advisable to apply it too early; in summer, application within two days before the antifouling paint; in winter, within seven days.
the quantity used shall not be omitted or reduced at will. As film thickness increases, anticorrosive and antifouling performance increases
accordingly and the docking interval can be extended. This is economically viable. Antifouling paint relies on the
toxic agents in the film leaching gradually into seawater to prevent marine organism attachment. Ensuring the antifouling
paint reaches a certain thickness (i.e. number of coats or quantity applied) is required for effectiveness within a given period.
If the antifouling paint is applied too thin, the amount of toxic agents in the film decreases accordingly and lasting antifouling
performance cannot be achieved.
iron anticorrosive paint, zinc yellow anticorrosive paint, red lead anticorrosive paint and similar primers shall not be used.
viscosity is too high for brushing or spraying, a small amount of thinner may be added. Turpentine shall not be used,
otherwise the paint will coagulate and become unusable.
soft and the potential resistance is poor; the potential shall not exceed -0.8 V. Exceeding this potential will cause film
blistering and detachment, marine organism attachment and other adverse effects.
