Heavy-duty anti-corrosion paint refers to a type of anti-corrosion paint that can be used in relatively harsh corrosive environments compared to conventional anti-corrosion paint, and has a longer protection period than conventional anti-corrosion paint.

Features of heavy duty paint:

①Can be used under harsh conditions and has a long anti-corrosion life. Heavy-duty anti-corrosion coatings can generally be used for more than 10 years or 15 years in chemical atmospheres and marine environments, even in acid, alkali, salt and solvent media. , and under certain temperature conditions, it can also be used for more than 5 years.

②Thick film is an important symbol of heavy-duty anti-corrosion coatings. The dry film thickness of general anti-corrosion coatings is about 100μm or 150μm, while the dry film thickness of heavy-duty anti-corrosion coatings is above 200μm or 300μm, and 500μm~1000μm, even as high as 2000μm ;m.

Main application areas of heavy duty coatings:

①Emerging marine engineering: offshore facilities, coastal and bay structures, offshore oil platforms;

②Modern transportation: highway guardrails, bridges, boats, containers, trains and railway facilities, automobiles, airport facilities;

③Energy industry: hydraulic equipment, water tanks, petroleum refining equipment, petroleum storage equipment (oil pipes, oil tanks), power transmission and transformation equipment, nuclear power, coal mines;

④Large industrial enterprises: papermaking equipment, medical equipment, food and chemical equipment, inner and outer walls of metal containers, pipelines in chemical, steel, petrochemical plants, storage tanks, mining and smelting, cement plant equipment, ground and wall cement with corrosive media component;

⑤ Municipal facilities: gas pipelines and their facilities (such as gas tanks), natural gas pipelines, drinking water facilities, garbage disposal equipment, etc.

What are the main points of heavy-duty anti-corrosion coating coating control?

①Choose the appropriate heavy-duty anti-corrosion paint, and it must be used together with the bottom, middle and top paints.

②The thickness of the coating should not only exceed the critical thickness, but also reach an appropriate thickness according to different anti-corrosion requirements.

③Requires strict pre-coating treatment and meets the specified surface treatment standards.

④Strict coating construction management.
