Ultra-Sol® 200S

Small Particle Colloidal Silica Slurry

Ultra-Sol 200S is a high-purity colloidal silica slurry in a specially formulated alkaline dispersion. This unique slurry also contains Eminess’ proprietary non-drying technology that is proven to reduce problems associated with colloidal silica drying, caking, or crystallizing on exposed surfaces. The small particle size of the 200S is designed for the critical polishing of precisionOpto-Electronic materials such as Silicon, Gallium Arsenide, Indium Phosphide, Germanium, and other IR materials. The combination of the small colloidal silica particles with the proprietary chemistry technology produces exceptionally low surface finishes in both pad and pitch processes. Ultra-Sol 200S performs well in slurry recirculation systems due to the robustness of the particle, and its unique chemistry make it easy to suspend and handle.

Handling Instructions

This material is a safe, aqueous based slurry. To avoid skin or eye irritation, however, handlers should use appropriate personal protective equipment including: rubber gloves, protective clothing, and eye protection. Follow all MSDS, Safety Data Sheet, and label precautions when handling this slurry. Also follow all appropriate industrial safety and hygiene practices when handling or using this product.

This slurry is designed as a ready to use product directly from the container. If the slurry is to be used in a diluted form, Eminess recommends using only high-quality deionized water (>18 M ohm) for the dilution. The product should be mixed periodically (10 to 20 minutes per day) by recirculation or mechanical stirring. Mild agitation will keep the particles uniformly suspended. To avoid possible scratching issues, storage and re-use of on-site diluted slurry is not recommended without proper mixing and filtration.

Due to the unique formulation of this slurry, it is recommended that the user not adjust the pH. If a different pH is required, please contact your Eminess Applications Engineer for assistance with your specific process need.

Storage

It is recommended that products be stored up to the expiration date at temperatures between 4°C and 33°C (40°F and 90°F). Products can be stored if kept above freezing (0°C or 32°F), and kept below 38°C (100°F) if prolonged exposure at temperatures at either extreme are avoided. Storage outside of the recommended conditions may result in irreversible product damage. In the event of exposure outside of the recommended conditions, please contact your Eminess representative for recommendations. In all cases the products should be allowed to return to room temperature prior to use.

Disposal

Dispose of in accordance with all applicable national and local regulations.
