ULTRA-SOL® 500S
Colloidal silica slurry
Broad process application:
ULTRA-SOL® 500S is a non-drying colloidal silica slurry designed for polishing a wide range of precision opto-electronic materials. A staple in any optician’s arsenal, 500S has been an industry standard for over 20 years. The slurry’s trademark blue color is now widely recognized by master opticians throughout the industry.
The ULTRA-SOL® 500S is a high-purity colloidal silica slurry with a specially designed alkaline dispersion. This reduces problems caused by colloidal silica particles drying, caking or crystallizing on exposed surfaces. The end result is superior surface finishes, reduced scratches, along with lowered cleaning costs, material staining, and waste.
ULTRA-SOL® 500S is capable of producing surfaces of less than 5Å RMS in a pad process, and less than 1Å RMS in a pitch process. The 500S performs well in recirculation systems due to the robustness of the primary particle.
