Inhibitor ZP8508

• Mild steel corrosion inhibitor
• Excellent blend of a phosphate and zinc source for treatments

DESCRIPTION AND USE

Inhibitor ZP8508 is a liquid, phosphate/zinc-containing product designed to enhance corrosion protection in mill supply water systems, once through cooling systems and open recirculating systems.

This product contains a blend of phosphate with to develop the optimal combination of inhibitor for mild steel. This product can be fed at a variety of feed rates depending on the application and the water chemistry. The phosphate film formed in these programs provides excellent protection for mild steel.

TREATMENT AND FEEDING REQUIREMENTS

Dosage – The optimal dosage of Inhibitor ZP8508 is a function of the corrosivity of the water to be treated, application conditions and the specific application.

For best performance, this product should be fed continuously. While the typical dosage is 1 to 6 ppm (mg/L) for an once-through application, this product is to be used in accordance with control procedures that GE Betz establishes for a specific application. This product is also extensively used as a phosphate source for programs like Dianodic III and Continuum AEC technologies.

Dilution – Inhibitor ZP8508 may be fed directly from the shipping container or diluted to any convenient strength.

Feed Equipment – Tanks, pumps, piping, and valves should be made of 316 stainless steel or most common plastics. Avoid the use of mild steel and copper alloys.

Monitoring – A photometric procedure can be used to monitor the zinc concentration in the treated water.
