              Hydrophilic Fumed Silica for Painting And Coating        

 

 

 

Product Name:         Pyrogenic Silica / White Carbon Black /  Silicon Dioxide

Molecular formula:    SiO2

CAS No.:                      112945-52-5

  

 

 

Product Description:                 

 

 

  

 

 

Nanoscale Fumed SiO2 (CAS number 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles.   

 

 

 

 

Nanoscale Fumed SiO2 can be divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments.

Positive Properties:                                         

 

 

For Hydrophilic Nanoscale Fumed SiO2 

• Optimum adjustment of rheology during processing


• Reinforcement of silicone elastomers


• Thickening of non-polar liquids


• Free-flow of foodstuffs and industrial powders


• High chemical purity


• Excellent insulation properties, even at high temperatures


• Conversion of liquids to powders, e.g. pharmaceuticals, cosmetics


• Gelification of battery acids


• Rheology control of greases and lubricants

 

 For Hydrophobic Nanoscale Fumed SiO2 

• Optimum rheology during processing


• Thickening of polar liquids, e.g. epoxy resins


• Reinforcement of silicone elastomers


• High levels of loading, e.g. molding compounds


• Excellent water-repelling properties, leading to improved corrosion protection


• Improvement of dielectric properties, e.g. in cable compounds


• Free-flow of powders, e.g. in fire extinguishers


• Increased scratch resistance, e.g. in paints and plastics

 

 

 Applicaton:                                                                  

 

 

Nanoscale Fumed SiO2 serves as a universal thickening agent and an anticaking agent (free-flow agent) in powders. Like silica gel, it serves as a desiccant. It is used incosmetics for its light-diffusing properties. It is used as a light abrasive, in products like toothpaste. Other uses include filler in silicone elastomer and viscosity adjustment in paints, coatings, printing inks, adhesives and unsaturated polyester resins. It is also used in the production of cat litter box filler.
