What is Interlac 665 and why choose it?
Interlac 665 by International Marina is a single component alkyd gloss enamel finish designed as an economical, easy-to-maintain topcoat for industrial and marine environments. It delivers a high gloss cosmetic finish on suitably primed steel surfaces, providing attractive appearance and straightforward maintenance for both interior and exterior areas above the waterline or in industrial facilities.
This coating is suitable for professional and industrial use where a single pack, brush-roller-spray applicable finish is required, especially in maintenance work on offshore structures, petrochemical and chemical plants, and general steelwork protected with compatible alkyd or oleoresinous primers.
Main features
- Single pack alkyd enamel: One component product, easy to mix and apply on site with no curing agent required.
- High gloss finish: Provides a high sheen cosmetic topcoat for alkyd-based systems, improving appearance and visibility of coated structures.
- Interior and exterior use: Intended as a finish coat for both indoor and outdoor exposure where chemical attack is limited.
- Maintenance-focused formulation: Designed primarily for site application and maintenance painting on existing compatible systems.
- Good application versatility: Can be applied by airless spray, conventional air spray, brush or roller.
- Wide colour availability: Offered in a wide range of colours via the Chromascan system, including standard shades such as white, black, red, signal green, storm grey and others (depending on version).
- Optimised film build: Typical dry film thickness of 40–50 microns (1.6–2 mils) for efficient coverage and appearance.
- Compatible with alkyd/oleoresinous primers: Recommended for use over alkyd or oleoresinous anticorrosive priming systems such as Interprime 198.

Drying and overcoating information (typical)
At 40–50 microns DFT, good ventilation:
- 10°C (50°F): Touch dry ~14 hours; hard dry ~48 hours; minimum overcoating interval 24 hours (extended maximum).
- 15°C (59°F): Touch dry ~10 hours; hard dry ~36 hours; minimum overcoating interval 24 hours (extended maximum).
- 25°C (77°F): Touch dry ~6 hours; hard dry ~24 hours; minimum overcoating interval 24 hours (extended maximum).
- 40°C (104°F): Touch dry ~4 hours; hard dry ~8 hours; minimum overcoating interval 14 hours (extended maximum).
Overcoating intervals are guidance only and may vary with local climate and conditions.
Application guidance
- Mixing: As a one component coating, the product must be mixed thoroughly with a power agitator before application.
- Airless spray: Recommended; typical tip range 0.33–0.48 mm (13–19 thou) with a minimum fluid pressure of approximately 141 kg/cm² (around 2005–2010 psi).
- Conventional air spray: Recommended using suitable equipment; thinning with GTA004 may be required.
- Brush / roller: Suitable; typically 25–40 microns (1.0–1.6 mils) DFT per coat can be achieved. In some colours two coats may be needed for full opacity and uniform gloss.
- Environmental conditions: Apply in good weather with the steel temperature at least 3°C above the dew point.
- Storage: Shelf life minimum 24 months at 25°C, stored in dry, shaded conditions away from heat and ignition, subject to re-inspection thereafter.
Applications and use cases
- Industrial maintenance coating for steel and suitably primed surfaces in environments including offshore installations, petrochemical plants and chemical plants, where chemical exposure is limited.
- Economical single pack finish coat in areas that do not require high chemical or solvent resistance but do need a durable cosmetic topcoat.
- Cosmetic finish for alkyd-based systems intended for both interior and exterior exposure.
- On-site maintenance painting: Product is designed primarily for site application rather than factory airless application, helping maintenance teams refurbish existing compatible alkyd systems.
Limitations of use: Interlac 665 is not suitable for immersed areas or for conditions of continuous condensation and is not designed for application over epoxies, polyurethanes or zinc-rich primers.
FAQ
1. Is Interlac 665 a single component or two component coating?
Interlac 665 is a single component (one pack) alkyd gloss enamel. No separate curing agent is required.
2. Can Interlac 665 be used on immersed surfaces or in constant condensation?
No. The product is not suitable for immersion service or continuous condensation conditions.
3. What kind of primers can Interlac 665 be applied over?
It is suitable only over alkyd or oleoresinous priming systems, for example Interprime 198. It should not be applied over epoxies, polyurethanes or zinc-based primers.
4. Which application methods are recommended?
The coating can be applied by airless spray, conventional air spray, brush or roller, using International GTA004 as thinner when required and permitted by local regulations.

Personal protective measures (Section 8)
Interlac 665 is a solvent-borne product for professional and industrial use. Appropriate personal protection and engineering controls must be in place during application and handling.
Engineering controls and hygiene
- Use only with adequate ventilation, employing process enclosures and local exhaust ventilation to keep airborne concentrations below occupational limits and below the lower explosion limit.
- Use explosion-proof ventilation and electrical equipment where required.
- Wash hands, forearms and face thoroughly after handling and before eating, drinking or smoking. Remove contaminated clothing before entering eating areas and wash before reuse.
Eye and face protection
- Wear safety eyewear complying with an approved standard when there is a risk of exposure to splashes, mists or vapour.
- Recommended protection where contact may occur: safety glasses with side shields.
Hand protection
- Use chemical-resistant, impervious gloves compliant with relevant standards when handling the product.
- For prolonged or frequently repeated contact, gloves with protection class 6 (breakthrough time > 480 minutes according to EN374) are recommended; for example Viton or nitrile gloves with minimum thickness around 0.38 mm.
- For brief contact, gloves with protection class 2 or higher (breakthrough time > 30 minutes according to EN374) are recommended; for example nitrile gloves with minimum thickness around 0.12 mm.
- Replace gloves regularly and whenever signs of damage or degradation are observed.
Body and skin protection
- Wear protective clothing selected according to the task and associated risks, approved by a specialist prior to use.
- Where there is a risk of ignition from static electricity, use anti-static protective clothing including coveralls, boots and gloves in accordance with EN 1149.
- Use appropriate protective footwear and additional skin protection as required.
Respiratory protection
- When ventilation is inadequate or exposure limits may be exceeded, wear a respirator conforming to EN140 with type A/P2 filter or better, as part of a full respiratory protection program.
- Dry sanding, flame cutting and welding of the dry paint film will generate dust and/or hazardous fumes; wet sanding/flatting is preferred. Where exposure cannot be controlled by local exhaust, use suitable respiratory protection.
Environmental exposure control
- Check emissions from ventilation or process equipment to ensure compliance with environmental legislation.
- Where necessary, use fume scrubbers, filters or modify process equipment to reduce emissions.
