Abstract
Suspension, having a high storage stability, comprising an aqueous silicate solution and a filler material, wherein the silicate solution has a silicate content of at least 20% by weight, the filler material has an average particle size of 0.8 to 15 μm and a specific weight of below 2.75 Kg/l.
Claims28
A suspension having a high storage stability comprising an aqueous silicate solution and a filler material, wherein the suspension has a silicate content of at least 20% by weight, the filler material has an average particle size of 0.8-15 μm and a specific weight of below 2.75 kg/l, the filler being selected from the group consisting of:
- a) zeolites,
- b) fine particulate or fibrous amorphous inorganic material being relatively inert in an alkaline aqueous solution, comprising amorphous alkali metal alumino silicate, and
- c) mixtures thereof, and
- wherein said suspension has a high storage stability in the absence of a stabilizer.
