Unlike most grades of colloidal silica, the silica particles are coated with an aluminum compound that imparts a positive charge. LUDOX® CL Colloidal Silica may be used in various coating applications in which the formulation requires acidic pH or cationic polymers or surfactants. The positively charged particles may be used as surface treatments to paper and fibrous materials. LUDOX® CL Colloidal Silica can also be used as a high temperature binder. voir moins | Request Sample |

The aqueous colloidal dispersion contains 34% silica and is slightly acidic. LUDOX® TMA Colloidal Silica is used in the preparation of “hybrid” colloidal silica – ethyl silicate binders for precision investment casting. It may also be used in applications in which sodium or alkaline components are undesirable, such as catalysts or in formulations containing polar organic solvents. voir moins | Request Sample |
