The cationic bitumen emulsion can be modified with Nanotac to be used as a chip seal emulsion which will improve bonding to the base and to the stone chips. It gives improved strength to the bitumen film. It also makes the surface dressing water proof. The setting time required by the chip seal is reduced considerably with the addition of NanoTac and it also reduces the slippage of the surface dressing. The addition of Zydex technology to the chip seal provides a better binding of the chips to the base along with a substantial increase in the bond strength.
