Sigma Siloxan Hydrophob Aqua - Hydrophobizing Agent


Sigma Siloxan Hydrophob Aqua is a waterborne hydrophobic agent based on amino-functional siloxane compounds and fluorine components. The product is highly suitable for absorbent mineral substrates, such as brick, sand-lime brick, concrete, aerated concrete and natural stone, as well as facades finished with cement plaster.

Key features

  • Eliminates the capillary action of porous mineral building materials 
  • Makes stony building materials water-repellent on the surface, preventing rainwater from penetrating and preserving the insulation value of exterior walls 
  • By treatment, oily contaminants such as exhaust fumes from cars and emissions from heavy industry, do not reach the façade. 
  • Prevents frost damage, soiling, salt deposits, algae and mould growth
