Non-toxic Novel Silicone Foul-release Marine Coatings

This study evaluates modified silicone elastomers as foul-release coatings. The coatings are easy to apply, cure rapidly and relatively tough materials. They are non-toxic and biologically inert but still prevent the adhesion of marine life. The coatings were tested by a novel barnacle adhesion test with adhesion results in two weeks. The test consisted of coated glass slides upon which a barnacle was transferred from one substrate and re-attached to the test slide. After the barnacle re-attached, the adhesion was directly measured by a force displacement tester. Results are measured in psi.
