Abstract: A process for forming a cured fluoroelastomer film comprising the steps of providing a fluoroelastomer latex, adding an organic peroxide curing agent and coagent to the latex to form a curable coating composition, forming a film with the curable coating composition, and curing the film at elevated temperature.
Abstract: A water-borne fluoroelastomer composition comprising an aqueous dispersion of a fluoroelastomer polymer, from about 2 to about 30 parts by weight per one hundred parts by weight of polymer of a curative system, said curative system having been formed by blending from about 6 to about 94 parts by weight of a stabilized siloxane and from about 94 to about 6 parts by weight of a non-stabilized silane, where said stabilized siloxane and said non-stabilized silane total about one hundred parts by weight of the curative system, from 0 to about 40 parts by weight of an additive filler per one hundred parts by weight of polymer, and sufficient water to provide a composition having a solids content of from about 10 to about 80 percent by weight of the total composition.

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.
