Intercure 384 High-build Intermediate Coat is an epoxy paint, used as an intermediate coat. The addition of lamellar micaceous iron oxide pigment enhances the barrier effect and improves the long-term overcoating performance of the coating system, making this material well suited for application in the fabrication shop before transport with final overcoating on site. A two-component, high-solids, low-VOC epoxy micaceous iron oxide intermediate coat with excellent barrier anti-corrosion performance, low-temperature curing and fast overcoating properties. The values may vary depending on colour differences and general production tolerances. Parameters on this page: dry film thickness 125–175 µm (5–7 mils), theoretical spreading rate 5.80 m²/L, number of components: two.

A two-component, high-solids, low-VOC epoxy micaceous iron oxide intermediate coat with excellent barrier anti-corrosion performance, low-temperature curing and fast overcoating properties.
Contains micaceous iron oxide and complies with BS 5493:1977.
As a high-build intermediate coat, part of a high-performance coating system, provides excellent barrier protection for aggressive environments (including offshore structures, bridges, chemical and petrochemical plants and power stations). The addition of lamellar micaceous iron oxide pigment enhances the barrier effect and improves the long-term overcoating performance of the coating system, making this material well suited for application in the fabrication shop before transport with final overcoating on site. The fast curing and overcoating properties of Intercure 384 provide production flexibility, making the product suitable both for newbuildings and for use as a maintenance coating on site.

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 8504:2000.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blast cleaning and application of Intercure 384, the surface shall be re-blasted to the specified visual standard.
Surface defects exposed by abrasive blasting must be ground, filled or treated by another suitable method.
Welds and damaged areas of shop-primed steel structures 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.
Zinc-primed substrates: before applying Intercure 384, ensure the primer surface is clean, dry and free of any contaminants and zinc salts. Before overcoating, ensure the zinc primer is fully cured.

|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International GTA822. 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 GTA822. 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.
Intercure 384 can cure below 0 °C (32 °F). However, this product should not be applied at 0 °C (32 °F) because there may be ice on the substrate.
This product shall be thinned only with the recommended International GTA220 thinner. Use of other thinners, particularly ketone-containing thinners, will severely inhibit curing of the coating.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
Excessive film thickness of Intercure 384 will extend the minimum overcoating time and handling time, adversely affecting long-term overcoating performance.
The intercoat adhesion to aged Intercure 384 is reduced compared with that to fresh coatings, but still meets the requirements of the intended use.
This product is generally used as a transport protection coating before on-site recoating. To ensure maximum recoatability, avoid over-application and keep the surface completely clean and free of contaminants, which may lodge in the profile because of the rough nature of the mica iron oxide pigment.
As with all epoxy paints, Intercure 384 will chalk and fade when exposed to the atmosphere. However, this does not affect anti-corrosion performance.
As with all products with a high micaceous iron oxide content, only darker colours can be formulated; therefore, when using thin-film topcoats in certain colours, two coats may be required to achieve good hiding.
Intercure 384 is not designed for continuous immersion in water.
This product holds the following specifications and approvals: • BS5493:1977 KUID & KF1F • UK Department of Transport, Project No. NO.122. Note: VOC values are typical and provided for guidance only. The value may vary with factors such as colour variation and normal production tolerances.
