Interlac 665 Alkyd Topcoat is an alkyd paint, used as a topcoat. Can be used for maintenance in various industrial environments, including offshore installations, petrochemical plants and chemical plants. A single-component alkyd resin high-gloss enamel. Interlac 665 is not suitable for recoating over epoxy or polyurethane coatings, and must not be recoated over zinc-containing primers, because this may cause saponification of the alkyd resin and loss of adhesion. Parameters on this page: volume solids 48% ± 3% (depending on colour), theoretical spreading rate 12 m²/L, components single-component.

All surfaces to be coated must be clean, dry and free of contaminants. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
Pre-primed surfaces: Interlac 665 should always be applied over the recommended anti-rust primer. The primer surface should be dry and free of any contaminants, and Interlac 665 must be applied within the specified overcoating interval (see the relevant product data sheet).
Cracked, damaged areas etc. shall be treated to the specified standard (e.g. Sa 2½ (ISO 8501-1:2007), SSPC SP6, or SSPC SP11) and the primer repaired before applying Interlac 665.

| Thinner | International GTA004 | Do not exceed the thinning limits of local environmental regulations |
| Cleaner | Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations. |
|---|---|
| Interruption of work | Flush all equipment thoroughly with International thinner. All unused paint shall be stored in closed containers. After a period of storage, skinning may occur in partly filled containers and the viscosity may increase. Strain the paint before use. |
| Cleaning | All equipment shall be cleaned with International thinner immediately after use. Periodic flushing of spray equipment during application is also recommended. The frequency of cleaning depends on the quantity sprayed, temperature and time, including all interruptions. |
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
Interlac 665 is designed primarily for on-site application. Airless spray application in the workshop easily causes over-application, slowing drying and causing handling difficulties. Over-application also causes wrinkling when recoating after aging. Other alkyd resin coatings are more suitable for workshop use. Consult International Protective Coatings for corresponding information.
Gloss and surface evenness depend on the application method. Avoid mixing different application methods as far as possible.
Like all alkyd resin coatings, Interlac 665 has limited resistance to chemicals and solvents, and is not suitable for underwater equipment or locations with long-term contact with condensation.
Interlac 665 is not suitable for recoating over epoxy or polyurethane coatings, and must not be recoated over zinc-containing primers, because this may cause saponification of the alkyd resin and loss of adhesion.
For ideal appearance with brush and roller application, some colours may require two coats of Interlac 665 to achieve uniform hiding.
Using the Chromascan system, a wide range of colours can be produced.
In the United States, due to local transport regulations and local restrictions on the use of mineral spirits, the flash point of this product is 41 °C (106 °F). This has no effect on product performance.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Interlac 665 can only be recoated over alkyd or oil-based primers, such as Interprime 198. For other applicable primers, consult International Protective Coatings.
