Abstract

Provided is a polymer coating composition for a surface layer, comprising a product of a grafting reaction between a fluoroelastomer and at least one of an aminosilane component and an aminofunctionalized fluorosilicone component.

First claim

What is claimed is:

1. A method for forming a coating, comprising:
forming a graft polymer composition by grafting at least one of an aminosilane component and an aminofunctionalized fluorosilicone component with a fluoroelastomer;
crosslinking the at least one of an aminosilane component and an aminofunctionalized fluorosilicone component;
depositing a layer of the graft polymer composition on a substrate; and
curing the layer to form a grafted polymer coating,
wherein the aminosilane component is present in an amount relative to an amount of the fluoroelastomer of about 2 pph to about 10 pph, and wherein the aminofunctionalized fluorosilicone component is present in an amount relative to an amount of the fluoroelastomer of about 2 pph to about 10 pph.

2. The method of claim 1 , wherein the curing is performed at a temperature of lower than about 218° C.

3. The method of claim 2 , wherein the curing is performed at a temperature of about 140° C.

4. The method of claim 1 , wherein the aminosilane component comprises an oxyaminosilane.

5. The method of claim 4 , wherein the oxyaminosilane is represented by Formula (1):
Si(OR) p R′ q (-L-NH 2 ) 4-p-q   (1),

where R is hydrogen or alkyl, p is an integer from 1 to 3, R′ is an alkyl, q is an integer from 0 to 2, L is a linking group, and 4-p-q is at least 1.

6. The method of claim 1 , wherein the aminofunctionalized fluorosilicone component comprises an aminofunctionalized alkoxy-terminated fluorosilicone.

7. A method for forming a coating, comprising:
forming a graft polymer composition by grafting at least one of an aminosilane component and an aminofunctionalized fluorosilicone component with a fluoroelastomer;
crosslinking the at least one of an aminosilane component and an aminofunctionalized fluorosilicone component;
depositing a layer of the graft polymer composition on a substrate; and
curing the layer to form a grafted polymer coating,
wherein the aminofunctionalized fluorosilicone component is present in an amount relative to an amount of the fluoroelastomer of about 2 pph to about 10 pph.

8. The method of claim 7 , wherein the curing is performed at a temperature of lower than about 218° C.

9. The method of claim 8 , wherein the curing is performed at a temperature of about 140° C.

10. The method of claim 7 , wherein the aminosilane component comprises an oxyaminosilane.

11. The method of claim 10 , wherein the oxyaminosilane is represented by Formula (1):
Si(OR) p R′ q (-L-NH 2 ) 4-p-q   (1),

where R is hydrogen or alkyl, p is an integer from 1 to 3, R′ is an alkyl, q is an integer from 0 to 2, L is a linking group, and 4-p-q is at least 1.

12. The method of claim 7 , wherein the aminofunctionalized fluorosilicone component comprises an aminofunctionalized alkoxy-terminated fluorosilicone.
