Abstract
Fluoroelastomer surfaces and a method for providing a fluoroelastomer surface on a supporting substrate which includes dissolving a fluoroelastomer; adding a dehydrofluorinating agent; adding an amino silane to form a resulting homogeneous fluoroelastomer solution; and subsequently providing at least one layer of the homogeneous fluoroelastomer solution to the supporting substrate.
Claims20
A method for providing a fluoroelastomer surface on a supporting substrate comprising in sequential order:
- a) dissolving a fluoroelastomer;
- b) adding a dehydrofluorinating agent to said dissolved fluoroelastomer;
- c) adding and reacting an amino silane in an amount of from about 0.5 to about 10 percent based on the weight of said fluoroelastomer to the product of (b) to form a homogeneous fluoroelastomer solution;
- and
- d) subsequently providing at least one layer of said homogeneous fluoroelastomer solution to said supporting substrate.
A method for providing a fluoroelastomer surface on a supporting substrate comprising in sequential order:
- a) dissolving a fluoroelastomer;
- b) adding a dehydrofluorinating agent to said dissolved fluoroelastomer;
- c) adding and reacting an amino silane having the formula NH.sub.2 (CH.sub.2).sub.n NH(CH.sub.2).sub.m Si(OR).sub.t (R').sub.w !, wherein n and m are from about 1 to about 20, t+w=3;
- and R and R' are an aliphatic hydrocarbon chain with from about 1 to about 20 carbon atoms or an aromatic group with from about 6 to about 24 carbons, in an amount of from about 0.5 to about 10 percent based on the weight of said fluoroelastomer to the product of (b) to form a homogeneous fluoroelastomer solution;
- and
- d) subsequently providing at least one layer of said homogeneous fluoroelastomer solution to said supporting substrate.
