Interdur 8862 Acrylic Polysiloxane Topcoat is an acrylic paint, used as a topcoat. Suitable for newbuilding and maintenance projects in a variety of environments. A low-VOC, high-performance, two-component, isocyanate-free acrylic topcoat with excellent weather resistance and long-term overcoating performance. Although the low-molecular-weight reactive co-reactant becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 has shown that it also affects the VOC value. Parameters on this page: volume solids 64% ± 2%, dry film thickness 50–75 µm (2–3 mils), theoretical spreading rate 12.80 m²/L.

¹ See the "Definitions and Abbreviations" section of International Paint's Protective Coatings division. ² Sufficient film strength has been achieved to allow handling and treatment of the coated steel structure.
Drying time is affected by relative humidity. The higher the relative humidity, the faster the drying. The quoted drying times were measured at the specified temperature and 50% relative humidity. The drying time data at 10 °C (50 °F) was measured at 80% relative humidity.

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.
Primed surfaces: Interdur 8862 should always be applied over a recommended anti-corrosive primer. The primer surface should be dry and free of contamination, and Interdur 8862 must be applied within the specified overcoating interval (see the relevant product data sheet).
Areas of spalling and damage etc. shall be treated to the specified standard (e.g. Sa 2½ (ISO 8501-1:2007) or SSPC-SP6 blast cleaning, or SSPC-SP11 manual/power tool cleaning), and these areas touched up with primer before applying Interdur 8862.
| Mixing | This product is supplied in two containers forming one unit. Mix the two components in the specified ratio in one operation. Once mixed, use within the specified pot life. |

|---|---|
| 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.
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.
Apply in good weather conditions. The surface to be coated must be at least 3 °C (5 °F) above the dew point; below 10 °C (50 °F), the product will not cure adequately.
When applying Interdur 8862 in confined spaces, ensure adequate ventilation.
Interdur 8862 reacts with atmospheric moisture, so the cans should be kept closed at all times. If the cans are left open, the paint will skin and lose its pot life. Partial mixing is not recommended.
Condensation on the surface during or after application will cause loss of gloss and a poor-quality film.
Premature exposure to standing water may cause colour change, especially for dark colours and at low temperatures.
Interdur 8862 is not suitable for immersion.
Thinning may adversely affect film appearance and performance; consult International Paint for further advice.
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 are suitable for Interdur 8862:
| Intercure 200 | Intergard 251HS |
|---|---|
| Intercure 200HS | Intergard 475HS |
| Intercure 420 | Interplus 356 |
