Interdur 8863 Fluorocarbon Topcoat is a fluorocarbon coating used as a topcoat. These markets include bridges, sports venues, offshore platforms, oil depots, chemical and petrochemical plants, pulp and paper, the power industry, and common industrial and commercial steel structures where aesthetics are important. Compared with conventional catalysed acrylic and polyurethane topcoats, Interdur 8863 has excellent gloss and colour retention, significantly improving resistance to yellowing and chalking. Using other thinners, especially alcohol-containing thinners, can severely inhibit the curing mechanism of the coating. Parameters on this page: volume solids 53% ± 3% (depending on colour), dry film thickness 40-60 µm (1.6-2.4 mil), theoretical spreading rate 10.60 m²/L.

A high-performance, two-component fluorocarbon topcoat that, as part of a high-performance anticorrosive system, extends the service life of the coating before the first major repair. Compared with conventional catalysed acrylic and polyurethane topcoats, Interdur 8863 has excellent gloss and colour retention, significantly improving resistance to yellowing and chalking.
For market sectors with high visual and aesthetic requirements. These include bridges, stadiums, offshore platforms, oil depots, chemical and petrochemical plants, pulp and paper, the power industry, and general industrial and commercial steelwork where appearance is important.

All surfaces to be coated must be clean, dry and free from contamination. To ensure an ideal appearance, the primer or underlying coat should be sanded smooth and free from defects such as sags, dry spray or severe orange peel. Before application, all surfaces must be assessed and treated in accordance with GB 18839-2002.
Primed surfaces: Interdur 8863 is suitable for recommended anticorrosive paint surfaces; the primer surface must be dry and free from any contaminants. Interdur 8863 must be applied within the specified recoating interval (see the relevant product data sheet).
Damaged/broken areas should be prepared to the specified grade (e.g. blast to Sa 2.5 (GB 8923-1:1998) or SSPC SP11, power tool preparation), and the repair primer applied before applying Interdur 8863.

| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. |
Once mixed, paint should not be resealed. If work is interrupted for too long, mix a fresh batch for application.
| Cleaning | All equipment should be cleaned immediately after use with International thinner. Flushing spray equipment periodically during daily work is good practice. Cleaning frequency depends on the volume sprayed, temperature, spraying time, including delays, and other factors. |

All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
It is recommended to allow Interdur 8863 an induction time of 15 to 30 minutes after mixing before starting application.
When using metallic topcoats, a single application method should be used where possible, because different methods produce different aesthetic effects.
When recoating after weathering or ageing, before applying the subsequent Interdur 8863 coat, ensure the coating is thoroughly cleaned to remove all surface contaminants such as oil, grease, crystalline salts and road dust.
This product may be thinned only with the recommended International thinner. Other thinners, especially alcohol-containing thinners, severely inhibit the curing mechanism of the coating.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
When applying Interdur 8863 in confined spaces, ensure adequate ventilation.
Condensation during or immediately after application will result in a poor film.
This product is not recommended for immersion service. If severe chemical or solvent splashes are likely, contact International Paint for information on suitability.
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.
Interdur 8863 can be applied directly to the following approved products: Interdur 8801, Interdur 8815, Interdur 8840, Interdur 8860. For other suitable primers, consult International Paint.
