Hydrophobic silane-siloxane hybrid formulation for durable water repellency without surface darkening.
Reacts chemically with mineral substrates (e.g., concrete, brick, natural stone) to form covalent Si–O–Si bonds.
Low-VOC, solvent-based system compliant with major European and North American environmental regulations.
Preserves substrate breathability (vapor permeability) while repelling liquid water.
Stable in acidic and neutral aqueous environments; compatible with common cementitious admixtures.
Protective impregnation of exposed concrete façades and architectural precast elements.
Water-repellent treatment for historic masonry and restoration of natural stone cladding.
Surface protection of fired clay bricks and terracotta roofing tiles.
Moisture barrier in render systems and thin-layer plaster applications.
Pre-treatment for tile adhesives and grouts to enhance bond durability on porous substrates.
