Why should epoxy zinc rich primer be used with intermediate paint and topcoat?

<> Legway epoxy zinc-rich primer.

Epoxy zinc-rich primer contains "zinc", "zinc" has the effect of cathodic protection, but its weather resistance is relatively poor, and it is only suitable for primer practice. The matching intermediate paint can enhance the anti-corrosion performance, and the topcoat can play the role of anti-corrosion and decoration.

Primer, intermediate paint, and topcoat, each of which is closely linked, and if there is a lack of coating, the performance will be weakened. When buying paint, it is recommended to do it according to the manufacturer's requirements, after all, the manufacturer has obtained the best way in countless experiments.

Legway coatings.

Focus on industrial anticorrosive paint for 25 years, the introduction of foreign imported raw materials and production mode, real international quality, domestic **, welcome to consult.

Epoxy zinc-rich primer is through the electrochemical reaction of zinc powder to achieve good anti-rust performance, usually the primer needs to be tightly combined with the steel substrate to obtain excellent adhesion and no paint off. Why use intermediate lacquer? Coating with epoxy zinc-rich primer is mostly for long-term, important steel structure buildings.

For example, steel bridges, steel structure buildings, offshore platforms, etc. This determines that the thickness of the paint coating should not be too thin. Moreover, ISO12944 requires the thickness of paint coating for different corrosion environments and different anti-corrosion periods.

The main function of intermediate paint is to increase the film thickness, so as to play a more effective shielding role. At the same time, the intermediate paint should be able to play a good combination with the primer and topcoat.

For machine tools, automobiles, etc., the middle layer should also make the surface smooth, which is conducive to topcoat coating.

It is made by dispersion of ethyl silicate hydrolysate, zinc powder, anti-rust pigments, solvents and additives. The main features are cathodic protection and excellent anti-corrosion performance. The paint film is tough, corrosion-resistant, solvent-resistant, and has excellent performance.

Good temperature resistance, up to 400 °C. Excellent welding performance and mechanical cutting performance. The main use is mainly used for anti-corrosion of bridges, ships, petrochemical facilities, steel structures, etc., and can also be used as a heat-resistant anti-corrosion primer.

If there are no special requirements for the thickness of the paint film, it is also possible to apply the topcoat directly. The more mature supporting topcoats from low to high include epoxy topcoat and acrylic topcoat, polyurethane topcoat, polysiloxane topcoat and fluorocarbon topcoat. Please choose the type of topcoat according to the owner's requirements and the actual use environment.

Epoxy zinc-rich primer.

It is a commonly used primer for industrial corrosion protection with epoxy primer, and there are still many differences between the two in application.

Composition differences:

Epoxy zinc-rich primer.

to epoxy resins.

Zinc powder is the main raw material, of which zinc powder is the main one of its characteristics, and has strong anti-rust performance.

Epoxy primer is mainly epoxy resin and anti-rust pigment, and anti-rust is worse than zinc-rich primer.

Rust prevention mechanism difference:

Zinc powder in epoxy zinc-rich primers has cathodic protection.

Effect, electrochemical anti-corrosion, stronger anti-rust performance.

Epoxy primer is mainly used to achieve anti-rust effect by shielding pigments.

Differences in function types:

Epoxy zinc-rich primer is mainly distinguished by the content of zinc powder, the zinc content is different, and the anti-corrosion performance is also different, generally in %.

Differences in application areas:

Epoxy zinc-rich primer is mainly used in harsh corrosive environments, such as industrial, marine, coastal, etc., and is used in large-scale projects such as bridges, steel structures, buildings, machinery, etc., and is widely used in long-term protection for more than 15 years.

Epoxy primers are mainly used in general to moderate corrosive environments, and a small number can be used in harsh corrosive environments, but they have a wider range of applications and can be used in all kinds of anti-corrosion coatings.

Differences in supporting systems:

Epoxy zinc-rich primer is generally a three-layer structure: epoxy zinc-rich primer + epoxy micaceous iron intermediate paint + fluorocarbon paint.

Acrylic polyurethane topcoat.

Epoxy primer is generally a two-layer structure: epoxy primer + fluorocarbon paint, acrylic polyurethane paint, epoxy topcoat.

Summary. No matter how good the zinc-rich primer is, it must have a perfect match and a suitable construction method to better achieve the effect of long-term anti-corrosion. Usually we will choose the way of intermediate paint + top coat.

Intermediate paint has strong adhesion, play a transitional role, because most of the topcoat has a certain acidity, acid and zinc will react to form products will lead to poor adhesion between layers, so it should be avoided zinc-rich primer and anti-corrosion topcoat direct use, adding an intermediate paint can achieve better results. The topcoat is the key to the overall coating protection, and the requirements for the topcoat must ensure a series of properties such as weather resistance, decoration, and solvent resistance.

Each topcoat has its own unique advantages, and it is only by combining the coating application and environmental requirements that it is possible to determine which topcoat is more appropriate. Only after a comprehensive analysis can we select a reasonable coating trembling wheel product to sell and support the system.

Hello, I'm glad to answer for you, for you to find the result, yes, Xintan general stove rock, epoxy zinc-rich primer and topcoat can be mixed, but the mixing of different colors of primer and topcoat may affect the final coating effect and color. Therefore, it is recommended that you test before mixing to ensure that the coating effect meets the requirements. At the same time, it should be noted that when mixing, it should be mixed according to the correct proportion, to avoid the coating problems caused by improper proportioning, I hope mine is helpful to you, and I wish you a <>happy life

Epoxy zinc-rich primer. It is widely used in containers or ships. This paint adheres very well and is not easily scratched. Because of the addition of zinc powder, the paint has a very good conductive effect.

This kind of paint can be used in factories because this paint is not easily corroded by chemical products and is generally not used in ordinary home decoration. Let's take a look at what an epoxy zinc-rich primer is.

1. What is epoxy zinc-rich primer?

1. There are many components of this paint, namely ethyl silicate as raw material, thickener, epoxy resin, zinc powder, filler, additives and solvents as auxiliary materials, and epoxy zinc-rich primer belongs to special coatings. In general, it is a metal primer, steel pipe, storage tank, steel structure, container material, which means that epoxy zinc-rich primer has its own special purpose, and epoxy zinc-rich primer is required for protective coating. Epoxy zinc-rich primers are industrial primers that we may rarely use when decorating our homes.

2. This kind of paint may not be as gorgeous as we imagined, because its main purpose is to protect metal materials, so its color is relatively simple, and the common one is black gray, that is, the color of steel. This color is so that it will not look too eye-catching in the process of painting, which is in line with the calm characteristics of heavy industry. Features of epoxy zinc-rich primer:

Naturally, it dries quickly, has strong adhesion and has an obvious anti-corrosion effect, so it can protect these metal objects well. The important thing is that the epoxy zinc-rich primer is rich in zinc, so the cathodic protection and water resistance are excellent.

3. Since the epoxy zinc-rich primer contains certain chemical components, during the painting process, it is recommended that the painting workers wear masks to work, which can prevent breathing a lot of chemical gases. During the painting process, it is necessary to keep the surface of the painted object clean and dry, without any oil stains and rust, so as not to affect the painting effect of epoxy zinc-rich primer; Epoxy zinc-rich primer must be used up within 6 hours after opening, after all, there is a possibility of oxidation in contact with air; In the process of painting, it is only necessary to apply evenly, but when opening the epoxy zinc-rich primer, be sure to stir the primer to avoid precipitation.

2. Precautions for the use of epoxy zinc-rich paint.

1. Diluent and dilution ratio: special thinner for inorganic zinc-rich antirust primer 35.

2. Surface treatment: The steel surface must be rusted by a grinder or sandblasted to reach the Swedish standard level of rust removal.

4. Recommended number of coating channels: 2 3 channels, in construction, the use of portable electric mixer to fully stir component A (slurry), should be used while stirring while construction.

5. The product should be stored in a cool and ventilated place to prevent direct sunlight, and isolate the fire source, away from the heat source in the warehouse.

6. When the product is transported, it should be protected from rain and sunlight to avoid collision, and should comply with the relevant regulations of the transportation department.
