Abstract
A crosslinkable acrylic copolymer sealant composition has a stabilized viscosity in that the viscosity does not unduly increase nor does the material gel on storage for periods of time up to and including one year. The stabilized viscosity is unexpectedly achieved by adding moisture scavengers either before and/or during the polymerization of the various monomers. The sealant composition is suitable for use in high movement applications as well as to metal and glass substrates.
