Industrial Chemicals
Due to its high viscosity, bitumen can rarely be used in its raw form. Several techniques exist to decrease the viscosity and provide a workable product, these include:
- Heating
- Huge energy consumption
- Energy consumption can be reduced by additives
- Emulsification
- Ionic emulsifiers allow dilution with water
- Adding solvents (cutback)
- Solvents tend to be petrochemical derived
- VOC containing and damaging to the environment
- Non-renewable

We offer a range of surfactants that are suitable for creating bitumen emulsions, which have applications in both road surfacing and coatings & paints industries. Using ionic surfactants is the best known technology to fully disperse bitumen in an emulsion, which is not only essential for activity and achieving an even coating of bitumen on the surface, but it also gives emulsified bitumen several advantages over the cutback and heated forms:
- Lower viscosities
- Improved surface adhesion properties
- Reduced VOC emissions
- Reduced energy costs
- Processing aids
- To reduce refining and storage temperatures
- Acidity improvers
- To adjust acid values to improve bitumen emulsion formation
