Key properties

• Merchant ship antifouling with high cost-effectiveness.
• Selected broad-spectrum antifouling biocides to suit multiple routes.
• Mature technology with stable performance proven by long-term service records is retained.
• Broad compatibility with anticorrosive coating systems for the underwater area of vessel hulls.
• Suitable for the outer hull plating of seagoing vessels, workboats and barges.

Colour and gloss

• Red-brown and brown.
• Flat.

Basic data at 20 °C (68 °F)

Parameters after mixing

390.0 g/L (3.3 lb/gal) (US EPA Method 24).

Notes

• See the supplementary data sheet — theoretical spreading rate versus dry film thickness table.
• See supplementary parameters — recoat interval table.

Recommended substrate condition and temperature

Substrate condition

• Surface cleaning by high-pressure fresh water washing and/or abrasive blasting is selected according to the overall condition of the hull outer-plate coating system and the polishing state of the existing antifouling coating.
• Spot repair or overall coating of a build-up nature: dust, contaminants and loose antifouling or other coatings shall be removed from the surface first.

Areas of the existing coating with fouling

• Where heavy marine growth and fouling are present, removal shall first be carried out with scrapers and/or sweep blasting.
• High-pressure water washing removes loose, poorly adhered existing coating and residual marine growth while cleaning the surface.
• Intact, firmly adhered anticorrosive and antifouling coatings may be retained.

Substrate temperature and application conditions

• During application, the substrate surface temperature must be maintained at least 3 °C (5 °F) above the dew point.

Instructions for use

• Stir thoroughly before application.
• Before application, raise the temperature of the components or the mixed paint to above 15 °C (59 °F); otherwise, thinner may need to be added to bring the paint viscosity

adjust to a state suitable for application.

• Excessive thinning generally reduces the sag resistance of the wet film.

Notes

• The above data are reasonable indicators for common application conditions.
• With excessive film thickness or adverse climatic conditions, longer drying times may be required.

Safety Precautions

• For the coating and its recommended thinners, see Safety Sheets 1430 and 1431 and the relevant Material Safety Data Sheet.
• This is a solvent-borne coating. Avoid inhaling spray mist and solvent vapours, and avoid contact of uncured paint with skin and eyes.
