Brush-On Simplicity, No Pro Equipment Needed: Zinc-Rich Coatings Make Heavy-Duty Corrosion Protection As Easy As Painting
Dec 11, 2025
For a long time, providing long-term corrosion protection for heavy industrial facilities, steel bridges, offshore platforms, and similar structures has been the domain of professional coating teams, relying on complex surface preparation and expensive spray equipment. However, the popularization of a new type of high-performance zinc-rich coating is revolutionizing this field, making heavy-duty corrosion protection as straightforward as ordinary painting.
Product usage scenario cases
We are looking for a cooperative partner to expand our business.
Traditional heavy-duty corrosion protection solutions typically require strictly controlled application environments, skilled workers, and large airless spray equipment to ensure the coating achieves the required zinc content and thickness. But the latest generation of zinc-rich coating products, through advanced resin technology and optimized zinc powder ratios, has significantly improved user-friendliness. These products not only maintain the core cathodic protection function of sacrificial anodes but can also be easily applied using ordinary brushes or rollers, with more forgiving requirements for surface preparation.
This means that maintenance personnel, field engineers, and even workers with basic skills can personally apply professional-grade corrosion protection in confined spaces, corners, or for quick repairs where large equipment cannot be deployed. The application process requires no power-driven equipment, greatly enhancing operational flexibility and safety while also reducing the high costs associated with equipment rental and dispatching specialized teams.
The product is easy to use
HOW TO USE
Before use
A surface roughness of Rz40μm
-75μm (medium roughness in
the ISO8503-1comparison plate)
is the best, and it is best to apply
within 4 hours after jet cleaning
Stir the paint
When using, stir well with an
electric mixer, and add an appr
-opriate amount of purified wat
-er to adjust to the appropriate
construction viscosity.
Brush Paint
The construction environment tempera
-ture is 5-50"C, the relative humidity
of the air is not more than 80%, and the
surface temperature of the steel should
be greater than the dew point of 3°C
Spray Coating
Construction method: Airless spraying
air spraying is recommended, brush
and roller coating are only recommend
-ed for pre-coating, small-area painting
or repair.
As technological advancements continue to lower the barrier to high-performance coatings, "heavy-duty corrosion protection" is gradually transforming from a specialized engineering task into a standard maintenance operation that can be performed anytime, anywhere, opening a new chapter in the long-cycle health management of global assets.
