Abstract
A water-borne fluoroelastomer coating composition comprising an aqueous dispersion of a fluoroelastomer polymer; from about 0.1 to about 10 parts by weight of an amino/polyamino-siloxane curative per 100 parts by weight of the polymer; and, from 0 to about 40 parts by weight of an additive filler, per 100 parts by weight of the polymer, wherein there is sufficient water to provide a coating composition having a solids content of from about 10 to about 80 percent by weight. A method of coating a substrate with the fluoroelastomer coating composition of the present invention is also provided. Cured fluoroelastomer films, cured with amino/polyamino-siloxane curatives are also provided.
Claims26
A water-borne fluoroelastomer coating composition comprising:
- an aqueous dispersion of a fluoroelastomer polymer;
- from about 0.1 to about 10 parts by weight of a water soluble, stabilized amino/polyamino-siloxane curative per 100 parts by weight of said polymer;
- and,
- from 0 to about 40 parts by weight of an additive filler, per 100 parts by weight of said polymer;
- wherein there is sufficient water to provide a coating composition having a solids content of from about 10 to about 80 percent by weight.
A method of coating a substrate comprising the steps of:
- applying a water-borne fluoroelastomer coating composition to a substrate, wherein the water-borne fluoroelastomer coating composition comprises an aqueous dispersion of a fluoroelastomer polymer;
- from about 0.1 to about 10 parts by weight of a water soluble, stabilized amino/polyamino-siloxane curative per 100 parts by weight of the polymer;
- and,
- from 0 to about 40 parts by weight of an additive filler, per 100 parts by weight of the polymer, and sufficient water to provide a coating having a solids content of from about 10 to about 80 percent by weight.
A cured fluoroelastomer film comprising a layer of fluoroelastomer wherein said fluoroelastomer has been cured with from about 0.1 to about 10 parts by weight of an amino/polyamino-siloxane curative per 100 parts by weight of the fluoroelastomer, wherein the amino siloxane is water soluble.
A cured fluoroelastomer film prepared by:
- applying a water-borne fluoroelastomer coating composition to a substrate, wherein the water-borne fluoroelastomer coating composition comprises an aqueous dispersion of a fluoroelastomer polymer and from about 0.1 to about 10 parts by weight of a water soluble, stabilized amino/polyamino-siloxane curative per 100 parts by weight of the polymer.
