Anionic Bitumen Emulsion RS-2 is a specialized emulsion with distinct properties suitable for various applications. These emulsions are classified based on their breaking characteristics, with rapid-setting emulsions intended for surface dressing, while medium or slow-setting emulsions are suitable for blending with aggregates, either in concrete-type mixers or in situ. Rapid-setting emulsions are not suitable for mixing with aggregates as they tend to solidify quickly and could potentially obstruct the mixing equipment. Generally, the choice of emulsion grade for mixtures depends on the size of the aggregate, with stone mixtures requiring medium-setting emulsions and sand mixtures necessitating slow-breaking emulsions. In the case of anionic emulsions, the breaking process primarily occurs through the evaporation of water in the emulsion’s continuous phase, making them sensitive to temperature and humidity, which can influence their breaking properties.

Anionic bitumen emulsion is characterized by its negative charge, a common attribute found in many substances. The industrial coatings industry has conducted extensive research and development to formulate coatings based on anionic systems due to their prevalence. When an anionic emulsion is mixed with a cationic emulsion, a strong bond forms, resulting in the transformation of the substance into a solid material. However, this property is not suitable for coating applications, as it cannot be effectively applied to substrates.

Application of Anionic Bitumen Emulsion RS-2: Anionic Slow-Setting Bitumen Emulsion RS-2 is a cold, non-fibered liquid waterproofing bitumen emulsion. The product is manufactured through a process involving bitumen, special emulsifiers, water, and other additives that pass through a high shear rate colloid mill. The properties of the bitumen directly affect the emulsion’s specifications. RS-2 is specifically designed for waterproofing and building applications, including use on concrete and metal surfaces. Its high flash point and low solvent content make RS-2 user-friendly and safe. RS-2 can be applied using various methods such as paint brushes, squeegees, airless sprayers, and rollers.

Anionic Bitumen Emulsion RS-2 is recommended for Surface Dressing treatment, and the application rate, as per MoRTH (Ministry of Road Transport and Highways) guidelines, is as follows:

Application	Quantity in kg/10sqm area
Two coat surface dressing	28 to 32
