LNG storage tanks work under extreme operating conditions: huge temperature difference between cryogenic inner medium and ambient external environment. Tank outer steel shells bear alternating cold‑heat impact, ultraviolet aging and coastal salt‑fog erosion. Conventional anti‑rust paint will crack under large temperature fluctuation and lose protective performance.

FLDC three‑layer matched anti‑corrosion coating system for LNG tank outer steel shell:

1. Modified epoxy zinc‑rich primer: Stable adhesion under frequent temperature change
2. Epoxy micaceous iron oxide high‑solid intermediate coat: Improve barrier and stress‑buffering performance
3. National‑standard fluorocarbon topcoat: Long‑term weathering, anti‑chalking and color retention

Core Advantages:
✅ Adapt huge temperature difference between tank inner cryogenic medium and outside atmosphere
✅ Resist coastal heavy salt‑fog and strong UV radiation
✅ Flexible film structure absorb thermal‑stress without cracking
✅ 18+‑year outdoor service life for LNG plant outer shell
✅ Compliant with international liquefied‑gas facility coating standards
