Cationic Bitumen Emulsion CMS-2

What is Bitumen Emulsion CMS-2 ?

Bitumen Emulsion CMS-2 consists primarily of bitumen and water. The bitumen is typically a medium-grade bitumen. Emulsifiers and stabilizers are added to create a stable mixture. These additives help keep the bitumen and water from separating over time.

Bitumen CMS-2 is relatively viscous, making it suitable for a wide range of applications, including surface treatments, tack coats, and cold mix asphalt. Also, CMS-2 can be applied at ambient temperatures, making it suitable for cold weather and damp conditions. It can be easily mixed and sprayed onto the road surface, allowing for quick and efficient construction and repairs.

Emulsion CMS-2 can be used for chip sealing when using dirtier aggregate. However, because it is medium-setting, traffic control may have to be adjusted. The setting speed of any emulsion is relative to atmospheric conditions at the time of construction..

Application of Bitumen Emulsion CMS-2

Cold Mix Asphalt:

Bitumen emulsion CMS-2 can be used to create cold mix asphalt. In this application, the emulsion is mixed with aggregates (such as gravel and sand) at ambient temperatures to create a workable mixture. Cold mix asphalt is used for patching potholes, repairing small sections of roads, and performing quick, cost-effective repairs.

Construction of Low-Traffic Roads:

CMS-2 emulsion is suitable for the construction of low-traffic or rural roads, where the use of hot mix asphalt may not be cost-effective or feasible. It allows for road construction at ambient temperatures, reducing energy consumption and environmental impact.

Anti-Corrosion Coatings:

Bitumen emulsions, including CMS-2, can be used as protective coatings for industrial equipment, pipelines, tanks, and structures to prevent corrosion. The emulsion is applied to the surface, forming a durable and waterproof barrier that inhibits the contact of moisture or corrosive substances with the underlying metal.

Adhesive and Sealing Compounds:

CMS-2 can be used as an ingredient in adhesives and sealants, particularly in situations where a waterproof and durable bond is required.

Soundproofing:

Bitumen emulsions can be used as a component in soundproofing materials for industrial buildings, equipment enclosures, and sound barriers. They help dampen sound vibrations and reduce noise pollution.

Properties of CMS-2

CMS-2 bitumen emulsion is characterized by moderate viscosity, typically ranging from 30 to 150 cSt at 25°C, allowing for easy handling and application at ambient temperatures, with the flexibility to adjust viscosity based on specific project needs. It sets relatively quickly after application, ensuring effective bonding with the road surface.

The emulsion also demonstrates strong cohesion and adhesion properties, making it ideal for tack coats and surface treatments where both internal strength and surface bonding are crucial. Additionally, its slightly acidic pH level, usually between 2.5 and 5.5, contributes to emulsion stability and enhances bonding performance.

Bitumen Emulsion CMS-2 Advantage

• Cost-Effective: Using Emulsion CMS-2 can be cost-effective, particularly in scenarios where the production and application of hot bitumen would be more expensive. It requires less energy during production and application, contributing to cost savings.
• Water Resistance: It provides excellent water resistance once it cures and sets, which helps protect the underlying road structure from moisture damage.
• Enhanced Skid Resistance: When used for surface treatments, CMS-2 can improve skid resistance, increasing road safety by reducing the likelihood of accidents caused by slippery road surfaces.

Safety Tips of Bitumen Emulsion CMS-2

Personal Protection and Ventilation: Wear appropriate personal protection equipment (PPE) when dealing with CMS-2 bitumen emulsion, including gloves, goggles, and protective clothing. Operate in well-ventilated spaces to prevent the build-up of hazardous fumes or vapors that may be released during handling or application.

Fire and Storage Safety: Although CMS-2 is an emulsion, it still contains flammable components. Keep it away from open flames and heat sources, and have fire extinguishers nearby. Store the emulsion in approved containers, in dry, cool locations as per the manufacturer’s instructions, and away from incompatible materials.

Handling and Spill Response: Apply safe handling practices during application and transfer to minimize the possibility of spills or splashes. If a spill occurs, immediately take proper spill response actions. Additionally, follow all transportation regulations when moving CMS-2 since it may be classed as a hazardous material.
