Intercure 4500 Polyaspartic Topcoat is a topcoat. Fast curing at low temperature and early hardness development make Intercure 4500 suitable for shop fabrication, reducing heating costs and improving production efficiency for facilities in cold climates. Based on polyaspartic resin technology, with standard application equipment, Intercure 4500 can be applied directly to metal surfaces or suitable primers in one coat for more severe corrosion environments. Apply by air spray; to achieve maximum film thickness, apply in multiple cross passes. Parameters on this page: volume solids 77% ± 2%, dry film thickness 150–250 µm (6–10 mil), theoretical spreading rate 4.40 m²/L.

Intercure 4500 is a low-VOC, high-solids, fast-drying primer/topcoat providing excellent corrosion protection and long-term ageing resistance. Based on polyaspartic resin technology, with standard application equipment, Intercure 4500 can be applied directly to metal surfaces
| or suitable primers in one coat for more severe corrosion environments. | Replacing alternative two- or three-coat systems, Intercure 4500 provides corrosion protection and decorative effect with fewer coats. The fast-drying characteristic (even at low temperature) helps optimise application time and reduce labour costs. |

Fast curing at low temperature and early hardness development make Intercure 4500 suitable for shop fabrication, reducing heating costs and improving production efficiency for facilities in cold climates. Intercure 4500 provides great benefits for OEM plants where production and process efficiency are important.

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.
Steel substrates: blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blasting and application of Intercure 4500, 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.
Recommended angular surface profile of 50–75 µm (2–3 mils).
Before applying Intercure 4500, damaged areas shall be prepared to the specified standard (e.g. Sa 2½ (ISO 8501-1:2007) or SSPC SP6 blast).

|---|---|
| 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.
Obtain the detailed Intercure 4500 application guide before use.
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 Intercure 4500 by brush or roller, multiple coats are necessary to achieve the specified total system dry film thickness.
Apply in good weather. The surface temperature to be coated must be at least 3 °C (5 °F) above the dew point. Application at excessive relative humidity or in condensation-prone environments may cause immediate or premature loss of gloss.
Relative humidity during application and curing is recommended not to exceed 85%. Application in environments above 50% relative humidity may accelerate drying.
Apply with care; the dry film thickness should not exceed 350 µm (14 mil).
Film thickness above the recommendation causes high gloss.
When applying Intercure 4500 in confined spaces, ensure adequate ventilation.
As with other fast-drying paint systems, take care to avoid overspray contamination of previously coated members.
Intercure 4500 is not designed for continuous immersion in water.
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.
Intercure 4500 may be applied directly to metal surfaces in environments up to and including C4 (ISO 12944 Part 2). However, in C4 environments with high or very high durability requirements, a matching primer is required, and in C5 environments the recommended primer must be used. Suitable primers for ISO 12944 C4 environments: Intercure 200HS. Suitable primers for ISO 12944 C5 environments: Interzinc 52. Intercure 4500 is normally not overcoated with other topcoats, except by self-overcoating.
