WQ-AE-08S Anionic Asphalt Emulsion
Product Introduction
Asphalt emulsion is liquid asphalt cement emulsified in water. It is composed of asphalt, water and an emulsifying agent. The emulsifying agent is sometimes called the surfactant, which is composed of large molecules. These soap molecules are like tadpoles, having a hydrocarbon tail soluble in liquid asphalt and an electrically charged or ionic head soluble in water. The asphalt particles are surrounded by the ionic charge, which causes the droplets to repel each other and stay suspended in the water. All asphalt emulsions are designed to eventually break, or revert to asphalt and water. Some emulsions break by chemically destabilizing the surfactant, others by a simple evaporation of the water. Still others break by a combination of chemical destabilization and evaporation.
WQ-AE-08S is a relatively stable oil-in-water system formed by mixing oily solid or liquid asphalt and water through a certain process technology. In engineering applications, it is a multi-purpose bonding material with environmental protection, energy saving, and multi-functional characteristics.

Performance
- Small particle size, high gloss, excellent water resistance,
- Good stability, stable storage in a wide pH range,
- Good compatibility, high mechanical stability.
- Adaptable: The physical properties of emulsions can be modified to optimize storage, curing, mixing, traffic return and bonding strength. Emulsions readily accept additives such as polymers, latex, fillers, anti-strips, stabilizers and other modifiers to enhance the physical properties of both the emulsion and the cured asphalt.
- Flexible: An emulsion’s charge can be positive, negative or neutral to improve compatibility with available aggregates. Emulsions can be engineered for a wide variety of conditions, such as cooler temperatures or wet or dusty conditions.
Application
It is widely used in building waterproofing and industrial anti-corrosion.
Packaging and Storage Condition
Packed in 200Kg, IBC or bulk water. It needs to be sealed and stored in a cool place. The shelf life is 6 months.
