The object of this paper is to establish the behaviour of high-build antifouling paints. The influence in the bioactivity of the WW rosin/chlorinated rubber ratio, binder percentage, cuprous oxide content, castor oil amount incorporated as gel, dispersion time of the toxicant and also dry film thickness were the variables studied.

Samples preparation was achieved on a laboratory scale using a highspeed disperser and a ball mill with a 3.3-liters,jars. The bioactivity was performed by means of trials in a marine zone with aggressive fouling. Fouling attachment on the panels was determined after 25-month immersion.

The values of antifouling efficiency were statistically treated according to the factorial design 3 x 2 x 2 x 2 x 2 x 2. The variance of the mentioned effects and of the experimental error (residual variance) permitted the calculation of F values. Then the antifouling coat with best performance was selected.
