Intergard 345 Epoxy is an epoxy coating. Suitable for use as a one- or two-coat primer/topcoat, or as an intermediate coat applied over the recommended anticorrosive primer. A two-component, low-VOC, high-solids, fast-curing epoxy primer/topcoat containing zinc phosphate anticorrosive pigment. However, in non-aggressive low-corrosion environments, for example a C2 environment as defined in ISO 12944 Part 2, a single coat of Intergard 345 at 80 µm (3.2 mil) dry film thickness is acceptable. Parameters on this page: dry film thickness 100-150 µm (4-6 mil), theoretical spreading rate 5.60 m²/L, number of components: two-component.

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.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Blast cleaning: blast clean steel surfaces to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between blast cleaning and application of Intergard 345, the surface must be re-blasted to the specified visual standard.
Surface defects exposed by blast cleaning should be ground, filled or treated by a suitable method. The recommended surface roughness is 50-75 µm (2-3 mil). Intergard 345 is suitable for application to blast-cleaned surfaces that originally met the above standard but have been allowed to weather under good shop conditions for 7-10 days. The surface then degrades to Sa 2, but must be free from loose powdery deposits.
Primed surfaces: welds and damaged areas must be blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC SP6.
If the shop primer shows large-scale breakdown, the entire area must be blast cleaned.
Concrete, precast elements, etc.: Intergard 345 is suitable for application to concrete. It is recommended that the first coat of Intergard 345 be thinned 10-15% with International thinner to provide good penetration on the concrete substrate and act as a primer/sealer coat.
Before applying the coating, concrete shall be cured for at least 28 days. The moisture content of the concrete shall be below 6%. All surfaces shall be clean and dry and free from curing compounds, release agents, smoothing compounds, surface hardeners, efflorescence, grease, oil, dirt, old coatings and loose or disintegrating concrete. All cast or precast concrete shall also be treated by brush-off blast cleaning or acid etching to remove laitance.

| Thinner | International GTA220 | Normally no thinning is required. |
(International GTA415). In extreme cases, consult the local technical representative.
Do not thin beyond the requirements of local environmental regulations.
| 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. |
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.
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 345 by brush or roller, multiple coats are necessary to achieve the specified total system dry film thickness.
This product does not cure adequately below 5 °C (41 °F). For optimum performance, curing should take place above 10 °C (50 °F).
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
When applying Intergard 345 in confined spaces, ensure adequate ventilation.
In moderately corrosive environments, a minimum dry film thickness of 100 µm (4 mil) is recommended to ensure adequate anticorrosive performance. However, in non-aggressive low-corrosion environments, for example a C2 environment as defined in ISO 12944 Part 2, a single coat of Intergard 345 at 80 µm (3.2 mil) dry film thickness is acceptable.
Condensation on the surface during or after application will cause loss of gloss and a poor-quality film.
For certain colours, particularly dark colours formulated through the Chromascan tinting system that require large amounts of pigment, the drying time and recoating interval must be extended. Consult International for details.
Exposure to mist or rain before the specified hard-dry time will damage the surface appearance and then impair overall performance. This is particularly noticeable in dark-coloured coatings.
As with all epoxy coatings, Intergard 345 will chalk and fade on exposure to the atmosphere. However, this does not affect its anticorrosive performance.
For durable decorative surfaces requiring good gloss and colour retention, overcoat with the recommended topcoat.
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.
Intergard 345 is normally applied directly to blast-cleaned steel, but it can also be applied directly over the following primers: Intercure 200HS, Intercure 200, Intergard 251, Intergard 269, Intergard 345, Interzinc 52, Interzinc 315. The following topcoats are recommended for use with Intergard 345: Interfine 629HS, Intergard 740, Interthane 870, Interthane 990. For other suitable primers/topcoats, consult International.
