This silicone textile-coating solution raises the bar for fire safety

A1/A2 is promising, but what s/d rating does it carry under EN 13501‑1, and how does it hold up after a year of UV, dust, and light oil contamination? We use silicone‑coated fiberglass for expansion joints and blankets, and once they pick up hydrocarbon mist their fire performance drops fast - any repellency or cleanability data?
