Colloidal Silica / Alumina Suspensions

Used for final polishing, colloidal suspensions are mixtures of abrasive particles dispersed throughout a chemically aggressive liquid carrier. This combination provides a chemical-mechanical polishing action, resulting in deformation-free surfaces.

0.04µm Purple Colloidal Silica

Closer View

A non-stick, rinsable colloidal silica suspension with a pH of 10.47. Excellent for final polishing of all materials with the added benefit of being easy to clean from samples, polishing cloths and machines. Product does not harden and clog the dispenser or drop particles onto cloths when dispensing. Purple color aids in identifying/differentiating from other colloidal products.
