DOW DOWSIL 1-6184 is a 98% active siloxane-based water repellent with ultra-low VOC (370 g/L), engineered for extreme construction environments. It appears as an amber liquid (viscosity 15 cSt) and forms true solutions when diluted to 2.5-15% concentration, penetrating over 50 mm into porous substrates. Its self-crosslinking formula creates a permanent hydrophobic barrier (contact angle >120°) within 24 hours, complying with German WTA 4/4/04-D standards for historic building restoration.
Ultra-Low VOC: Meets strict global regulations including EU BPR, aligning with low-emission construction requirements.
Self-Crosslinking: Chemically bonds to substrates, achieving a shear strength of ≥5 MPa for long-lasting adhesion.
Deep Penetration: Molecular weight <800 Da enables resistance to 10 bar water pressure, ensuring thorough substrate protection.
Broad Compatibility: Effective on limestone, concrete, and acrylic coatings, fitting diverse construction material needs.
Historic Preservation: Used for damp-proof course injection in masonry walls (5.4-7.5% concentration) to protect historic structures from moisture damage.
Concrete Protection: Reduces chloride penetration by 90% in new concrete structures, extending their service life.
Cultural Heritage: Enhances sandstone freeze-thaw resistance to 100+ cycles, safeguarding cultural heritage sites in harsh climates.
Industrial Flooring: Offers FDA-compliant acid/alkali resistance (pH 1-12), suitable for food-grade or chemical-processing industrial floors.
Tunnel Engineering: Withstands 1.2 MPa hydrostatic pressure in tunnel linings, preventing water seepage in underground infrastructure
