whether it is hot-dip galvanizing or electro galvanizing, the surface of galvanized pipe will become extremely smooth once it is galvanized. Therefore, the general anti-corrosion paint simply can not adhere to its surface, even if attached, it is very easy to fall off. The epoxy zinc yellow primer can be said to be a special coating for galvanized pipe, which has strong adhesion and no pressure on the smooth surface of galvanized pipe.
Many people say that the galvanized pipe is already coated with a layer of zinc, which can protect the substrate. Why should we brush an extra layer of anticorrosive paint? Yes, the purpose of galvanizing is to protect against corrosion, but only one layer of zinc is not enough. It is very necessary to provide double protection for galvanized pipe, especially for industrial places with serious corrosion.
Epoxy zinc yellow primer not only has excellent anti-corrosion effect, but also has good decorative effect. The product is zinc yellow, the film is bright and full, the visual effect is very beautiful. In this way, it can provide a more convenient choice for users who have higher requirements for decorative effect.
