Protectosil WS 700 P

For the hydrophobation of dense building materials

Protectosil WS 700 P is a paste-like impregnation based on silane chemistry for the hydrophobation of dense building materials especially alkaline substrates such as concrete.

Key Features

  • Very high reactivity and resistance against alkali
  • Shows optimum penetration even in dense mineral substrates
  • Shows no formation of sticky silicone films
  • Gives invisible and water vapor permeable protection
  • Reduces significantly the uptake of water
  • Reduces the uptake of water soluble pollutants
  • Protects hair like cracks of up to 0,3 mm
  • Applied undiluted
  • Has a long contact time with the substrate due to its paste-like consistency thus allowing for very high penetration depth, reducing loss of material by run-offs, and facilitating overhead applications

Recommended Applications

  • Suited for the hydrophobizing impregnation of porous, mineral substrates
  • Serves as a chemical dampf proofing agent (applied by injection)
