| Popis: | The characteristics and properties of some experimental high-build soluble matrix antifouling paints have been studied. Thixotropic samples were formulated with WW rosin and Grade 10 chlorinated rubber as a binder, using red cuprous oxide as the main toxicant and zinc oxide as the reinforcing toxicant. Non-thixotropic reference samples having the same composition but prepared with Grade 20 chlorinated rubber in the formulation were also used. Rheological additives at 2.0 and 1.0% concentrations were employed for the high-build and conventional formulations, respectively. The paints were tested by means of raft and ship trials to determine their bioactivity. Films of 50–60 and 100–120 μm thickness were evaluated to establish the influence of this variable on the antifouling characteristics of the prepared products. Good antifouling protection extending to 14, 26 and 36 months was obtained with some of the samples tested on raft panels and up to 25 months for the paints applied on the ship hull. |
