Core Technology
Silway 718's potassium propyl siliconate molecules (<100 nm) penetrate substrates chemically bonding with silicates, forming an invisible hydrophobic network. With 95% vapor permeability, it reduces water absorption by 90%, preventing freeze-thaw damage and efflorescence.
Environmental Commitment
As a VOC-free, water-based solution, Silway 718 meets EU REACH and LEED standards. Its carbon footprint is 63% lower than epoxy systems, requiring only water dilution without toxic emissions.
Case Study
At France's Saint-Pierre Cathedral, Silway 718 (1:15 dilution) applied on laser-cleaned limestone reduced water absorption to 1.8% with zero efflorescence, preserving 15th-century carvings.
Critical Precautions
Avoid use on glass/metal (causes deposits). During Prague's Charles Bridge restoration, pH-neutral tapes protected lead seals, with immediate post-application rinsing.
Silway 718 is a manifesto for sustainability, enabling structures to endure time and climate with grace.
