Product Description
Shanti Chemical Works manufactures Precipitated Silica is valued globally for its properties index. This agent is used for thickening the end products along with anti corrosion pigments in order to enhance the durability and sustainability of coatings, paints, inks, sealants, etc. The compound majorly has silicon dioxide (SiO2) in its composition. Holding a great industrial significance, Precipitated Silica is a dry powder with least amount of moisture in it. The purity level is more than 98 % and is free from any harmful contaminants (unless directly consumed). It has a very high ignition point which makes the end products in which it is used quiet endurable and resistant towards the external conditions.
