TEGO® Addibit FS 725 A is a bitumen additive based on organo modified siloxanes.
Typical Applications
TEGO® Addibit FS 725 A is used as a foam stabilizer in the production of foamed bitumen.
Benefits at a glance
- Increased initial foam height
- Higher initial foam volume
- Longer half-life time leads to strongly improved foam stability (much higher foam index)
- No impact on specification of the bitumen
- No impact on the adhesion properties of the bitumen
- Temperature stable up to 170 °C for several days.
As a result, even bitumen grades with poor foaming characteristics may be used for this application.
