Abstract:
1. A method for applying a thermoplastic anti-fouling coating onto a marine surface, the method comprising: (a) depositing a tie coat comprising both a polyamine curing agent and a resin onto the marine surface under ambient conditions, wherein the tie coat has a time for complete curing, and is fluid at ambient temperature; (b) heating a thermoplastic, anti-fouling material that is solid at ambient temperature to a temperature greater than 250° F., at which the material has the viscosity of a finishing material, wherein the thermoplastic, anti-fouling material comprises rosin as a binding ingredient and at least one toxic agent; (c) spraying the heated thermoplastic material from (b) at a spraying-temperature in the range of from 250° F. to 450° F. onto said tie coat within said time for complete curing; and (d) allowing the tie coat to cure completely and allowing the sprayed material from (c) to cool and harden, thereby forming a top coat having a thickness greater than the thickness of the tie coat.
