Abrasives

The colloidal silicas are used for chemical finishing. Water-insoluble solid silica exists in colloidal distribution in water based solution.

The products stand out due to the following characteristics:

• fine-distributed, colloidal distributed condition in the nanometer range
• high purity, to a large extend free of alkali and electrolytes
• transfer from un-cross-linked sol to a sterically cross-linked gel-condition

Additional to colloidal silicas we also provide aluminium oxide based products and titanium dioxide based products.
