Abstract
A coating composition is disclosed, comprising a binder component having hydroxyl-functional groups; a curing agent having functional groups, wherein the functional groups of the curing agent are reactive with the hydroxyl-functional groups of the binder component; and pulverized rubber, the pulverized rubber having particles with a size suitable for spraying the coating.
Claims31
A coating composition comprising
- (a) a binder component having hydroxyl-functional groups;
- (b) a curing agent having functional groups, wherein the functional groups of the curing agent are reactive with the hydroxyl-functional groups of the binder component;
- and
- (c) pulverized rubber in an amount of about 0.5% or greater by weight of the coating composition, the pulverized rubber having a particle size of about 200 U.S. mesh.
An article comprising a coating, wherein the coating is formed from a composition comprising
- (a) a binder component having hydroxyl-functional groups;
- (b) a curing agent having functional groups, wherein the functional groups of the curing agent are reactive with the hydroxyl-functional groups of the binder component;
- and
- (c) pulverized rubber in an amount ranging from about 0.5% to about 35% by weight of the coating composition, the pulverized rubber having a particle size of 200 U.S. mesh;
- wherein the composition is cured, thereby forming the coating.
The article according to claim 22, wherein the automotive part comprises a mirror housing.
The article according to claim 22, wherein the automotive part comprises a vehicle cladding.
The article according to claim 25, wherein the interior panel is a dashboard.
A process for preparing a coated article comprising
- applying to an article a coating composition comprising
- (a) a binder component having hydroxyl-functional groups;
- (b) a curing agent having functional groups, wherein the functional groups of the curing agent are reactive with the hydroxyl-functional groups of the binder component;
- and
- (c) pulverized rubber in an amount ranging from about 0.5% to about 35% by weight of the coating composition, the pulverized rubber having a particle size of 200 U.S. mesh;
- and
- curing the coating composition;
- wherein the coated article is prepared.
