Interfine 2700 Epoxy Polysiloxane is an epoxy coating. Its anticorrosive protection performance is comparable to that of conventional epoxy intermediate coats; Interfine 2700 can reduce the scheme complexity of high-performance multi-coat systems, thereby saving cost and improving application efficiency. The product combines the excellent gloss retention of typical polyurethane topcoats with the corrosion resistance, chemical resistance and abrasion resistance demonstrated by conventional epoxy technology. When applying Interfine 2700 by brush or roller, multiple coats are necessary to achieve the specified total dry film thickness of the system. Parameters on this page: volume solids 86% ± 3% (depending on colour), dry film thickness 76-178 µm (3-7.1 mil), theoretical spreading rate 6.88 m²/L.

An isocyanate-free epoxy-modified polysiloxane.
The product combines the excellent gloss retention of typical polyurethane topcoats with the corrosion resistance, chemical resistance and abrasion resistance demonstrated by conventional epoxy technology.
Interfine 2700 is a member of International's premium polysiloxane topcoat series. It is designed to provide excellent colour and gloss retention and, when used as part of a high-performance anticorrosive system, to extend the time to first maintenance. Interfine 2700 is suitable for market areas where visual effect is critical and high decorative standards are required. These areas include high-performance structures such as bridges, offshore structures and tank farms, as well as general industrial and commercial steel structures with high decorative requirements.
Interfine 2700 combines both anticorrosive protection and excellent aesthetics. Its anticorrosive protection performance is comparable to that of conventional epoxy intermediate coats; Interfine 2700 can reduce the scheme complexity of high-performance multi-coat systems, thereby saving cost and improving application efficiency. Interfine 2700 can also be applied directly to metal surfaces (some usage limitations exist; consult your local representative for more information).

All surfaces to be coated must be clean, dry and free from contaminants. Before coating, all surfaces must be assessed and treated in accordance with ISO 8504:2000. Can be applied directly to metal surfaces. Surface preparation to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. Before application, the surface must achieve the specified cleanliness.
| A sharp-angle profile of maximum 25-50 µm (maximum 1-2 mil) is recommended. | Surface defects exposed during blasting must be ground, filled or treated by a suitable method. |
|---|
Primed surfaces: Interfine 2700 should always be applied over a recommended anticorrosive coating scheme. The primer surface must be dry and free from any contamination, and Interfine 2700 must be applied within the specified recoating interval (see the relevant product data sheet).
Damaged or broken areas should be prepared to the specified standard (e.g. Sa 2½ (ISO 8501-1:2007) or SSPC-SP6, blasting, or SSPC-SP11, power tool cleaning), and the primer repaired before applying Interfine 2700.

|---|---|
| Interruption of work | Do not let coating remain in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International GTA415. All unused coating should be stored in sealed containers. After storage, partially filled containers may show surface skinning and/or increased viscosity. Filter the coating before use. |
| Cleaning | Clean all equipment with International GTA415 immediately after use. |
Periodic flushing of spray equipment during application is also recommended. Cleaning frequency depends on spray volume, temperature and time, including all interruption periods.
Surplus paint and empty containers must be disposed of in accordance with the relevant local regulations.
The gloss level of the topcoat depends on the application method. Avoid mixed application methods. The optimum gloss and appearance are always obtained by conventional air spray.
When applying Interfine 2700 by brush or roller, multiple coats are necessary to achieve the specified total dry film thickness of the system.
The product shall be thinned only with the recommended International GTA007 thinner. Use of other thinners, particularly alcohol- and ketone-containing thinners, will severely retard curing of the coating.
Never apply beyond the pot life, even if the coating may still appear liquid and usable. Failure to comply will result in reduced coating performance.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
As with all polysiloxane coatings, care must be taken when applying multiple coats of Interfine 2700 to ensure the applied wet film is continuous and the dry film thickness is at least 100 µm (4 mil). Otherwise, pinholes may result, affecting the final appearance and performance.
For direct-to-metal applications, stripe coating should be carried out to ensure good edge protection.
When applying Interfine 2700 in confined spaces, ensure adequate ventilation.
Interfine 2700 achieves satisfactory curing results at a relative humidity between 40% and 85%. Curing is slower at low humidity and faster at high humidity.
Condensation on the surface during or after application will cause loss of gloss and a poor-quality film.
When applying over aged coatings, ensure the aged coating is thoroughly cleaned to remove all surface contaminants such as oil, grease and salts before applying the next coat of Interfine 2700.
Premature exposure to standing water may cause colour change, especially for dark colours and at low temperatures.
The intercoat adhesion on aged Interfine 2700 is reduced relative to that on a fresh coating, but still meets the needs of the intended use.
This product is not recommended for immersion service. If severe chemical or solvent splashes are likely, contact International Paint for information on suitability.

See the drying times cited in the "Definitions and Abbreviations" of International Paint Industrial Coatings, measured at the specified temperature and 50% relative humidity.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
The following primers/intermediate coats are recommended for Interfine 2700: Cathacoat 302H, Intergard 2575, Interzinc 22, Interzinc 52. For other suitable primers/intermediate coats, consult International Paint Industrial Coatings.
Interfine 2700 must absolutely not be applied directly over Interzinc 52 cured with a low-temperature curing agent.
The maximum recoating interval of Interfine 2700 depends on the primer.
Interfine 2700 can only be recoated with itself.
