Performance & Testing
- Weathering Resistance (DIN EN ISO 4892-1:2006): Coating remains effective after 550 hours of accelerated exposure, equivalent to 5 years of weathering.
- Frost-Thaw & Salt Resistance (DIN EN 12371:2010-07 / TL Pflaster-StB 06): Treated stone showed significantly reduced mass loss after 100 cycles, confirming high durability against freeze-thaw and de-icing salt conditions.
- Water Vapour Diffusion (DIN EN ISO 12572:2001): No negative impact on breathability; permeability remains intact.
- Water Absorption (CSIRO BEST-2:1998): Water absorption reduced to 3.87% by weight on sandstone surfaces.
- Salt Damage Resistance (AS/NZS 4456.10:2003): Treated surfaces exhibited high resistance to damage from salt exposure.
- Abrasion Resistance (ASTM C1353:1996): Achieved an abrasion index of 11.36, indicating improved surface strength and wear resistance.
- Hydrophobicity: Demonstrates pronounced water repellency with superhydrophobic behaviour, forming a thin, protective layer without altering vapour permeability or substrate appearance.
- Food Contact Safety: Confirmed physiologically safe for surfaces that may come in contact with food.
- Environmental Compliance:
- REACH Compliant
- ZDHC MRSL V2.0 Compliant
