A method, and an article made therefrom, of: contacting a substrate with a first solution of first polyelectrolyte chains to form a layer of the first polyelectrolyte on the substrate; and contacting the layer of the first polyelectrolyte with a second solution of second polyelectrolyte chains to form a layer of the second polyelectrolyte. The first polyelectrolyte has a polyanion or polycation chain. The second polyelectrolyte has a polyanion or polycation chain of a charge opposite to that of the first polyelectrolyte. The first solution or the second solution is an aggregate-forming solution comprising an ionic species having at least two discrete sites of a charge opposite to that of the polyelectrolyte chains in the aggregate-forming solution. The ionic species forms, via bridging interactions, aggregates of the polyelectrolyte chains that remain intact in the aggregate-forming solution during the contact.

A method, and an article made therefrom, of: contacting a substrate with a first solution of a first polyelectrolyte polymer to form a layer of the first polyelectrolyte polymer on the substrate; and contacting the layer of the first polyelectrolyte polymer with a second solution of a second polyelectrolyte polymer to form a layer of the second polyelectrolyte polymer on the layer of the first polyelectrolyte polymer.

At least one of the first solution or the second solution is an aggregate-forming solution comprising an ionic species having at least two discrete sites of a charge opposite to that of the polyelectrolyte polymer in the aggregate-forming solution. The ionic species forms, via bridging interactions, aggregates of the polyelectrolyte polymer that remain intact in the aggregate-forming solution during the contact and layer formation.

A two-part sealant composition, wherein this composition comprises a first part and a second part. The first part comprises a polymer selected from a silane-terminated polyurethane or a silane-terminated polyether, wherein this polymer is present in an amount of up to 100% by weight of the first part of the sealant composition. The second part comprises a plasticizer that it is compatible with the polymer and a filler comprising at least 0.5% by weight of residual water, wherein the filler comprises at least one rheological filler, and wherein the filler is present in an amount of 80-20% by weight of the second part of the sealant composition. The first and second parts are separated from one another, and the amount of polymer present in the first part makes up 4-50% by weight of the first and second parts taken together. In use, the first and second pans are mixed to achieve a cured substance having a 48 hour Shore A hardness in the range of 25-70.
