Anionic Bitumen Emulsion QS-1h is a specialized emulsion with unique 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.

Rapid-setting emulsions are avoided for mixtures because they tend to set quickly during the mixing process and could potentially clog the mixer. The choice of emulsion grade for mixtures depends on the size of the aggregate, with stone mixtures requiring medium-setting emulsions and sand mixtures needing 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 affect their breaking properties.

Anionic bitumen emulsion has a negative charge, a common characteristic found in many substances. The industrial coatings industry has extensively researched and developed 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 QS-1h

Anionic Slow-Setting Bitumen Emulsion QS-1h 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. QS-1h is specifically designed for waterproofing and building applications, including use on concrete and metal surfaces. Its high flash point and low solvent content make QS-1h user-friendly and safe. QS-1h can be applied using various methods such as paint brushes, squeegees, airless sprayers, and rollers.
