What paint is sprayed on the surface of galvanized steel?

As a kind of material widely used in construction, transportation and industrial fields, galvanized steel's anti-corrosion protection is very important. Under normal circumstances, in order to extend the service life of steel and prevent corrosion, people will use paint to paint it. However, during the construction process, the construction personnel often encounter a thorny problem, that is, the problem of falling off the paint. After the steel is galvanized, its surface will become very smooth, which makes it difficult for ordinary coatings to adhere firmly to the surface of the steel. When the paint film is easy to fall off, it is impossible to form a continuous and effective protective layer on the steel surface, so that the desired anti-corrosion effect cannot be achieved.

In order to solve this problem, the anti-corrosion coating of galvanized steel requires the use of specially designed primer, which must have a strong adhesion to the galvanized surface to ensure that the paint film will not fall off. ED1000 epoxy primer is such a special primer, which not only has excellent adhesion, but also has a strong adhesion ability to galvanized substrates. The use of ED1000 epoxy primer as the base coat ensures that the coating does not fall off, and can be used in conjunction with medium and top paints to form a composite coating system that not only provides excellent protection, but also enhances the decorative properties of the material.

The main feature of ED1000 epoxy primer is that it has excellent adhesion to various metal substrates, such as galvanized steel, stainless steel, aluminum alloy, aluminum plate, etc. This feature effectively solves the peeling problem encountered by many users during the painting process. In addition, the primer also has a high solid content, does not contain heavy metal raw materials, and can be constructed by spraying, brushing and other processes. The adhesion of the film has been verified by many test methods, such as grid method, circle method and drawing method, and all meet the relevant standards.

ED1000 epoxy primer is a two-component paint with a grey film. When the main paint is mixed with the curing agent, a cross-linking curing reaction occurs to form a tough paint film that provides a strong protective layer for the metal substrate. This primer can be compatible with fluorocarbon, epoxy, polyurethane, acrylic and other types of top paint, the combination of primer and top paint is good, not only can protect the primer to adapt to different indoor and outdoor environments, but also can play a good decorative effect.

In the anticorrosive coating scheme of galvanized steel structure, ED1000 epoxy primer can be used in combination with epoxy cloud iron intermediate paint and acrylic polyurethane topcoat, or directly combined with acrylic polyurethane topcoat to form a system structure to achieve long-term protection effect. Only on the premise of ensuring the adhesion, can we ensure the high-quality coating effect and meet the requirements of high standards of corrosion protection. Through such a coating system, the corrosion protection of galvanized steel will be more reliable, thereby extending its service life, reducing maintenance costs, and improving the overall economic benefits.
