Pre-film agent FCA5101
FCA5101 is a high-efficiency prefilming agent engineered specifically for the critical pre-operational prefilming stage of industrial recirculating water systems. Applied after successful chemical cleaning, it rapidly forms a dense, uniform composite protective film on carbon steel, copper alloys, stainless steel, and other metal surfaces through chelation with divalent metal ions (e.g., Ca2+, Mg2+) in water. This film effectively isolates corrosive media, significantly enhancing the system’s initial corrosion resistance. As a foundational step in water treatment protocols, FCA5101 ensures seamless transition to routine water stabilization, safeguarding long-term operational reliability across power, petrochemical, and metallurgical cooling systems.

Product Features
- Precision Film Formation: Chelates selectively with divalent ions to build a highly adherent, dense composite film within 48 hours, optimizing surface passivation.
- Multi-Metal Compatibility: Effective on carbon steel, copper alloys, stainless steel, and galvanized pipes; mitigates galvanic corrosion risks in heterogeneous systems.
- Seamless Process Integration: Works synergistically with FCA5102; post-prefilming water replacement enables smooth transition to routine treatment without process interruption.
- Operational Efficiency: Dosage 160–500 mg/L; excellent water solubility; forms film under ambient-temperature circulation—no heating or special equipment required.
- Eco-Compliant Workflow: Post-prefilming replacement to total phosphorus ≤20.0 mg/L (as PO43-) ensures environmental compliance; low-toxicity formula supports safe handling.
- Broad Compatibility: Harmonizes with mainstream corrosion/scale inhibitor programs without interference.

Instructions for Use
- Application Stage: Prefilming phase after chemical cleaning and before system commissioning.
- Procedure:
- Use in conjunction with FCA5102; dose at 160–500 mg/L based on system water volume.
- Circulate at ambient temperature for ≥48 hours to ensure uniform film formation.
- After prefilming, replace system water until total phosphorus ≤20.0 mg/L (as PO43-), then proceed to routine water treatment.
