  • Siliceous composition and its use in papermaking
    Patent number: 8097127
    Abstract: An aqueous polysilicate composition comprising a polysilicate microgel based component in association with particles derived from colloidal polysilicate. The invention also concerns a process for preparing an aqueous polysilicate composition comprising mixing an aqueous colloidal polysilicate with an aqueous phase of a polysilicate microgel. The aqueous polysilicate composition is more effective than colloidal silica and is more stable than a conventional polysilicate microgel.
