Intergard 475HS Epoxy is an epoxy coating. As a high-build epoxy coating for various environments, such as offshore structures, petrochemical plants, paper mills and bridges, enhancing the barrier protection of various anti-corrosion coating systems. Available with conventional pigments, or with micaceous iron oxide pigment to enhance overcoating performance. Although the low-molecular-weight reactive additive becomes part of the film on curing under normal ambient conditions, EPA Method 24 analysis shows that it also affects the VOC value.

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 8504:2019.
Primed surfaces: Intergard 475HS shall always be applied over the recommended anticorrosive primer. The primer surface shall be dry and free from any contaminants; Intergard 475HS must be applied within the specified recoat interval (refer to the relevant product data sheet).
Cracked, damaged and similar areas shall be prepared to the grade specified in the standard (e.g. Sa 2½ (ISO 8501-1:2007), SSPC SP6, or SSPC SP11) and the primer repaired before applying Intergard 475HS.
Zinc-primed substrates: before applying Intergard 475HS, ensure the primer surface is clean, dry and free from contaminants and zinc salts. Before overcoating, ensure the zinc primer is fully cured.

In extreme cases, consult the local technical representative.

| Cleaner | Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations. |
|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. 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. |
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
Intergard 475HS acts mainly as a high-build barrier coating, providing barrier protection for the system. Where appearance is particularly important, overcoating with a durable topcoat of the Interfine or Interthane series is recommended.
Apply by airless spray to achieve the maximum film thickness per coat. Application methods other than airless spray cannot achieve the required film thickness. With air spray, several cross coats are required to achieve the maximum film thickness. At low or high temperatures, special application techniques may be required to achieve the maximum film thickness.
When applying Intergard 475HS by brush or roller, multiple coats are necessary to achieve the specified total system dry film thickness.
The surface temperature shall always be at least 3 °C (5 °F) above the dew point. When applying Intergard 475HS in confined spaces, ensure adequate ventilation. Unacceptable low temperature and/or high humidity during or immediately after application cause incomplete curing and surface contamination, jeopardising intercoat adhesion.
At curing temperatures above 25 °C (77 °F), another curing agent may be used.
Recommended topcoat overcoating interval
| Temperature | Surface Dry | Hard Dry | Minimum | Maximum |
| 25°C (77°F) | 90 min | 6 h | Unlimited * | |
| 40°C (104°F) | 60 min | 2 h | Unlimited * | |
* See the "Definitions and Abbreviations" of International Paint's Industrial Protective Coatings division. When applied on specific structures, alternating between standard and high-temperature curing agents causes noticeable colour change, due to yellowing and fading of the epoxy resin under ultraviolet light. As with all epoxy coatings, Intergard 475HS chalks and fades on exposure to the atmosphere. This does not affect anti-corrosion performance.
Intergard 475HS is not designed for continuous immersion in water.
The micaceous iron oxide version of this product is often used as a 'transport protection coating' before on-site overcoating. To extend the overcoating interval, do not apply too thickly and avoid over-application; the surface shall be completely clean and free from contamination, as contaminants may lodge in the surface texture due to the rough nature of the micaceous iron oxide pigment.
When applying Intergard 475HS at temperatures below 15 °C (59 °F) or at wet film thickness of 150 µm (6 mil) or less, adding about 5% International GTA007 thinner improves film appearance and sprayability and helps control film thickness.
After consulting the International Paint Protective Coatings division, this paint may be applied by other methods such as flow coating.
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.

| Intercure 200 | Interzinc 22 *(a mist coat or tie coat may be required) |
|---|---|
| Intergard 251 | Interzinc 315 |
| Intergard 251HS | Interzinc 52 |
| Intergard 269 | Interzinc 52E, Interzinc 2280 *(a mist coat or tie coat may be required). Suitable topcoats are: |
