Berolan LP 70 is an air-entraining agent and plasticizer with strong surface-active properties, specifically developed for use in cement, gypsum, or lime-based mortar systems. This product improves the rheology of mortar mixtures, providing higher yield and superior workability.

Key Properties and Advantages

  • Enhanced Workability: Improves the wetting of the mortar, facilitating ease of application.
  • Surface Quality: Extends the open time, reducing tearing and skin formation on the plaster surface.
  • Equipment Compatibility: Reduces wear in mixing units and decreases the tendency for agglomeration.
  • Shrinkage Control: Reduces shrinkage, minimizing the risk of crack formation.
  • OHS Compliance: The risk of respiratory tract irritation is minimized.
