Interthane 976 is a polyurethane coating used as a topcoat. Suitable for new construction and as a maintenance topcoat, and for use in various environments including offshore structures, petrochemical equipment, bridges and power plants. A two-component, fast-drying acrylic polyurethane topcoat with excellent resistance and long-term recoatability. When recoating after weathering or ageing, ensure the coating is thoroughly cleaned to remove all surface contaminants, such as oil, grease, crystalline salts and road grime, before applying subsequent Interthane 976 coats. Parameters on this page: dry film thickness 15–30 µm (0.6–1.2 mils), theoretical spreading rate 16 m²/L, number of components two-component.

All surfaces to be coated must be clean, dry and free of contaminants.
On steel substrates, Interthane 976 shall always be applied over the recommended anti-corrosive primer. The primer surface shall be dry and free from any contaminants. Interthane 976 must be applied within the specified recoat interval (refer to the relevant product data sheet).
Areas of damage and breakdown shall be prepared to the specified standard (e.g. Sa2½ (ISO 8501-1:2007) or SSPC-SP10 abrasive blast cleaning standard, or SSPC-SP11 power tool cleaning standard), and the primer shall be repaired before applying Interthane 976.
| 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. |

(1) Stir the base (Component A) with a power mixer.
(2) Mix all of the curing agent (Component B) with the base (Component A) and stir thoroughly with a power mixer.

|---|---|
| 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 interruptions, and other factors. |

All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
Gloss and surface smoothness depend on the application method. Mixing different application methods should be avoided where possible. Conventional air spray usually gives the optimum gloss and appearance.
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.
When recoating after weathering or ageing, ensure the coating is thoroughly cleaned to remove all surface contaminants, such as oil, grease, crystalline salts and road grime, before applying subsequent Interthane 976 coats.
When applying Interthane 976 in confined spaces, ensure adequate ventilation.
In accordance with good coating practice, application shall not proceed when environmental conditions deteriorate, e.g. when the temperature is below the dew point or moisture condensation is possible. Dehumidification, air conditioning and/or heating equipment may be required to control environmental conditions. Condensation on the surface during or after application will result in a matt surface and a poor-quality film.
Intercoat adhesion of coatings applied over aged Interthane 976 is somewhat lower than that over a new coating, but can still meet the requirements of the specified use.
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.
Interthane 976 can be applied directly over the following approved products: Interthane 870 Interthane 990
