Powder Coating for Valves and Water Infrastructure

Valves, pumps and water infrastructure demand coatings that stop corrosion while keeping water safe. Epoxy-based powder systems provide a dense, chemical-resistant film built for drinking water, sewage and heavy-duty valve service.

Recommended Coating Systems

• Fusion-bonded epoxy (FBE) for buried and wet service
• Epoxy for valve bodies, pumps and interior parts
• WRAS / ACS compliant formulations for potable water contact

Key Performance Properties

• Outstanding adhesion and corrosion protection
• Chemical and abrasion resistance in aggressive media
• Water-safety compliance options with documentation
• Good edge and pinhole coverage

Typical Specifications

• Film thickness: 80–150 µm (typical)
• Cure: 180–200°C / 10–20 min
• Gloss: semi-gloss to high-gloss
• Standards: WRAS, ACS, ISO salt spray on request

Application Notes

• Blast and pretreat to remove oil, rust and scale
• Mask sealing faces and threaded connections
• Control cure on castings to avoid outgassing

Frequently Asked Questions

Can you certify coatings for drinking water contact?

Yes — we supply WRAS- and ACS-compliant epoxy formulations with the supporting documentation.

What film thickness is best for buried valves?

100–150 µm with fusion-bonded epoxy gives strong corrosion protection for buried service.
