Abstract
Marine anti-fouling compositions contain, in addition to the conventional resin, toxin, solvent, pigment and other additives, hollow particles, of size from 1 to 800 microns, in an amount to give a particle concentration in a dry paint film of 10 to 80% by volume. The hollow particles are preferably hollow microspheres or microballoons of glass or plastics material having an apparent bulk density of from 0.03 to 0.5 g/cc. The compositions can be applied at high film thicknesses in a single coat without crack-formation. The particles assist in maintaining a controlled slow release of toxin from the paint film, and can enhance the useful protective life thereof.
