Alkali silicate / silica sol film · YR-9805
Exterior Wall Inorganic Paint
YR-9805-(01-09)
1 / 6
YRong exterior wall inorganic paint forms a sol–gel network from alkali metal silicates and silica sol with inorganic pigments and nano fillers—built for weatherability, A1 fire performance, breathability, and scrub resistance on coastal, industrial, and heritage façades.
Versus conventional organic exterior systems, this mineral path targets about 1500 h artificial weathering without chalking, scrub ≥10,000 cycles, fire class A1, plus breathable and optional self-cleaning performance.

Product features
Inorganic sol–gel network: weatherability, fire safety, breathability, scrub resistance, with optional antibacterial / self-clean upgrades.
Key strengths
- Weathering — about 1500 h artificial aging without chalking or fade.
- Scrub ≥10,000 cycles (GB/T 9266); fire class A1 (GB 8624).
- Breathability ~0.5 g/(m²·24h); coastal salt spray can reach ≥1000 h.
- Eco profile — free formaldehyde ≤5 mg/kg (GB 18582-2020). Certificates available on inquiry.
- Substrate friendly — adhesion ≥1.2 MPa on brick/stone for heritage façades.
Applications
- Coastal buildings: salt and humidity-exposed façades
- Industrial sites: acid/alkali and abrasion-prone exteriors
- Historic façades: brick-tone restoration and color hold
- Long-cycle projects: exterior systems in the ~10–15 year service range
