Product Description
Special Anti-Corrosion Coating, Hollow Glass Bubble, HN32, Aerospace Adhesives, Thermoplastic
Hollow Glass Bubble Benefits
The use of hollow glass bubbles in anti-corrosion coatings significantly reduces weight, making application easier and decreasing substrate load. This results in transportation and labor cost savings. Additionally, hollow glass bubbles enhance corrosion resistance properties, protecting substrates from damage and reducing corrosion risk.
Applications
- Industrial equipment: Protects tanks, vessels, and pipes from chemical corrosion
- Infrastructure: Shields bridges, highways, and buildings from environmental corrosion
- Marine and offshore structures: Guards ships, oil rigs, and pipelines against harsh marine conditions
