Intergard 740 Epoxy Topcoat belongs to epoxy coatings and is used as a topcoat. It provides good abrasion resistance and protects against splashes of various chemicals, such as acids, alkalis, solvents and salt solutions. A two-component epoxy topcoat, applicable by brush, roller and spray. Although low molecular weight reactive additives become part of the film when cured under normal ambient conditions, they also affect the VOC value as determined by EPA Method 24 analysis. Parameters on this page: Volume Solids 51% ± 3% (depending on colour), Theoretical Spreading Rate 10.20 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.
Pre-primed surfaces Intergard 740 shall always be applied over the recommended anti-corrosive primer. The primer surface shall be dry and free from all contaminants. Intergard 740 must be applied within the specified overcoating interval (refer to the relevant product data sheet).
Areas with cracking, damage and other defects shall be prepared to the grade specified in the standard (for example: Sa2½ (ISO 8501-1:2007), SSPC SP6, or SSPC SP11) and the primer shall be repaired before application of Intergard 740.
Concrete, precast elements and other substrates.
Intergard 740 is suitable for application on concrete. The first coat of Intergard 740 is recommended to be thinned 10–15% with International thinner to provide good penetration on concrete substrates and to serve 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.
Gypsum, cement, concrete and other substrates.
The surface shall be clean, dry and free from all contaminants. Remove loose or flaking old paint. Fill and sand minor defects.
Damp spots, oil stains, bitumen exudates, nicotine deposits, weathering products and rust stains must be removed in situ, or preferably the cause of these contaminants/defects eliminated. Before application commences, viable mould, algae and other growths must be removed. Household-strength bleach diluted with water to 1:4 or a proprietary fungicidal solution shall be used. Two treatments may be required; after treatment, the surface must be rinsed with water and residues removed. To prevent future biological attack, the conditions supporting the survival of these organisms shall be identified and effective preventive measures established.

|---|---|
| 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 of paint 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.
When Intergard 740 is applied 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).
As with all epoxy paints, the product will chalk and fade on exposure to the atmosphere. The rate of chalking depends on the environment, but this has no adverse effect on the anti-corrosive performance, with only a thin surface layer chalking.
Condensation on the surface during or after application will cause loss of gloss and a poor-quality film.
Premature exposure to standing water may cause colour change, especially for dark colours.
Gloss and surface evenness depend on the application method. Avoid mixing different application methods as far as possible.
Over-application of Intergard 740 will extend the minimum overcoating time and handling time, adversely affecting long-term overcoating performance.
For ideal appearance by brush and roller application, two coats of Intergard 740 may be required for certain colours to achieve uniform coverage.
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.
