  • Aqueous sealant from alkali silicate, liquid polysulfide polymer and coal tar
    Patent number: 3986996
    Abstract: Curable liquid polymers selected from mercaptan-terminated polysulfide polymers, polyepoxides and oganosilicon polymers are extended by mixing therewith, prior to curing 10% to 200% by weight, based on the weight of liquid polymer, of an aqueous colloidal dispersion selected from aqueous alkali metal silicates having an M.sub.2 O:SiO.sub.2 ratio of 0:1 to 1:1 and aqueous magnesium oxide. Upon curing of the mixture to solid form, nearly all of the water of the aqueous dispersion remains bound in the solid cured material and little, if any, shrinkage occurs.
