Abstract
A sealing compound for pipe joints which has a pastelike consistency and is formulated from inert filler particles, an aqueous dispersion of fluorocarbon particles, an acidic gelling agent and an alkali activator for the gelling agent in a relative quantity producing a neutral pH, the activator including an ingredient which imparts freeze-thaw stability to the compound.
Claims8
A sealing composition comprising an inert filler, an aqueous dispersion of polymers of tetrafluoroethylene lubricating particles in which particles of colloidal size are intermingled with particles of microscopic size, an acidic gelling agent, and an alkali activator for the gelling agent, said activator including an ingredient which renders the compound freeze-thaw stable.
