KOREPOX EH4200 is a two-component polyamide-cured epoxy resin-based high-build coating, suitable for heavy steel structures, with good water resistance and excellent corrosion resistance.
As a high-build primer or intermediate coat and topcoat, used on bridges and general steel structures; for outdoor steel structures, a polyurethane topcoat is recommended.
| Appearance and colour | Flat, grey |

| density | Mixture, approx. 1.3–1.5 depending on colour |
| Volume Solids | Approx. 70% (measured according to ISO 3233) |
| Theoretical Spreading Rate | 7.0 m²/L on smooth surfaces at a dry film thickness of 100 µm |
| Flash Point | Base (EH4200PTA): 26 °C (closed cup); hardener (EH4200PTB): 26 °C (closed cup) |
Before application, remove all oil, grease, dust and other contaminants from the surface. * Steel: blast clean to Sa 2.5 or clean with power tools to St 3.
KOREPOX HOLDING PRIMER EP170QD, EP1700, GALVANY shop primer IZ182 or according to coating specification.
Spray (air and airless). Airless spray: nozzle size 483–787 µm (0.019–0.031 in); spray pressure 11.7–15.2 MPa; spray angle 60°.
Base (EH4200PTA) : Hardener (EH4200PTB) = 4 : 1 (by volume). Before application, mix the two components completely according to the specified ratio.
Thinner No. 024, 024E. Do not thin the two components separately; only the mixture may be thinned.
The substrate must be clean and dry; the ambient temperature during application and curing should be 10–40 °C. To prevent moisture condensation, the substrate surface temperature should be above the dew point by 3 °C. Application is prohibited when relative humidity exceeds 85%.
1 coat: dry film thickness 100 µm. The film thickness can be adjusted according to the purpose and location of application.
| Substrate temperature | 5°C | 20°C | 30°C |

At 20 °C, 3 h.
At 20 °C, minimum 10 hours, maximum none. Long-term exposure causes chalking; even within the overcoating interval, remove chalking and foreign matter before recoating.
Continuous: 93 °C/200 °F (non-immersion areas); intermittent: 121 °C/250 °F (non-immersion areas).
