Abstract

A curable composition is provided, comprising:
(A) a binder composition; and (B) a polysiloxane resin comprising aromatic functional groups and terminal active hydrogen groups. The composition may be used to prepare articles of manufacture and coated articles, such as footwear components. The composition may additionally be used to mitigate dirt build-up on a substrate.

First claim

What is claimed is:

1 . A curable composition comprising:
(A) a binder composition comprising one or more of: (i) a) an isocyanate functional compound and b) an amine functional compound; (ii) a) an acid-functional compound and b) an epoxide functional compound; (iii) a) an ethylenically unsaturated compound and b) an amine functional compound; (iv) a) an isocyanate functional compound and b) a thiol functional compound; (v) a) cyclic carbonate functional compound and b) an amine functional compound; (vi) a) an acetoacetate functional compound and b) an amine functional compound; (vii) a) an epoxide functional compound and b) an amine functional compound; (viii) a) a thiol functional compound and b) an ethylenically unsaturated compound; (ix) a) an ethylenically unsaturated compound and b) a malonate functional compound; (x) a) an epoxide functional compound and b) a thiol functional compound; and (xi) one or more ethylenically unsaturated compounds; and (B) a polysiloxane resin comprising aromatic functional groups and terminal active hydrogen groups.

2 . The curable composition according to claim 1 , wherein the binder composition (A) comprises:
a) an isocyanate-functional prepolymer having a weight average molecular weight of 1300 to 20,000, wherein the isocyanate-functional prepolymer comprises (i) a reaction product of a polyisocyanate and a polyamine having primary and/or secondary amino groups; and/or (ii) a reaction product of a polyisocyanate and a polyol; and b) a mixture of polyamines, wherein at least one polyamine has an amine equivalent weight of 125 to 250.

3 . The curable composition according to claim 2 wherein the polyisocyanate used to prepare the isocyanate-functional prepolymer is aliphatic.

4 . The curable composition according to claim 2 wherein isocyanate-functional prepolymer has an isocyanate equivalent weight greater than 300.

5 . The curable composition according to claim 2 , wherein the isocyanate-functional prepolymer comprises a reaction product of a polyisocyanate and a polyol.

6 . The composition according to claim 2 , wherein the mixture of polyamines comprises 5 to 50 percent by weight of an aliphatic polyamine having an amine equivalent weight of 125 to 250, and 50 to 95 percent by weight of an aliphatic polyamine having an amine equivalent weight of 900 to 2500.

7 . The curable composition according to claim 1 , wherein the terminal active hydrogen groups on the polysiloxane resin (B) comprise hydroxyl and/or carboxylic acid groups.

8 . The curable composition according to claim 1 , wherein the polysiloxane resin (B) comprises urethane linkages.

9 . The curable composition according to claim 1 , wherein the polysiloxane resin (B) is present in the curable composition in an amount of at least 0.5 percent by weight, based on the total weight of resin solids in the curable composition.

10 . A footwear component comprising the curable composition of claim 1 .

11 . The footwear component according to claim 10 , wherein said footwear component comprises an outsole.

12 . A coated article comprising:
A) a substrate having at least one coatable surface, and B) a coating layer formed from a film-forming composition applied to at least one surface of the substrate and cured thereon, wherein the film-forming composition is prepared from the curable composition of claim 1 .

13 . The coated article according to claim 12 , wherein the substrate comprises wood, metal, glass, fabric, leather, a composite, or a polymeric material.

14 . The coated article according to claim 13 , wherein the substrate comprises a plasma-treated surface adjacent to the coating layer formed from the curable composition.

15 . The coated article according to claim 12 , wherein the coated article comprises a footwear component.

16 . The coated article according to claim 15 , wherein said footwear component comprises an outsole.

17 . A method of mitigating dirt build-up on a substrate, comprising:
(1) applying to at least a portion of the substrate the curable composition of claim 1 to form a coated substrate; and (2) at least partially curing the curable composition.

18 . A method of mitigating dirt build-up on a substrate, comprising:
(1) applying to at least a portion of the substrate the curable composition of claim 2 to form a coated substrate; and (2) at least partially curing the curable composition.
