For anionic emulsions, there are several grades of different breaking characteristics. Rapid-setting emulsions are used for surface dressing, while medium or slow-setting emulsions are used for ‘mixtures’, that is mixed with aggregate either in concrete-type mixers or in situ. Rapid-setting emulsions are not used for mixtures because they would tend to set during the mixing process and clog the mixer. Generally, in making mixtures, the finer the aggregate used, the slower setting the emulsion that has to be used. Therefore, stone mixtures require medium-setting emulsions and sand mixtures require a slow-breaking emulsion. With anionic emulsions, the breaking process is predominantly by evaporation of the water in the emulsion continuous phase. Because of this, anionic emulsions are susceptible to temperature and humidity in terms of their breaking properties.
An Anionic bitumen emulsion has a negative charge, most of the things in the world are Anionic and that is why the majority of Research and Development, formulating, and lab testing has been done in the Industrial Coatings Industry to make coatings from Anionic systems.
KEY FEATURES
APPLICATION PROCESS
Anionic Slow Setting Bitumen Emulsion is the cold/non-fiberated liquid applied waterproofing bitumen emulsion. The product is made using a process in which the bitumen, special emulsifier, water and other additive have been gone through a high shear rate colloid mill and the properties of bitumen have the direct effect on the emulsion specification. This product has been specifically developed to provide waterproofing and building application, concrete and metal surface. The high flash point and the low solvent content make RS-1 an easy to use and a safe product. RS-1 can be applied by using a painting brush, squeegee, airless spray, and roller.
Apply the emulsion to the clean surface with a distributor spray or brash. Application temperature should be between 20 to 70 °C. RS 1 grades of emulsions should not be diluted with water. Traffic must be controlled according to a traffic control plan and be kept off the sealed area until the emulsion breaks or until it does not adhere to vehicle tires. More details about applications methods are available upon request. Emulsions can be removed from equipment and tools with water when it is wet. When dry it can be removed by any suitable solvent such as gasoline or kerosene.
