Intershield 300 Abrasion Resistant Aluminium Pure Epoxy belongs to Epoxy. As a primer, it is highly suitable for relevant areas of offshore platforms and floating production and storage facilities, such as underwater hulls, ship hulls, external superstructures, decks and cargo holds. A two-component, abrasion-resistant pure epoxy aluminium-containing coating with durable anti-corrosive performance. Although low molecular weight reactive additives become part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that they also affect the VOC value. Parameters on this page: volume solids 60% ± 2%, dry film thickness 100–200 µm (4–8 mil), theoretical spreading rate 4 m²/L.

All surfaces to be coated shall be clean, dry and free from contamination. Before application, all surfaces shall be assessed and prepared in accordance with ISO 8504:2019. Oil and grease shall be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Abrasive blasting: For immersion service, Intershield 300 must be applied to surfaces blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC SP10. However, for atmospheric exposure, Intershield 300 should be applied to surfaces blast cleaned to Sa2½ (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.
Recommended surface roughness 50–75 µm (2–3 mils).
Ultra-high pressure water jetting/wet abrasive blasting: Can be applied to surfaces prepared to Sa2 (ISO 8501-1:2007) or SSPC SP6, with flash rust on the surface not exceeding grade HB2M (refer to International high-pressure water jetting standard) or grade SB2M (refer to International wet abrasive blasting standard).
Areas of steel structures with shop primer that are ruptured, damaged, or at welds shall be prepared to the specified standard (e.g. Sa2½ (ISO 8501-1:2007) or SSPC SP10, or power tool cleaned to Pt3 (JSRA SPSS:1984) or SSPC SP11). Intact, approved shop-primed surfaces must be clean, dry, free of soluble salts and any other surface contaminants. Unapproved shop primer shall be completely removed by abrasive blasting, with the surface cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP10. In some cases, sweep blasting to the specified International standard (e.g. AS2 or AS3) may be permitted.

| Roller application | Typical thickness 50–75 µm (2.0–3.0 mils) | |
| Thinner | International GTA220 | Normally no thinning is required. |
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. |
|---|
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
Apply by airless spray only. Other methods such as brush or roller may require more than one coat and are recommended only for small areas or touch-up.
This product must be thinned only with the recommended International thinner. Other thinners, especially those containing ketones, severely inhibit the curing of the coating.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point. When applying Intershield 300 in confined spaces, ensure adequate ventilation.
Like all epoxy coatings, Intershield 300 will chalk and fade when exposed to the atmosphere. However, this phenomenon will not affect anticorrosive performance. Where a durable decorative finish with good gloss retention and colour retention is required, overcoat with the recommended topcoat. Over-application of Intershield 300 will extend the minimum recoating time and handling time, adversely affecting long-term recoating performance.
Where necessary, Intershield 300 should be washed with high-pressure water and/or solvent cleaned before overcoating to ensure any surface contamination is removed.
At some locations worldwide, the product can be applied at substrate temperatures from -20 °C to -5 °C. However, if recoating at low temperature, consideration should be given to the possibility that the remainder of the coating system may require a higher temperature for full cure.
