Bitumen Emulsion K1-40 is a cationic rapid-setting emulsion with a 40% bitumen content. It is commonly used for priming low-traffic roads, preparing surfaces for asphalt overlays, and dust control. The lower bitumen concentration in K1-40 allows for quicker penetration and drying, making it ideal for applications where a rapid, light coating is needed.  Petra Oil’s K1-40 emulsion meets British standard EN 13808, ensuring its suitability for a variety of preparatory tasks in road construction and maintenance.
