Solution for preventing biological attachment on bridge piers
Biofouling Hazards on Bridges
Pier columns, as an important component supporting bridges, are often submerged in water and are susceptible to erosion by aquatic organisms such as algae and mollusks. The attachment and proliferation of these organisms on bridge structures significantly accelerate the corrosion process of the pier surface, releasing chemical substances, particularly acidic ones, which directly act on the pier material, weakening its structural strength.




Additionally, the formation of biofilms alters the physical characteristics of the bridge, increasing surface roughness, leading to increased flow resistance, and consequently raising the dynamic water pressure on the bridge.
Long-term exposure to this enhanced dynamic water pressure accelerates fatigue damage to bridge materials, threatening the structural stability of the bridge, affecting overall safety performance, and reducing the service life of the bridge. Therefore, applying coatings with anti-fouling and self-cleaning properties to bridge piers is crucial for protection.
Biomimetic Self-Cleaning Antifouling Coating
Superior Marine Biofouling Resistance
Deqian Xincai's biomimetic self-cleaning antifouling coating enhances the flexibility and wear resistance of the coating significantly by nanomodifying organic silicon resin and optimizing the overall formula design, based on low-surface-energy interfaces. It also employs unique antibacterial technology to confer excellent antifouling performance to the coating.

Nontoxic and Environmentally Friendly
Free from DDT and eight major heavy metals, the coating does not hydrolyze to release harmful substances that pollute the ocean, with a zero mortality rate in acute toxicity tests on fish.
Good Mechanical Properties
The biomimetic self-cleaning antifouling coating material withstands underwater robot cleaning; high-pressure water washing; sand abrasion; wear-resistant flexibility: resistant to repeated bending, cable winding, and unwinding...



Excellent Construction and Substrate Adhesion
- Convenient construction, rapid curing at room temperature, high painting efficiency.
- Can be sprayed onto any curved, sloping, or vertical surfaces.
- Dense coating without seams, good appearance.
- Strong adhesion, quickly bonds to steel, epoxy anticorrosion coating, polyurethane, plastic, PVC, and concrete surfaces.
