• Wet film gauge
• Airless spray
Because some paint types may be aggressive to the polyurethane in the transducer,
consult our list of approved paints.
Context
The transducer has not been designed with any protection against biological fouling.
Anti-fouling paint may therefore be applied to the transducer face. To minimize the
negative acoustical effects the layer of anti-fouling paint must be as thin as possible.
Note
The anti-fouling paint will reduce the acoustical performance of the transducer. The
surface roughness of the transducer substrate and the thickness of the paint may also
influence the performance. Kongsberg Maritime cannot be held responsible for any
negative consequences of the anti-fouling paint.
Observe the relevant instructions and safety information provided by the paint
manufacturer.
Procedure
1
Clean the transducer thoroughly.
Make sure that you remove all oil grease residues, as well as salt and other
contamination.
2
Allow the transducer surface to dry.
3
Abrade the transducer surface using a sanding paper with 240 inch grit size.
Do not exceed a surface roughness (R
ES38DD performance.
4
Remove all dust.
5
Apply the primer, and let it dry.
6
Apply the paint.
Observe the instructions provided by the paint manufacturer. Use airless spray.
Apply the minimum specified film thickness per coat and for the complete layer.
It is not possible to measure dry film thickness on transducer surface. You must
therefore use a wet film gauge to frequently measure the paint thickness.
Note
We strongly recommend that you do not use a paintbrush and/or a roller.
