Abstract
Fluoroelastomer surfaces and a method for providing a fluoroelastomer surface on a supporting substrate which includes dissolving a solid fluoroelastomer in a solvent, adding an amino silane in order to effect coupling and crosslinking and to form a resulting homogeneous fluoroelastomer solution, and subsequently providing a layer of the homogeneous fluoroelastomer solution to the supporting substrate is provided herein.
Claims19
A ball milling-free and roll milling-free method for providing a fluoroelastomer on a supporting substrate comprising:
- a) dissolving a fluoroelastomer;
- b) adding and reacting an amino silane in an amount of from about 0.5 to about 10 weight percent based on the weight of said fluoroelastomer to said dissolved fluoroelastomer to form a resulting homogeneous fluoroelastomer solution;
- and
- c) subsequently providing at least one layer of the homogeneous fluoroelastomer solution to said supporting substrate.
A method for providing a fluoroelastomer surface on a supporting substrate comprising:
- a) dissolving a fluoroelastomer;
- b) adding and reacting N-(2-aminoethyl-3aminopropyl)-trimethoxy silane to said dissolved fluoroelastomer to form a resulting homogeneous fluoroelastomer solution;
- c) subsequently providing at least one layer of the homogeneous fluoroelastomer solution to said supporting substrate.
A ball milling-free and roll milling-free method for providing a fluoroelastomer surface on a supporting substrate comprising:
- a) dissolving a fluoroelastomer;
- b) 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 a number of from about 1 to about 20;
- t+w=3;
- and R and R' are an aliphatic hydrocarbon chain having from about 1 to about 20 carbon atoms or an aromatic group having from about 4 to about 18 carbons in an amount of from about 0.5 to about 10 weight percent based on the weight of said fluoroelastomer, to said dissolved fluoroelastomer to form a resulting homogeneous fluoroelastomer solution;
- c) subsequently providing at least one layer of the homogeneous fluoroelastomer solution to said supporting substrate.
