Anti-corrosion paints for C4 and C5

To effectively protect surfaces from rust and its destructive effects, it's important to use specialized products optimized for the specific conditions and corrosiveness class of the environment they will be used in. This category includes C4 and C5 anti-corrosion paints – suitable for spray application as well as traditional application methods using painting accessories. Most of our products can be ordered in any color, choosing from a wide range of RAL shades.

Where to use C4 anti-corrosion protection?

We offer anti-corrosion paints with a corrosion class of C4. They are used on outdoor steel structures in environments characterized by significant air pollution. Choose these products if the risk of corrosion is primarily related to:

• proximity to the sea, which causes atmospheric precipitation to contain a large amount of salt that negatively affects metal surfaces,
• high air humidity,
• air dust resulting from the presence of industrial facilities emitting harmful dust,
• the content of sulfur oxide in the air – it is the cause of so-called acid rain, which has a particularly negative effect on elements made of carbon steel, nickel, zinc, and copper,
• frequent changes in temperature and sunlight – moisture combined with extreme weather conditions favors the development of rust.

Corrosion class C4 applies primarily to coastal and industrial areas, but also to swimming pool hall structures.

C5 anti-corrosion protection – application

In chemically aggressive environments, high-performance metal surface protection is essential – for this purpose, C5 anti-corrosion paint . A C5 corrosion class means that steel structures are susceptible to airborne gases such as sulfur dioxide, hydrogen chloride, hydrogen sulfide, ammonia, as well as sulfuric acid vapors and high inorganic salt content.

C4 and C5 anti-corrosion paints – check available preparations

We offer direct-to-rust elastomers that can be applied without sanding or prior surface preparation. They create a waterproof coating with anti-corrosion properties. They are suitable for steel structures located in highly aggressive environments. We also offer polyurethane paints for metal . They also work well on wood, concrete, and steel. Use them if you want to protect the painted surface from atmospheric factors and chemicals. They create a smooth, scratch-resistant layer. High adhesion and efficiency are the key advantages of our solutions.

If you want to protect metal surfaces – including galvanized ones – against the destructive effects of gases and acids, choose epoxy metal paints .

Choose anti-corrosion paints for demanding areas in the C4 and C5 classes

Drawing on years of experience, we've compiled the best anti-corrosion paints for aggressive and industrial environments. When planning to paint surfaces with a C5 corrosion class, the coating thickness must be precisely selected – only then can you guarantee effective rust protection. Our consultants will be happy to help you purchase the right products, providing substantive support and verifying the specific requirements of each client.
