Applications         
Because of its special pore structure SG-3 white,wide porousis applied for many technical processes. It is mainly used as catalyst and carrier of catalyst in varied chemical and petro-chemical processes as well as petrol refining, for dehydration and purification of liquids, as moisture proof protection layer in drying apparatus.

Packing             
Airtight in 20 kg cartons with PE-Inliner,Airtight in 500 kg bulk bags with PE-Inliner.

Handling           
SG-3must always be kept in airtight containers to avoid pre-adsorption with water vapour. Face masks should be used at continual exposure to extensive dusting.
