Non activated
Are produced of selectively exploited raw materials, homogenised, carefully dried and ground. BENTONIT 70 is especially suitable for activating of filling moulding mixtures. BENTONIT 75 is a quality bentonite suitable for preparation of moulding mixtures for castings with short casting time of max. 15 sec.
It can be further used as a flocculation heavy medium by waste water purifying, buffer for improving soil imperviousness, retaining of moister and nutrients in soil, powder extinguishers, thickening agents for farm waste and dung, plastification additive in mortars, facades and ceramic masses, additive to granulated fodder.
