Repsol Advance - Long Life Emulsions

Emulsions are defined as a heterogenous, thermodynamically unstable system that is composed of two phases: the bitumen phase and the water phase, formed by water, emulsifiers, and pH regulators.

Properties and applications

Due to this natural instability, a process takes place over time that causes decantation of the binder phase, with the water and bitumen gradually separating. This ultimately causes the emulsion to break down in part or in full, going from a typical phenomenon of flocculation to coalescence and finally sedimentation.

To solve these problems, Repsol has developed a range of emulsions called Repsol ADVANCE and EFI-ADVANCE LONG LIFE, which have a great storage stability, improving the natural sedimentation process over time. These types of emulsions can be stored in tanks for use in small, sporadic actions, making them available in suitable handling conditions and with all the proper characteristics for use.
