Colloidal Silica

This non-crystallising Colloidal Silica is made to be user friendly. It eliminates the problems that are caused by drying or freezing that are associated with other colloidal silica products which are used for chemical/mechanical polishing.

Colloidal silica is a first choice silica dispersion for optimising polishing results such as silicon, fused quartz, fused silica, lithium niobate, YAZ, GGG, alexandrite, sapphire and many others.

Application: Colloidal silica can be used full strength or diluted. Dilution to 1:1 or higher with de-ionised water is recommended. Polyurethane and short nap cloths can be used.
