Features Of Sanyo Chemical DOUBLE COAT S Waterproofing Surfactant

  1. Enhances water repellency and surface hydrophobicity in cementitious and polymer-based coatings.

  2. Improves compatibility and dispersion stability of hydrophobic agents in aqueous systems.

  3. Enables dual-layer waterproofing performance—reducing water absorption while maintaining substrate breathability.

  4. Non-ionic, low-foaming formulation ensures compatibility with common admixtures and avoids air entrainment issues.

  5. Designed for ambient-cure applications with excellent film-forming capability at low dosage levels (0.3–1.0 wt%).

Typical Applications Of Sanyo Chemical DOUBLE COAT S Waterproofing Surfactant

  1. Waterproofing mortars and tile adhesives for interior/exterior construction.

  2. Hydrophobic additives in dry-mix renderings and facade plasters.

  3. Functional component in breathable waterproof membranes for roofing and balconies.

  4. Performance enhancer in grouts and joint fillers exposed to moisture cycling.

  5. Key ingredient in pre-blended waterproofing slurries for concrete repair systems.
