Anionic Bitumen Emulsion SS-1h is a slow-setting anionic asphalt emulsion specifically designed for applications requiring extended workability, deep penetration, and controlled breaking behavior. This emulsion is water-based and consists of finely dispersed bitumen droplets carrying a negative electrical charge, stabilized by an anionic emulsifying system.

SS-1h is widely used in cold application waterproofing, building protection, pavement preservation, and cold mix operations, where safety, environmental compatibility, and ease of application are critical.

Definition and Material Characteristics

Anionic Bitumen Emulsion SS-1h is produced by dispersing hot bitumen into microscopic droplets within an aqueous phase using a high-shear colloid mill. The emulsion is stabilized with alkaline emulsifiers—typically ammonium salts or similar anionic agents—that impart a negative charge to each bitumen particle.

In this emulsion system:

• Water is the continuous phase

• Bitumen droplets are the discontinuous phase

• Anionic emulsifier provides electrostatic repulsion and stability

The particle size typically ranges from 0.1 to 5 microns, ensuring uniform dispersion and long storage stability. Without emulsifiers, bitumen and water would rapidly separate; the emulsifier prevents this by surrounding each bitumen droplet with a charged film.

The breaking mechanism of anionic emulsions such as SS-1h occurs mainly through evaporation of water, making the breaking rate sensitive to temperature and humidity.

Performance Characteristics

Anionic Bitumen Emulsion SS-1h is characterized by:

• Slow-setting behavior for extended working time

• Excellent storage stability

• Low viscosity for easy application and penetration

• Environmentally friendly formulation (no solvents or kerosene)

• High flash point and zero fire risk during application

• Safe cold application without heating

Because of its slow breaking nature, SS-1h is ideal for applications involving fine aggregates, sand mixes, and surface coatings.

Applications of Anionic Bitumen Emulsion SS-1h

Anionic Bitumen Emulsion SS-1h is commonly used in:

• Waterproofing of concrete and metal surfaces

• Building and foundation protection

• Cold mix asphalt with fine aggregates

• Prime coats and penetration applications

• Dust control and soil stabilization

• Protective coatings for civil and industrial structures

SS-1h is especially suitable for non-fibered cold-applied waterproofing systems and can be applied using:

• Brush

• Roller

• Squeegee

• Airless spray equipment

Its slow-setting nature allows uniform film formation before breaking and full water evaporation.

Advantages of Using Anionic Bitumen Emulsion SS-1h

• No flammable solvents or petroleum diluents

• Zero fire hazard during storage and application

• Cold application with no heating required

• Environmentally friendly and low emission

• Easy handling and user-safe

• Good penetration into porous substrates

• Suitable for all climates with controlled curing

• Excellent performance in building waterproofing

Packing and Supply

Anionic Bitumen Emulsion SS-1h is supplied in:

• New thick steel drums placed on pallets to prevent leakage

• Bulk supply via bitutainers and tanker trucks

Packaging options are suitable for both small-scale construction works and large infrastructure projects.
