Emulsion Bitumen – Cationic Bitumen for Africa

Slow Setting – Medium Setting – Rapid Setting – Tack Coat

Chemical surface-active agents which are serve as Emulsifiers, classified by the electrochemical charge that attained when they dissociate in a water solution. The chemical charge of Cationic Emulsions is Positive. The chemical type and quantity of surface-active agent used in the manufacturing process.

There are three major classifications of Emulsion Grades: Slow Setting, Medium Setting and Rapid Setting. The terms Rapid, Medium and Slow relate to the amount of time it takes for the Emulsion to cure. The amount of mixing that can be performed before the emulsion breaks. Emulsions that allow the longest mixing time generally take the longest to cure. Emulsions that allow very little mixing time probably set and cure most rapidly.
