What is the difference between oily and water based epoxy zinc rich primers?

1. Film-forming substances.

While water-based with oil-based epoxy zinc-rich primers.

The main film-forming substances are epoxy resins.

But one is water-based epoxy and the other is oil-based.

2. Storage temperature.

Water-based epoxy zinc-rich primers can be stored at a temperature of 0-40, while oil-based epoxy zinc-rich primers can be stored at a temperature of -5 or even -10.

3. Solvent content.

The content of organic solvent in water-based epoxy zinc-rich primer is very small, generally about 1 2%; The oily epoxy zinc-rich primer, the variety with high solid content, is also more than 20%, and the solvent content of ordinary epoxy zinc-rich primer is more than 50%. The damage of organic solvents to the environment and the toxicity of the human body have been paid attention to by all sectors of society, and the construction of oil-based paints has been banned in some areas.

4. Health effects.

During the construction of water-based epoxy zinc-rich primer, the water volatilized is not combustible, non-combustible, and non-dangerous. During the construction of oil-based coatings, volatilized include: toluene and xylene.

Esters, ketones, etc., all have flammable and explosive characteristics. It has a certain impact on human health.

5. Construction methods.

When spraying a higher film thickness at one time, the anti-sag performance of water-based epoxy zinc-rich primer is poor; When the flow rate of the water-based epoxy zinc-rich primer changes sharply in the conveying pipeline, the dispersed particles are compressed into solid particles, which is easy to produce paint diseases such as pitting.

Oil-based paint, also known as grease paint. A kind of coating with dry oil as the main film-forming substance, mainly including clear oil, thick paint, oil-based blending paint, oil-based anti-rust paint and putty, putty, etc. The oils used are mainly tung oil, linseed oil, catalpa oil, soybean oil, sunflower oil, fish oil, etc., which are characterized by easy production, low cost, good brushability, flexible coating film and good permeability.

The disadvantage is that it dries slowly and the physical and chemical properties of the coating film are poor, and most of them have been replaced by synthetic resin paints with excellent performance.

Water-based paint is a paint that uses water as a solvent and can be diluted with water. Its waterproof performance is poor.

Hongdan paint and epoxy zinc-rich primer are both antirust primer varieties with good antirust performance, what is the difference between the two and which one has better performance? The following (crown) coatings will give you an introduction to their differences:

1. There are two main types of red dan anti-rust paint: alkyd red dan paint and epoxy red dan anti-rust paint. Alkyd red dan antirust paint is mainly used for steel coated with alkyd paint and amino paint that have rusted, and the renovation project after simple rust removal is matched with alkyd magnetic paint. Red pill is highly toxic and has been banned in many countries.

The characteristics of red dan paint are that it has good adaptability to the surface, and the lower surface treatment can also achieve a better anti-corrosion and anti-rust effect. Epoxy Hongdan antirust paint is mainly used for steel coated with epoxy primer and polyurethane primer and has taken effect, and is used in the renovation project after simple rust removal, supporting all kinds of two-component topcoats.

2. Epoxy zinc-rich primer is used for steel surfaces that have been sandblasted to grade or power derust to ST3 grade, and used as an anti-corrosion and anti-rust primer. The supporting topcoat is polyurethane topcoat, acrylic polyurethane topcoat, fluorocarbon topcoat, epoxy topcoat, etc. It is much better than ordinary anti-rust paint in terms of salt spray resistance, anti-rust effect and paint film characteristics.

From the above comparison, it can be seen that if the rust removal effect is very good, it is recommended to use epoxy zinc-rich primer, if the rust removal effect is poor, or the rust removal is difficult, Hongdan paint can be selected according to the type of original paint. In addition, the red dan paint is more toxic, if environmental protection is considered, you can use epoxy iron red primer instead of red dan paint, and thicken the coating.

These two paints are not used for the same purpose.

The role is different. Anti-rust paint is mainly used to prevent rust.

Zinc-containing primers are more stable.

Inorganic zinc-rich primer andEpoxy zinc-rich primerThe main differences are the different raw materials, different characteristics, and different uses, as follows:

First, the ingredients and raw materials are different

1. Inorganic zinc-rich primer: inorganic zinc-rich paint is mainly divided into water-based inorganic zinc-rich paint and alcohol-soluble inorganic zinc-rich paint. The lacquer is made of alkali metal.
