K1-70
K1-70 is a cationic, rapid-setting bitumen emulsion with a minimum binder content of 70%. It breaks quickly on contact with aggregate, so roads can reopen fast. No heating is needed on site, which cuts fuel costs and emissions.
Where K1-70 is used
Bitumen emulsion is fine droplets of bitumen dispersed in water with an emulsifier. It is applied cold, then "breaks" as the water separates, leaving a bitumen film. Cationic emulsions carry a positive charge and suit most aggregates. Anionic emulsions carry a negative charge.

Storing K1-70
Temperature: Store between about 10°C and 85°C. Never let emulsion freeze, because freezing breaks it irreversibly. Never heat it above 85°C.
Tanks: Use clean vertical tanks with gentle circulation or periodic stirring. Never mix cationic and anionic emulsions, because they break on contact.
Handling: Pump with low-shear pumps and avoid air entrainment. Excessive shear or agitation can cause premature breaking.
Shelf life: Use within the period stated on the data sheet, typically weeks to a few months. Stir or circulate before use if it has been standing.
