- Applications
- Recommended use
- As a high-build one-coat system in compliance with the VOC provisions for protecting steel structures in a moderately corrosive environment. May be used as an undercoated intermediate coat or topcoat within the system.
- Drying and overcoating
Product compatibility
Previous coat: According to Hempel’s Specification. Recommended product is: Hempadur 47140
Subsequent coat: None.
Drying timeSurface temperature 20°C Hard dry 3 hours Drying conditions
- To obtain the drying time stated, it is important to maintain sufficient ventilation during application, drying and curing.
- Condensation on the freshly applied coating should be avoided.
Overcoating details
- The surface must be dry and clean prior to application.
Other remarks
- Hempel’s Specification supersedes any recommendations given in the Product Data Sheets.
