FCA5500 Prefilming Agent
FCA5500 is a high-efficiency liquid prefilming agent produced exclusively for the critical pre-operational prefilming stage following chemical cleaning of industrial recirculating cooling water systems. Applied after successful cleaning and prior to system commissioning, it rapidly forms a dense, uniform composite protective film on carbon steel, copper alloys, stainless steel, and other metallic surfaces through targeted chelation with divalent metal ions (e.g., Ca2+, Mg2+) in water. This film effectively isolates corrosive media, significantly enhancing initial corrosion resistance. As a pivotal bridge between cleaning and routine water treatment, FCA5500 establishes a robust foundation for long-term system reliability and is widely deployed across power, petrochemical, metallurgical, and HVAC industries to ensure safe, efficient equipment startup and extended service life.
FCA5500 Prefilming Agent
FCA5500 can be used for pre-filming treatment after chemical cleaning of circulating cooling water systems.
Product Features
- This product is mainly used for pre-filming treatment of water systems during normal operation. When added to circulating water, it chelates with divalent metal ions in the water to form a thin and dense anti-corrosion film, protecting metal equipment or pipelines. This pre-filming agent can be used in conjunction with any water quality stabilizer.

Instructions for Use
- This product is mainly used for pre-filming treatment of water systems during normal operation. When added to circulating water, it chelates with divalent metal ions in the water to form a thin and dense anti-corrosion film, protecting metal equipment or pipelines. This pre-filming agent can be used in conjunction with any water quality stabilizer. A good pre-filming effect can generally be obtained by adding a concentration of 300-600 ppm and running in a cold state for more than 48 hours.
Packing and Storage
25 kg plastic drums. Store sealed in a cool, dry, well-ventilated area, protected from light and moisture.
Shelf Life
6 months.
