Colloidal Silica - A Versatile Problem Solver, Product Article

Binder Applications

LUDOX® colloidal silica forms strong ionic and hydrogen bonds with granular and fibrous material.  These bonds are thermally stable and chemically inert making them especially useful for:

• Investment Casting Slurries
• Vacuum Formed Refractories
• Specialty Coatings
• Catalysts
• Insulation Board

Surface Modification Application

The silica particles in LUDOX® adhere well to many surfaces via ionic and hydrogen bonding.  Once applied to a surface the silica particles provide an increased coefficient of friction that is useful for:

• Paper & cardboard
• Flooring
• Polishing Slurries
• Industrial and architectural coatings

Flocculant Applications

LUDOX® colloidal silica is available in grades with anionic sol charge as well as cationic sol charge.  When added to solutions  LUDOX® particles bond ionically with particles of the opposite charge and fall out of suspension.  This makes LUDOX® an excellent flocculant for:

• Paper retention and drainage
• Beverage fining (beer and wine)
• Insulation board

The characteristics of LUDOX® Colloidal Silica and it's usefulness as a binder and surface modifier are further highlighted in the short video below.
 

Today, LUDOX® colloidal silica is used in applications ranging from a high temperature binder for the production of aerospace parts to a fining agent used to produce beer and wine. LUDOX® functions in commercial applications in three major ways; as a binder, surface modifier, and flocculant.LUDOX® colloidal silica forms strong ionic and hydrogen bonds with granular and fibrous material.

Dirt is attracted to surfaces that are hydrophobic, in other words, afraid of water. When surfaces are more hydrophilic, or water loving, dirt is repelled. This is called anti-soiling.

Silica particles in colloidal silica dispersions have many surface hydroxyl-silanol groups, which are very hydrophilic. Thanks to the enrichment of colloidal silica particles in the coating surface you get a less tacky and more hydrophilic surface. This means that water forms a film on the surface, allowing dirt to run off with the water.
