Abstract: Aqueous sealant compositions wherein the thickening agent is a polymer containing repeating units derived from the ammonium salt of acrylic or methacrylic acid adhere well to coated metal substrates. Following evaporation of the aqueous phase the sealant exhibits a unique ability to swell when in contact with the liquid contents of a closed container, thereby ensuring that an impervious seal will be maintained at the seams of the container.
