LK-Aqua EM 290Q

Water repellent additive for cement

Introducing LK-Aqua EM 290Q: Advanced Water-Repellent Cement Additive

LK-Aqua EM 290Q is an innovative silane based additive designed to significantly enhance the durability and longevity of cement by imparting superior water-repellent properties without interfering with the hydration process.This is a next-generation solution for achieving long-lasting (durable in humid environment), high-quality cement structures with built-in water repellency. Perfect for infrastructure, residential, and industrial applications, this additive ensures superior performance without compromising the integrity of your cement formulations.

Key Features & Benefits:

  • Superior Water Repellency: Forms a hydrophobic barrier to reduce water absorption and ensures deep penetration for enhanced performance.
  • Enhanced Durability: Reduces water absorption to prevent spalling from freeze-thaw cycles and increases resistance to cracking in extreme weather conditions. Also extends the shelf life of cement bags in humid conditions.
  • Efflorescence Resistance: Prevents white salt deposits by controlling water movement within the cement.
  • Eco-Friendly & Easy to Use: Solvent-free, aqueous-based, environmentally friendly, and requires a low dosage with fast water-beading action.
  • Maintains Breathability & Aesthetic Appeal: Allows vapor transmission while repelling liquid water and preserves the original look of the cement surface.

Technical details:

Usage Instructions:

  • Dosage: To be optimized based on cement type and application requirements. For OPC cement worked well dosage ~ 0.06- 0.08%
  • Application Method: Add directly during clinker grinding for best integration.

Applications:

LK-Aqua EM 290Q is added during the clinker grinding stage to ensure uniform dispersion and long-term performance. This treated cement is suitable for:

  • Waterproof plaster & mortar
  • High-performance concrete in humid climates
  • Precast concrete for long-term durability
  • Bridge decks, tunnels, and marine structure
