Crystal Jewelry Method – Advanced Anti-Corrosion & Protective Coating Technology from Japan

1. What is Crystal Jewelry Method?

The Crystal Jewelry Method is an advanced protective coating technique developed in Japan, designed for steel, rubber, and concrete structures such as bridges, overpasses, and infrastructure exposed to harsh environments. The method employs a special transparent silicone-based clear resin that forms a durable, waterproof, corrosion-resistant layer, helping to extend service life and improve long-term maintenance efficiency. hmplan.co.jp+2株式会社サンクリエイト+2

The method is registered under Japanese patents (Patent No. 6954570) and has been recognized in public infrastructure technology catalogs (NETIS CB-220023-A). hmplan.co.jp+1

2. Key Technical Features & Mechanisms

• High corrosion resistance & salt/chemical durability: The silicone-based clear resin resists salt spray, de-icing salts, and chemical agents — ideal for marine/coastal, cold-weather, or industrial environments. 株式会社サンクリエイト+1

• Transparent coating for easy inspection: Because the coating is transparent, structural surfaces remain visible, allowing visual inspection and early detection of any damage or deterioration. nakaishoko.co.jp+1

• Fluorescent verification under black light: During application, each coating layer fluoresces distinctively under ultraviolet (black light), enabling clear verification of coverage and eliminating missed spots (a common problem when using clear coatings). hmplan.co.jp+1

• One-component system: Simplifies application, reduces human error risk, and accelerates construction schedule. 株式会社サンクリエイト+1

• Multi-substrate compatibility: Can be applied over steel, rubber bearings, or concrete surfaces — including old or corroded areas, enhancement coatings, and over existing protective coatings. hmplan.co.jp+1

3. Main Benefits & Advantages

4. Typical Use Cases & Applications

The Crystal Jewelry Method is ideal for:

• Bridges and overpasses — girders, end plates, bearing seats, support columns

• Marine/coastal infrastructure exposed to salt spray (ports, piers, sea-facing roads)

• Concrete structures subject to chloride penetration, de-icing salts, or chemical exposure

• Structures requiring minimal visual impact (transparent coating — aesthetic preservation)

• Rehabilitation / repainting projects — over existing coatings or partially deteriorated surfaces

5. Why This Is Relevant for Vietnam

Vietnam has many coastal and riverine structures, tropical climate with high humidity and salt air near coastlines, heavy traffic load on bridges and overpasses, and growing demand for infrastructure longevity and low maintenance cost. The Crystal Jewelry Method offers a cost-effective, durable, low-maintenance anti-corrosion solution that can significantly improve the lifespan of bridges, piers, and other key structures, while facilitating regular inspections with minimal disruption.

6. Conclusion

The Crystal Jewelry Method represents a Japanese-developed, advanced, and practical technology for protecting critical infrastructure against corrosion, environmental damage, and long-term deterioration — all while enabling easy inspection and reducing life-cycle costs.

For Vietnamese infrastructure projects where durability, maintenance cost, and environmental harshness are concerns, this solution offers clear technical and economic advantages.
