Non-Toxic, Self-Cleaning Silicone FR Coatings

摘要

The tasks accomplished to date include preparation of 387 panels undergoing preliminary exposure testing at FIT and Miami Marine Research and Testing Station; preparation of 204 downselected panels for exposure at Bridger Scientific, FIT, SUNY Buffalo and the University of Hawaii; preparation and initial evaluation of 17 downselected panels for hydrofoil testing at FIT; deployment of 1 set of bilge keel panels; patch tests on the USS Nevada; and the first of two large scale validations. Statistical analysis shows clear performance differences between downselected coatings. Coatings have been analyzed based on coverage, barnacle, oyster, tubeworm and snail adhesion values, and water jet removal of slimes and hard fouling. Although nearly all coatings have improved performance relative to RTV11, 4 of the downselected coatings show substantially reduced adhesion values. The top performers have been applied to bilge peel panels and test patches. Hydrodynamic drag testing has been performed on several of the downselected coatings.
