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.

Abstract: The cure or vulcanization rate of a rubber compound can be increased without adverse effects on the properties of the resulting cured rubber or rubber vulcanizate by replacing stearic acid or other acid in the rubber activator system with an amide like stearamide for activation of the sulfenamide acceleration of the vulcanization of rubber.
