US 9,428,651 B2 · Fouling and stiction resistant coating

Abstract

A fouling and stiction-resistant coating suitable for use with marine streamers is made from a silicone undercoat layer and a powdery topcoat layer. The powdery topcoat layer is preferably a non-toxic fluoropolymer which has a low surface energy, a high modulus, and which is not continuous. There may also be a primer layer below the silicone undercoat layer. The powdery topcoat layer is preferably arranged to be penetrable by the feet of barnacles that come into contact with it, with the silicone undercoat layer arranged such that the barnacles' feet that penetrate the powdery topcoat layer bond with the silicone undercoat layer. The powdery topcoat layer is preferably further arranged to peel away from the silicone undercoat layer when force is applied to the barnacles to remove them from the coating.

Dependent claims

A fouling and stiction-resistant coating, comprising:

a silicone undercoat layer;
and
a powdery topcoat layer on said silicone undercoat layer, said coating adapted for application to a surface that is subject to fouling;
said powdery topcoat layer arranged to be penetrable by the feet of barnacles that come into contact with said powdery topcoat layer, and said silicone undercoat layer arranged such that at least some of the barnacles' feet that penetrate said powdery topcoat layer bond with said silicone undercoat layer;
said powdery topcoat layer further arranged to peel away from said silicone undercoat layer when force is applied to barnacles which have penetrated said powdery topcoat layer to remove them from said coating;
such that said coating both resists fouling in the presence of marine life and reduces stiction between surfaces to which said coating has been applied.
