Infrastructure Trends: Designing for Longer Service Life
How low-VOC, high-solids stacks are helping owners extend repaint cycles and reduce total lifecycle cost.
Key Takeaways
- Zinc/epoxy/PU stacks remain the benchmark for steel bridges
- Surface prep and DFT control drive real-world performance
- Low-VOC options can meet permit limits without sacrificing durability
Specification Kit
Color-Coded Data Sheets and Inspection Steps
Every family carries a matching swatch, label, and TDS/SDS bundle to keep purchasers, applicators, and inspectors synchronized.
- Surface prep and DFT targets for QA/QC teams
- Mixing, pot life, and cure windows by product
- Custom formulation pathway for unique substrates
Fast Actions
What’s Changing
Emission Standards Tighten
Owners are requesting water-based or high-solids options that still deliver long-term corrosion defense.
Inspection Rigor Increases
DFT, adhesion, and cure verification are expected at each stage; TDS/SDS must align with inspection plans.
Lifecycle Cost Focus
Longer repaint cycles reduce closures and labor, making higher-performance stacks more attractive.
Training & Safety
Applicator readiness—PPE, ventilation, and mixing—is critical to quality and compliance.
LPTHC Perspective
- Match stack design to environment: immersion, splash zone, or atmospheric exposure.
- Use TDS to enforce prep, DFT, and cure windows to reduce rework.
- Consider low-VOC options early to avoid permit delays.
- Document everything: inspection checkpoints, SDS, and turnover packages for owners.
