MS

Understanding MS

Medium or slow-setting emulsions are essential for creating mixtures with aggregates, either in concrete-type mixers or on-site. Rapid-setting emulsions are unsuitable for this purpose as they may set too quickly, causing mixer clogging. Generally, finer aggregates require slower-setting emulsions: medium-setting emulsions are needed for stone mixtures, while sand mixtures benefit from slow-breaking emulsions. Anionic emulsions primarily break through evaporation of water, making them sensitive to temperature and humidity.

Applications:

  • Premix Carpet:
    Usage: 20-23 kg per 10 sqm area

  • Pothole Repair:
    Usage: 7% of the weight of the aggregate

Key Considerations :

  • Temperature and Humidity: Monitor environmental conditions to ensure optimal breaking and performance of anionic emulsions during application.
  • Mixing Technique: Ensure proper mixing techniques to achieve the desired consistency and performance for each application.
