Nalco™ 2371

Standard Colloidal Silica

Nalco 2371 is a colloidal silica polishing slurry specifically designed to meet the requirements of recirculated stock removal systems and low sodium levels. The level of sodium ion impurities in this slurry has been minimized through additional manufacturing procedures. Nalco 2371 routinely produces silicon stock removal rates that are 30 to 50% higher than conventional stock removal products, and is considered the most effective Nalco slurry available. Efficiency of use is achieved with 15:1 to 20:1 dilutions for stock removal.

Handling Instructions

Storage tanks and distribution piping should be constructed of engineering plastic, such as polyethylene, polypropylene, or PTFE. Materials such as aluminum, copper, brass, and PVC should be avoided. Avoid leaving slurry containers open for extended periods of time. Leaving containers open may result in drying which can cause wafer scratching.


Storage outside of the recommended conditions may result in irreversible product degradation. Products can be stored up to the expiration date between the temperatures range of 0°C - 45°C (32°F - 113°F). Avoid prolonged exposure at temperatures at either extreme. In all cases the products should be allowed to return to a room temperature prior to use. All shipments include temperature indicators to monitor shipping conditions.


Dispose of in accordance with all applicable local regulations.
