Analysis of Supporting Scheme of Epoxy Zinc-rich Primer

Epoxy zinc-rich primer is a coating that is widely used in anti-corrosion projects. It can be used with a variety of topcoats to further improve the anti-corrosion properties of the coating. Let's take a look at the application effect of epoxy zinc-rich primer and various topcoats!

Ⅰ. Which topcoat is better with epoxy zinc-rich primer?

1. Matching with epoxy topcoat

The paint film of epoxy topcoat is tough, has good adhesion, and has good wear resistance, alkali resistance, anticorrosion and decorative properties. However, because the weather resistance of epoxy topcoat is not good enough, this package is more suitable for indoor environment substrate coating.

2. Matching with fluorocarbon paint

Fluorocarbon paint is a kind of paint with high comprehensive performance. Its anti-corrosion and weather resistance is long, its decorative effect, acid and alkali resistance are outstanding, and it has good adhesion to a variety of substrates. Therefore, the combination of epoxy zinc-rich primer and fluorocarbon paint is often used in the coating of outdoor steel structures, bridges, buildings and other heavy-duty anti-corrosion fields.

3. Matching with acrylic polyurethane topcoat

Acrylic polyurethane topcoat has a plump film, good anti-corrosion effect and moderate price. It is a commonly used topcoat in the field of anti-corrosion. It is mostly used for anti-corrosion coating of large machinery and equipment, coastal facilities, factory buildings, containers, etc.

In addition to being used with the above topcoats, the epoxy zinc-rich primer will also form a complete matching system of primer, intermediate paint and topcoat together with the epoxy micaceous iron intermediate paint.

Ⅱ. What are the common supporting schemes for epoxy zinc-rich primers?

Epoxy zinc-rich primer is one of the most widely used products in industrial anti-corrosion. Which topcoats are it usually used with?

1. Epoxy zinc-rich primer + epoxy micaceous iron intermediate paint + fluorocarbon topcoat

The durability, anti-corrosion, and protection are outstanding, and are generally used in high-speed railway stations, airports, workshops, bridges, ports and other equipment and facilities.

2. Epoxy zinc-rich primer + epoxy micaceous iron intermediate paint + acrylic polyurethane topcoat

The matching anti-corrosion, acid and alkali resistance, mechanical properties are more prominent, generally used in bridges, buildings, machinery and equipment.

3. Epoxy zinc-rich primer + epoxy micaceous iron intermediate paint + chlorinated rubber topcoat

This set is resistant to acid and alkali salts and has outstanding corrosion resistance, and is generally used in chemical plants, mechanical equipment, ports, etc.

4. Epoxy zinc-rich primer + epoxy micaceous iron intermediate paint + aliphatic polyurethane topcoat

It is suitable for the anti-corrosion of the steel structure of thermal power plants, but due to the different use requirements of each part of the steel structure, it is recommended to consult the manufacturer's technology for specific paint matching.
