Anti-rust paint is not uncommon. All kinds of metals and steel structures we encounter in daily life require anti-rust construction. It can prevent rust from metal and steel structures and allow our metal household products to be used for longer. So what are the tips for purchasing anti-rust paint?
anti-rust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion by the atmosphere, seawater, etc. It is mainly divided into two categories: physical and chemical anti-rust paint. The former relies on the proper cooperation of pigments and paints to form a dense paint film to prevent the invasion of corrosive substances, such as iron red , aluminum powder , graphite anti-rust paint, etc.; the latter relies on the chemical anti-rust pigments, such as red dan , zinc yellow anti-rust paint, etc. Used for rust prevention of metals such as bridges, ships, and pipelines.
Anti-rust paint (industrial water paint)
So, which type of common metal anti-rust paint is better?
1. The longer ordinary anti-rust paint is iron red anti-rust paint . Basically, what we see at home are iron red anti-rust paint or reddish anti-rust paint. Both of these paints are relatively cheap and have general water and weather resistance. Theoretically, the service life is within 1 year. However, for some small parts at home, such as triangle iron, railings, etc., it will be fine for several years to use. It is also cheap and can be constructed separately, which is relatively cost-effective. Of course, this is limited to basic anti-rust requirements, and high requirements are inappropriate. Neither iron red nor red rust anti-rust paint can be adjusted, and the color is relatively single. If there are color requirements, you can use alkyd paint below.
2. Alkyd paint can be used for some high anticorrosion requirements, such as street lights, guardrails, etc. Alkyd paint can be color-touched and can meet the color needs of different occasions. Alkyd paints include alkyd primer, blending paint , alkyd magnet paint . Generally speaking, alkyd primer, blending paint or other alkyd topcoats are enough. The color is better, and the water resistance and weather resistance are better than the iron red and red pills on it, which is one level higher. The alkyd magnetic paint among alkyds is of the same grade as acrylic paint , and the price and performance are basically similar.
3. For ordinary users, ordinary paint with a better corrosion resistance environment is outdoor acrylic paint. Whether it is color, weather resistance, water resistance, and rust resistance, they are better than the two mentioned above. In theory, they can be used for 5-8 years. Of course, the price is quite expensive, and if the anti-corrosion requirements are high, it is also a better choice.

anti-rust paint purchase tips
1, environmentally friendly
When we purchase anti-rust paint, we first need to look at its environmentally friendly performance. Try to choose anti-rust paint with low VOC content. Generally, the lower the VOC content of anti-rust paint, the better its environmental performance.
2. Smell
Excellent quality and environmentally friendly anti-rust paint should be water-based and non-toxic and odorless. We can smell the odor of anti-rust paint when purchasing. If you smell a irritating smell or industrial flavor, the environmental protection and quality of this anti-rust paint are usually poor and cannot be selected.
3, film forming
Usually after the anti-rust paint is placed for a period of time, the anti-rust paint with excellent quality usually forms a thick and elastic oxide film on the surface, which is not easy to crack. The poor-quality anti-rust paint surface film is not only thin but also fragile, but also has a spicy smell of kelp.
