Performance Advantages of Steel Primer Surface Brush Epoxy Primer

Author:    Date:2017/10/26 15:06:06

Epoxy primer and alkyd anticorrosive primer with the commonly used primer anti-corrosion products, but both in the anti-rust performance, functional role, supporting and other aspects are very large In contrast, epoxy anticorrosive products have a wider range of coating and use of the environment, usually with high-performance anti-corrosion finish, and alkyds are only applicable to the requirements of anti-corrosion coating. Steel has a wide range of applications, in different areas of the coating environment, the intensity of corrosion is different, anti-corrosion paint compared to anti-rust paint in terms of a stronger anti-rust effect, the coating environment is also very broad, more consistent Steel structure of the anti-corrosion anti-rust coating requirements, the following is different for the steel structure of the anti-corrosion coating, steel surface can be divided into three kinds of environments using different paint to achieve rust and corrosion.

1, bridge steel structure (common type): primer is epoxy zinc phosphate primer, the middle paint is epoxy cloud iron intermediate paint, finish is acrylic acrylic polyurethane paint

 2, the bridge steel structure (long-term): primer is epoxy zinc-rich primer, the middle paint is epoxy cloud iron intermediate paint, finish is silicone silicone

 3, plant steel structure: primer is epoxy anti-corrosion primer, the middle paint is epoxy cloud iron intermediate paint, finish is fluorocarbon topcoat


More than a few supporting programs are more common anti-corrosion package, according to different environments choose different anti-corrosion paint such as: high-rise building steel, steel structure, etc., if not in a strong corrosive environment, the general choice of corrosion products are mostly ring Oxygen zinc yellow / iron red primer, epoxy coal tar pitch paint, etc., if the harsh environment of the steel structure, the general choice of epoxy zinc-rich primer mostly.


In addition to understanding the surface of the steel structure according to the different use of the environment listed in the anti-corrosion package, but also do a good job in the face of steel corrosion preservative decline in response strategies, to find remedial measures before we should know the paint gloss decreased s reason:

1, anti-corrosion coating system is not appropriate rheological properties, so that after the brushing wet film can not smooth leveling (orange peel phenomenon).

2, the crystal structure of the pigment also has a role in gloss. That is, the distinguished crystal of crystal crystals to prevent the full smooth coating. With the right way in the straight line crushing outstanding water chestnut to restore the normal length of the pigment crystal also return to the same size with other particles, just the degree can also be substantial progress.

3, paint concentration is too large.

4, the pigment is not diluted, anti-corrosion paint is still there is a lot of pigment particles or a lot of pigmented coalescence appearance.
