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
- Viscosity: CMS-2 emulsion has a moderate viscosity, which allows for easy handling and application at ambient temperatures. Its viscosity can be adjusted to suit specific application requirements. The viscosity of CMS-2 emulsion is generally in the range of 30 to 150 cSt (centistokes) at 25°C (77°F). Viscosity can be adjusted to meet specific project requirements.
- Setting Time: CMS-2 emulsion typically has a relatively quick setting time, which means that it starts to break and cure relatively soon after application. This property is essential for ensuring that the emulsion bonds effectively with the substrate.
- Cohesion and Adhesion: It exhibits good cohesion, which refers to its ability to stick to itself, and adhesion, which refers to its ability to bond to other surfaces. This makes it effective for applications like tack coats and surface treatments.
- pH Level: The pH of CMS-2 emulsion is typically slightly acidic, ranging from 2.5 to 5.5. This acidity helps with stability and bonding.
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
Emulsion Bitumen CMS-2 is a hazardous material and should be handled with care. Some safety tips when using Bitumen Emulsion CMS-2 are:
- Protective Equipment: Always wear appropriate PPE when handling , including gloves, safety goggles, and protective clothing.
- Ventilation: Ensure adequate ventilation in work areas to prevent the accumulation of fumes or vapors.
- Fire Safety: Be aware of the flammable nature of bitumen and take necessary precautions to prevent fires. Keep fire extinguishing equipment on hand in work areas.
- Transfer: Ensure safe transportation of Emulsion CMS-2 by complying with transportation regulations and guidelines for hazardous materials, if applicable.
- Handling and Storage: Store Emulsion CMS-2 in designated areas away from open flames, heat sources, and incompatible materials. Follow the manufacturer’s guidelines for storage conditions.
Use proper handling techniques to minimize the risk of spills or splashes. In the event of a spill, follow established spill response procedures.
