Metal Surface Anti-corrosion and Self-Cleaning Agent

Metal Surface Anti-corrosion and Self-Cleaning Agent is a specialized surface treatment agent designed for metal building materials, utilizing super-hydrophobic and photocatalytic technologies to address issues of dust adhesion, oxidation, and rusting in outdoor environments. This product enhances the corrosion resistance and self-cleaning capabilities of metal surfaces by forming a superhydrophobic coating and a photocatalytic self-cleaning layer, thereby extending the service life of metal building materials and reducing maintenance costs.

Super-hydrophobic Technology

Principle: Modifies the metal surface with nanoscale materials to create micro-nanostructures, achieving super-hydrophobic effects.

Effect: Effectively reduces the penetration of corrosive agents such as moisture and salt spray, minimizing oxidation and rusting risks for metal building materials.

Photocatalytic Technology

Principle: Introduces photocatalysts (e.g., TiO₂) into the coating, generating free radicals under light exposure to decompose organic pollutants.

Effect: Enables self-cleaning functionality, reducing dirt adhesion and maintaining long-term cleanliness of the metal surface.

Metal Derusting and Protection at Construction Sites

Problem: Rebar and other metals exposed to humid environments are prone to rusting, compromising structural safety.

Solution:

Derusting: Remove loose rust layers from the metal surface through mechanical or high-pressure water blasting.

Protection: Apply the product to form a superhydrophobic + photocatalytic coating, preventing secondary rusting.

Protection of Metal Building Materials

Application Areas: Enclosures, factory roofs, exterior walls, doors, and windows.

Effects:

Superhydrophobicity: Repels rainwater, reducing moisture erosion.

Self-cleaning: Photocatalytically decomposes dirt, lowering manual cleaning frequency.

Long-lasting Protection: The superhydrophobic coating effectively isolates corrosive agents, extending the metal's service life.

Safety and Efficiency: The photocatalytic technology operates without additional manual intervention, leveraging natural light for self-cleaning.

Convenient Application: Suitable for complex metal surfaces via spraying, brushing, or dipping.

Cost-effectiveness: Reduces maintenance frequency and costs, enhancing the overall economy of metal materials.

Project Background: A large-scale construction site faced severe rebar rusting due to prolonged exposure to humid conditions, raising concerns about project delays and structural integrity.

Solution:

Step 1: Remove loose rust layers using high-pressure water or mechanical derusting equipment.

Step 2: Spray Metal Surface Anti-corrosion and Self-Cleaning Agent to form a uniform coating.

Step 3: Allow natural drying or low-temperature curing to ensure strong adhesion between the coating and the metal surface.

With the construction industry's increasing demand for material durability and environmental sustainability, Metal Surface Anti-corrosion and Self-Cleaning Agent holds vast application potential in metal building material protection. Its innovative technology and proven efficacy make it a preferred solution in high-corrosion environments such as marine engineering, bridge construction, and high-rise buildings.
