Nalco™ 2358

Colloidal Silica for Stock Removal on Silicon

Nalco 2358 is a colloidal silica polishing slurry specifically formulated as a next generation replacement to the Nalco 2350. It contains lower metals than 2350, and typically yields a 10-15% higher removal rate.This is espcially effective on silicon surfaces due to temperature sensitive amine which activates at 40 degrees Celsius.

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

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.

Disposal

Dispose of in accordance with all applicable local regulations.
