All cast iron, steel & malleable iron foundries are almost using Bentonite with cost efficient results, kutch region is famous for a very good sodium Bentonite for casting industries. For continuous mould making also kutch Bentonite is used successfully. Our foundry grade Bentonite powder gives good flow ability. Compact ability and thermal stability for the production of high quality castings
Following parameters help to make high quality castings
- High gelling time which gives high strength in less mulling time
- pH Maintaining
- Active clay maintaining
- High strength on good compatibility
