Clear, transparent acrylic plastics were treated with bistri-n-butyltin oxide TBTO under hydrostatic pressure of 3000 psi and 10,000 psi. In addition, some panels were simply dipped in TBTO. These were tested and evaluated in biologically active water to determine the effectiveness of the treatment against fouling attachment. For comparison purposes, non-treated control panels were also submerged in the sea. The acrylic panels pressure treated with TBTO under 3000 psi were relatively free of fouling attachment after nine days exposure. The 10,000 psi pressure-treated panels, dip-treated panels, and control panels, were relatively free of marine growth after 18 days exposure. The visibility through the test panels was very good. However, after 30 days submergence, the various pressure-treated, dip-treated and control panels became covered with marine growth. Author
