Penetrating and Reacting for Long-Lasting Waterproofing

In construction, Methyl Hydrogen Silicone Fluid is used to impart deep, reactive hydrophobicity to porous substrates like concrete, sandstone, and masonry. Applied as a dilute solution, the low-viscosity fluid penetrates several millimeters into the pore structure. There, it reacts with atmospheric moisture and surface silanols to form a persistent, non-polar silicone resin within the capillaries.

This internal hydrophobic network drastically reduces water absorption by up to 90%, protecting the structure from freeze-thaw damage, salt crystallization, and biological growth. Unlike film-forming sealers, this treatment preserves the substrate's vapor permeability, allowing trapped moisture to escape and preventing spalling. This "breathable" protection is essential for the long-term preservation of historical monuments and modern infrastructure alike.
