Tunnel boring machines (TBMs) work in harsh underground environments: muddy slurry, abrasive rock debris, acidic underground soil, continuous water seepage cause rapid abrasion and rust on cutter head, shield body, screw conveyor and structural parts. Conventional single paint peels within several months, increasing maintenance downtime.

FLDC launches one-stop full-set coating system specially customized for entire TBM equipment, covering cutter head, shield housing, conveyor, hydraulic components and external steel frame.

Matched coating system:

1. Modified Epoxy Zinc-Rich Primer: Anti-rust base for all steel parts
2. Epoxy Abrasion-Resistant Thick-Film Intermediate Coat: Anti-slurry abrasion core layer
3. OM-5 High Temperature Anti-Corrosion Topcoat: Resist underground chemical & hot soil
4. Epoxy Repair Putty: Fix equipment surface wear pits during maintenance Core Advantages: ✅ Complete matching system for all TBM components ✅ Extreme wear resistance against rock slurry impact ✅ Resist acid underground water & corrosive soil medium ✅ Strong adhesion under frequent vibration of tunneling ✅ Short construction cycle, reduce machine idle time
