  • Mine stopping caulk
    Patent number: 4687790
    Abstract: A process for sealing geological formations and mine stoppings by applying to these substrates an aqueous, non-cementitious caulk composition comprising an alkali metal silicate; filler material including at least one silica product or silicate other than an alkali metal silicate; a water-soluble or water-dispersible polymer modifier; and water, and allowing the caulk composition to dry to form an air flow resistant seal on the substrates. A highly satisfactory polymeric modifier is used in the form of a polymer emulsion, such as an emulsion of a self-plasticizing acrylic polymer having a low Tg.
    Type: Grant
    Filed: June 4, 1986
    Date of Patent: August 18, 1987
