Abstract
Acid-catalyzed curable coating compositions containing 1,1-di-activated vinyl compounds are described, including multi-layer coatings. Also provided are processes for coating substrates with coating compositions comprising 1,1-di-activated vinyl compounds, Also provided are coated articles comprising coatings formed from coating compositions comprising 1,1-di-activated vinyl compounds.
Claims58
An coating comprising:
- a polymeric resin;
- an acid curing catalyst;
- and
- a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof.
A multi-layer coating comprising:
- a first coating layer applied over at least a portion of a substrate;
- and
- a second coating layer applied over at least a portion of the first coating layer;
- wherein the second coating layer is formed from a coating composition comprising:
- a carbamate-functional resin
- an acid curing catalyst;
- and
- a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof.
A multi-layer coating comprising:
- a first coating layer applied over at least a portion of a substrate;
- a second coating layer applied over at least a portion of the first coating layer, wherein the second coating layer is formed from a coating composition comprising 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof;
- and
- a third coating layer applied over at least a portion of the second coating layer, wherein the third coating layer is formed from a coating composition comprising a carbamate-functional resin and an acid curing catalyst.
Use of a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof to prevent wrinkling in a coating comprising a polymeric resin and an acid curing catalyst, applied over an underlying coating comprising a base.
A process for coating a substrate, comprising:
- applying a coating layer over at least a portion of the substrate, the coating layer comprising:
- a polymeric resin;
- an acid curing catalyst;
- and
- a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof;
- and
- curing the applied coating layer.
A process for coating a substrate, comprising:
- applying a first coating layer over at least a portion of the substrate;
- applying a second coating layer over at least a portion of the first coating layer, the second coating layer comprising:
- a polymeric resin;
- an acid curing catalyst;
- and
- a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof;
- curing the applied first coating layer and the applied second coating layer.
