Intergard 276 Post-blast Protection Primer is an epoxy paint, used as a primer. Also used as a tie coat over zinc silicate coatings to prevent zinc salt formation on aged coatings and pinholes on subsequent high-build topcoats. Can be overcoated after prolonged ageing. When coating steel at high ambient temperatures, thinning with International thinner may be required to prevent dry spray and control film thickness. This product cannot cure adequately at temperatures below 5 °C (41 °F). Parameters on this page: dry film thickness 25–40 µm (1–1.6 mils), theoretical spreading rate 11.80 m²/L, number of components: two.

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: for immersion use, Intergard 276 must be applied over surfaces blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC SP10. However, for atmospheric exposure, Intergard 276 should be applied over surfaces blasted to Sa 2½ (ISO 8501-1:2007) or at least SSPC SP6.
Surface defects exposed by blast cleaning must be ground, filled or treated by a suitable method.
Ultra-high-pressure water jetting (for non-immersion use only) may be applied over surfaces prepared to Sa2 (ISO 8501-1:2007) or SSPC SP6, with light rust allowed to a standard not lower than HB2M (see the International Paint hydroblasting standard). For more information, contact International Paint.
Application as a tie coat (see product characteristics): if a zinc primer is used, remove weld spatter, grind welds and sharp edges where required, and blast clean welds and damaged primer to Sa 2½ (ISO 8501-1:2007) or SSPC SP6. Shop primer or other primer surfaces should be dry and free of any contaminants (oil, grease, salt, etc.), and overcoated with Intergard 276 within the specified primer overcoating interval (see the relevant data sheet).
Before overcoating, ensure the zinc dust primer is fully cured, and clean, dry and free from zinc salts.

| 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.
Use as a temporary protection primer: Intergard 276 is suitable as a temporary post-blast protection primer for steel structures in immersed and atmospheric environments. Apply Intergard 276 to the recommended thickness, as over-thick application produces a glossy surface unsuitable for overcoating after ageing.
When coating steel at high ambient temperatures, thinning with International thinner may be required to prevent dry spray and control 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).
Intergard 276 is also suitable for application over degreased and abraded stainless steel and galvanized steel. Light blasting with non-metallic abrasive can be used for abrading; for small areas, an emery wheel can be used. As a tie coat: to ensure good penetration of the zinc silicate coating, Intergard 276 should be thinned 15–25% with International thinner. Intergard 276 should cure before applying high-build topcoats, otherwise the effectiveness in preventing pinholes will be reduced.
Avoid excessive film thickness, otherwise cracking may occur when recoated with a high-build coating.
For application below 10 °C (50 °F), other tie coats are available. Contact International Paint for information.
For marine environments, the system and recoat intervals may differ.
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 276 is suitable for application over the following primers: Interzinc 22; Interzinc 52. The following topcoats/intermediate coats are recommended for use with Intergard 276:
| Intercure 200HS | Intergard 740 |
|---|---|
| Intercure 420 | Interseal 670HS |
| Interfine 629HS | Interthane 870 |
| Interfine 878 | Interthane 990 |
| Interfine 979 | Interzone 505 |
| Intergard 251 | Interzone 954 |
