Global green hydrogen capacity expands rapidly in 2026. Alkaline water electrolyzers rely on metal frames and internal runners, which are continuously eroded by high-concentration alkaline electrolyte. Ordinary epoxy coating will swell and peel within 2–3 years, polluting hydrogen purity and increasing equipment replacement costs.

FLDC independently developed high-purity PTFE fluoropolymer coating specially for hydrogen electrolyzer inner walls and metal components. Ultra-dense fluorine film blocks alkaline liquid penetration without impurity precipitation, guaranteeing qualified hydrogen purity.

Complete electrolyzer coating matching system:

1. Modified epoxy bonding primer (special for metal & PTFE interlayer adhesion)
2. Middle fluorine transition layer to eliminate film delamination risk
3. High-purity PTFE top lining resistant to strong alkali medium Core Advantages: ✅ Resist 30%+ strong alkaline electrolyte long-term soaking without blistering ✅ Zero impurity dissolution, keep hydrogen production purity up to standard ✅ Stable under continuous 80℃ electrolysis working temperature ✅ Smooth surface easy to clean residual electrolyte sediment ✅ Pass hydrogen energy equipment medium aging certification Our PTFE electrolyzer coating has been exported to green hydrogen manufacturers in Europe, Southeast Asia and Australia.
