The ultra long life foul release. Copper plate your boat.
SPRAY INSTRUCTIONS FOR USE.
DIRECTIONS FOR USE
We recommend that Cop-R-Bote should be spray applied in preference to roller or brush application. The reason for this is that, after the coating has cured, it must be sanded to expose the copper metal to obtain optimum foul release effect. A very smooth coating will require less sanding to achieve this, and the smoothest coating will be obtained by spray application. There is, however, nothing wrong with roller or brush application, they will simply require more sanding to obtain the desired finish.
When spraying it is important to take full precautions to avoid
breathing the vapour or having it get onto unprotected skin.
EQUIPMENT
Cop-R-Bote cannot be sprayed through a
conventional (suction) gun.
It is best sprayed through a
gravity feed unit, or similar, where the paint is fed by gravity
into the gun from a pot fitted above the gun. This will require
frequent refilling as only small volumes can be handled at a
time. The benefit of such a gun is that no copper can settle out
and be lost. A tip size of 2.0 mm is satisfactory, at a pressure
around 400 kPa (50 psi).
Alternatively, a stirred pressure
pot may be used, together with a gun suitable for application of
high build primers. The preferred tip size is 0.50 to 0.65 mm
(0.020” to 0.025”). The pressure pot must be stirred or agitated
frequently to prevent settling of the copper.
APPLICATION
Do not thin Cop-R-Bote for sprayiing.
Addition of thinners will cause the copper particles to settle
out of suspension quickly.
Always stir or agitate the mixed
Cop-R-Bote frequently during application, to ensure that the
copper remains uniformly dispersed in the liquid.
Adjust the
fluid and air needles to ensure that sufficient fluid is being
applied to the surface without causing runs, that there is
sufficient air pressure to atomise well, but not so much air as
to dry the f luid excessively and cause ‘orange peel’ or
un-coalesced coating film. A smooth glossy film should be
obtained readily.
Apply two coats of Cop-R-Bote, preferably
apply the second while the first is still tacky, usually within
an hour or two of the first coat unless drying is retarded in
cold weather. If the first coat is left to cure hard, it should
be abraded lightly to provide a key for the second coat.
FINISHING
Abrade the final Cop-R-Bote surface with 180
grit abrasive paper, and finish with 240 grit if an especially
smooth finish is preferred. Abrading it will remove the epoxy
paint film from the surface of the copper particles, and the
surface will assume a bright metallic copper appearance. At
least 75% of the surface should appear as bright metal, the
balance may be in the bottom of small streaks or dimples which
would require too much sanding to expose copper at the bottom.
SAFETY
Refer to the product SDS. This is an epoxy. Eye
protection must be used. Breathing and skin protection must be
used whilst spraying. Dust protection for eyes and lungs is
recommended whilst sanding the product.
A clean air supply
for the operator is recommended. Refer to the
safety page.
