Protectosil® WS 800 P

Impregnation paste based on silane chemistry for the hydrophobation of dense building materials especially alkaline substrates such as concrete.

Scope of Application

Protectosil® WS 800 P is suited for the hydrophobizing impregnation of porous, mineral substrates shows 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 and water based pollutants is 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
