organotin for example, tributyltin oxide (TBTO) to rosin-based paints. This efficiency
was further enhanced when the organotin release rate was lastly regulated by the
tributyltin self-polishing co-polymer paints.
20.3 Methodology
This section describes and proceeds in determining the corresponding properties,
field testing, and analysis in the process of conducting experiment. It also describes
the sequence flow of the project and proposed planning in order to achieve expected
outcome.
In general, it required to construct a field testing site to collect data and analyse
it. The methodology of field testing was applied which involved data collection and
analysis from the field are testing. Subsequently, methods used for the field testing
were lined up to provide the results within the project.
20.3.1 Binders
The type of anti-fouling paint that is used is a Self-polishing co-polymer. However,
there are three different binders considered: Copper-acralyte, Zinc-acralyte, and
Silyl-acralyte. Each paint will be painted on specimens with three different thicknesses by strictly following the paint TDS guidelines. This means in regards to its
primer, thinner, surface preparations, and dryness time. All three binders are associated with the following paints brand: (1) Copper-acralyte will be Jotun Seaforce 90
and Chugoku Sea Grandprix 220 HS, (2) Zinc-acrylate will be Chugoku Seaflo Neo
CF Z, and (3) Silyl-acralyte will be Intersmooth 7465si and Jotun Seamate M.
20.3.2 Thickness of Paint
Different thicknesses of anti-fouling paint are used in order to determine the efficiency
of the anti-fouling paint for a given thickness. Thickness of anti-fouling will be based
on ASTM D3623-78a and paint manufacturer guidelines.
20.3.3 Underwater Depth
Different depths are used to immerse the test specimens. The reason is to correlate the
efficiency of anti-fouling paint under different depths of water. The depth that is used
is ranging from minimum of 0.3 m to maximum 3 m based on ASTM D3623-78a.
