Features & Benefits

Features
  • Silica Powder, processed from selected rocks of very high whiteness & brightness.
  • Material as per buyer’s specification is also available.

Applications & Uses

Typical Applications
  • Silica Extender due to the particle shape, the large particle size and low oil absorption are very helpful in manufacture of wood filler, it is most suitable to fill the pores in open grain woods.
  • Silica extenders are most inert to acids and alkalies, which makes it useful in coatings to give toughness and abrasion resistance.
  • Due to excellent wearing resistance, it is used in Traffic Paint for Making Roadway.
  • It is the basic raw material used in manufacture of glass.
