International Interthane 990E

International Interthane 990E is a two component solvent borne, high solids aliphatic acrylic polyurethane topcoat with optimised application properties and superior aesthetics. Formulated as a cosmetic finish above water in marine environments.

Best Uses

International Interthane 990E is ideal as a cosmetic finish on above water areas. Suitable for use on topsides, external superstructure, external decks and boottops. For use at Newbuilding, Maintenance & Repair or On Board Maintenance. Can be applied down to -5 degrees Celsius.

Interthane 990E must be applied over a recommended primer system, which will vary depending upon the vessel area. Direct application is acceptable over the following marine anti-corrosives:

• Intergard 264 (USA)
• Intergard 5600
• Intergard 7500
• Intergard 7600
• Intershield 300
• Intershield 300HS
• Intershield 803
• Intershield One-2-One
• Interstores Alkyd Primer

A tiecoat of Intergard 263, Intergard 267 or Intergard 269 may be required if Interthane 990E is to be applied over other epoxy primers and may also be used to extend the maximum overcoating interval when Interthane 990E is to be applied over those primers listed above.

Interprime 198 may also be used as a primer for Interthane 990E.

Application

Use in accordance with standard Worldwide Marine Specifications. All surfaces to be coated should be clean, dry and free from contamination. High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.

NEWBUILDING/MAJOR REFURBISHMENT
Interthane 990E should always be applied over a recommended primer coating scheme. The primer surface should be dry and free from all contamination, and Interthane 990E must be applied within the overcoating intervals specified (consult the relevant product data sheet). For boottop areas the overcoating intervals for primers are reduced. Areas of breakdown, damage etc. should be prepared to the specified standard (eg. Sa2½ (ISO 8501-1:2007)) and primed prior to the application of Interthane 990E.

REPAIR/OBM
Interthane 990E should always be applied over a recommended primer coating scheme. The primer surface should be dry and free from all contamination, and Interthane 990E must be applied within the overcoating intervals specified (consult the relevant product data sheet). For boottop areas the overcoating intervals for primers are reduced. Areas of breakdown, damage etc. should be prepared to the specified standard (eg. Sa2½ (ISO 8501-1:2007)) and primed prior to the application of Interthane 990E. Interthane 990E may be applied directly over aged Interthane 990E following thorough fresh water washing and degreasing, provided the coating to be overcoated is in an intact and tightly adherent condition. Loose or flaking coatings should be removed back to a firm edge and Interthane 990E or an appropriate primer should be used to repair the area before application of the full coat.

This product may be applied directly over most generic types of paint that have been aged for at least 3 months. It is advisable that a small trial be carried out before applying a full coat.

Apply in accordance to datasheet recommendations.
