Novel Coating Formulations Exhibiting Anti-Fouling Properties for Marine Vessels
Coatings utilizing these compounds significantly reduce the amount of fouling on the exterior of these ships which, in turn, convey certain advantages such as reduced drag in water with concomitant improvements in performance, such as decreased fuel consumption and reduced fleet costs.
This invention involves novel polysiloxane-polycaprolactone block copolymers where the linking group between the blocks is a carbamate group. This linking group provides better compatibility of the block copolymer with polyurethane coating compositions. Also included are star branched block copolymers where the linear polysiloxane polymer forms the central segment and multiple caprolactone polymers radiate from the two end groups, and crosslinked polyurethane coatings prepared from these block copolymers.
