Hempel Hempadur 4774D is a self-priming, two-component, high-build, pure epoxy paint, polyamide / amine cured. Abrasion and corrosion resistant.
Hempel Hempadur 4774D is best used as a high build primer, intermediate and/or self-primed finish for high performance, heavy-duty coating systems.
New steel: Abrasive blasting to min. Sa 2½ (ISO 8501-1:2007). For temporary protection, if required, use a suitable shop primer. All damage of shop primer and contamination from storage and fabrication should be thoroughly cleaned prior to final painting. Welds, rusty spots, etc. to be abrasive spot-blasted.
Stainless steel: To be abrasive blasted to a uniform, sharp, dense profile, ISO Comparator Medium (G), corresponding to Rz minimum 50 micron. Any salts, grease, oil, etc. to be removed before abrasive blasting is commenced.
Repair: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to St 3 (ISO 8501-1:2007) (minor areas) or by abrasive blasting to min. Sa 2, preferably to Sa2½ (ISO 8501-1:2007). Improved surface preparation will improve the performance of the product.
Use only where application and curing can proceed at temperatures between: 5°C/41°F - 60°C/140°F. The temperature of the paint itself should be above: 15°C/59°F. Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. In confined spaces provide adequate ventilation during application and drying. Maximum relative humidity: 85%.
Can be used on top of zinc silicate or on metallised area by use of the flash coat technique.
