Abstract
A composition for use in the manufacture of a fouling release coating, e.g. at least one layer of a fouling release coating, comprising at least one curable or crosslinkable polysiloxane and at least one silane terminated polyurethane.
Claims8
A multilayer fouling release coating comprising:
- (I) an epoxy primer layer on a substrate;
- (II) a layer comprising at least one polysiloxane and at least one silane terminated polyurethane directly over the layer (I), wherein said at least one polysiloxane is a silanol terminated polysiloxane;
- and
- (III) a polysiloxane layer top layer directly over the layer (II), wherein said polysiloxane top layer is free of silane terminated polyurethane,
- wherein said multilayer fouling release coating is free of any marine biocide, and
- wherein the polysiloxane and polyurethane of layer (II) are present in a weight ratio from 10:1 to 2:1.

A multilayer fouling release coating comprising:
- (I) an epoxy primer layer on a substrate;
- and
- (II) a layer comprising polysiloxane and at least one silane terminated polyurethane directly over the layer (I) which have been cured, wherein said polysiloxane is a silanol terminated polysiloxane;
- and
- (III) a polysiloxane layer top layer directly over the layer (II), wherein said polysiloxane top layer is free of silane terminated polyurethane,
- wherein said multilayer fouling release coating is free of any marine biocide, and
- wherein, prior to curing, the polysiloxane and polyurethane of layer (II) are present in a weight ratio from 10:1 to 2:1.
4 more elements
A multilayer fouling release coating comprising:
- (I) an antifouling coating or fouling release layer on a substrate;
- (II) a layer comprising at least one polysiloxane and at least one silane terminated polyurethane directly over the layer (I), wherein the layers (I) and (II) are different;
- and
- (III) a polysiloxane top layer directly over the layer (II), wherein said polysiloxane top layer is free of silane terminated polyurethane,
- wherein said multilayer fouling release coating is free of any marine biocide, and
- wherein the polysiloxane and polyurethane of layer (II) are present in a weight ratio from 10:1 to 2:1.

- and
- (III) a polysiloxane top layer directly over the layer (II), wherein said polysiloxane top layer is free of silane terminated polyurethane,
- wherein said multilayer fouling release coating is free of any marine biocide, and
- wherein, prior to curing, the polysiloxane and polyurethane of layer (II) are present in a weight ratio from 10:1 to 2:1.
