Aerogel, commonly known as "freeze smoke", is a special material made by extracting the water from silica gel and then replacing the water with a gas (such as carbon dioxide, etc.). This substance has excellent insulating properties while adsorbing contaminants such as crude oil. There are a large number of tiny pores inside the airgel. The typical pore size is between 1 and 10 microns, and the porosity is as high as more than 80%, which makes it a material with a nanoscale porous structure.
The process of preparing thick coats of epoxy-polyethylene resin for heavy-duty anti-corrosion coatings is relatively simple. First, accurately weigh the bisphenol epoxy resin and diluent into a mixing tank and stir thoroughly to completely dissolve it into a uniform and transparent resin liquid. Next, part of the resin liquid is taken out and mixed together with the pigments and fillers, and the mixture is then ground through a three-roller mill to the desired particle size. Finally, add the remaining resin liquid, stir evenly, then filter and package.
The paint is applied using air spraying. During this process, an air pump needs to be used to mix the compressed air with the paint, usually the compression ratio is 1:45, and the pressure of the atomized air is between 0.4~0.5MPa. On vertical surfaces, a coating film with a thickness of up to 10 mm can be applied, and this coating film can usually be cured at room temperature or low temperature.

This thick-coat heavy-duty anti-corrosion coating of epoxy-polyethylene resin has good mechanical properties, especially at low temperatures. It also performs well in extremely harsh environments and has excellent anti-corrosion properties. In addition, the coating film of this coating cures at room temperature or low temperature and can maintain toughness and softness over a wide temperature range. It is suitable for various application fields such as component equipment and marine buildings.
In summary, epoxy-polyethylene resin thick-coat heavy-duty anti-corrosion coatings represent an innovative protective solution that provides reliable corrosion protection for a variety of engineering projects and is expected to continue to play an important role in the future. As technology continues to advance, we can expect more new anti-corrosion coatings to emerge to address changing engineering and environmental needs.
