PPG Sigma EP 111 Primer has been formulated for use on steel and concrete, offers exceptional rust preventing properties in environments exposed to large levels of water and moisture
PPG Sigma EP 111 Primer is a two component, high solids, polyamide, zinc phosphate, epoxy primer designed for general purpose use on steel and concrete structures exposed to adverse weather conditions. Sigma EP 111 Primer is compatible with most two component and conventional coatings even after long weathering periods. Highways Agency Number Item No.111
PPG Sigma EP 111 Primer is highly protective to corrosion damage and works well in industrial and coastal environments to protect the substrate against the ongoing effects of weather. Sigma EP 111 Primer offers toughness, and flexibility and adheres particularly well to steel.
PPG Sigma EP 111 Primer should be applied using brush or airless spray and can even be applied at low conditions down to -5°C, for application where warm ventilation is not feasibly possible. Where conditions are of around 20°C then you will be provide with a touch dry surface after 4 hours ready for recoating after 8 hours.
