2025 Aerogel High-Temp Coating – Real Factory Prices & Steel Mill Cases

We Just Launched One-Coat 800μm Aerogel Paint That Survives 1200°C – Here’s What Happened on Real Jobs

Ruibin here, InsulateWool / Hebei Woqin. For years we only sold blankets and panels, but every month a maintenance manager rang: “Your aerogel is amazing, but we can’t wrap every pipe—can you make a paint version that actually works above 600°C?”. So we did.

What we actually ship now (no lab fairy tales):

One spray coat = 600-1000 μm thick (yes, one pass)

Fresh conductivity 0.023 W/m·K @ 300°C

After 1000 cycles -196°C to 650°C: still under 0.032

Adhesion 95% after 1200°C flame test

Salt spray 5000 h: corrosion rate 0.003 mm/year

Three jobs we finished in the last 9 months:

Shandong steel mill blast furnace skirt Sprayed 0.8 mm on 550°C steel. Surface temp dropped from 180°C to 48°C. Maintenance crew cut welding repairs 58%. Already reordered 40 drums.

Guangdong LNG terminal spherical tank Coated the outer shell instead of 8-layer ceramic fiber. Inspection interval jumped from 24 months to 60 months. Zero corrosion under typhoon salt spray.

Hebei chemical plant 400°C steam line Old rock wool jacket kept falling off. One weekend spray job, surface now 42°C. Steam loss cut 68%. Payback 11 months.

2025 factory prices (drum, FOB Tianjin):

Standard grey (650°C) – USD 16-18/L

Silver high-reflectivity (1000°C+) – USD 20-22/L

Custom colour / thicker version – ask

One rule that kills 70% of bad jobs:

Don’t thin it more than 10%—viscosity drops and you get pinholes. We ship pre-thinned ready-to-spray drums and a 3-minute video so your painter doesn’t mess it up.

Want to test on your furnace or tank?

Free 5L drum worldwide—you only pay freight (USD 180-280 by DHL). Comes with spray gun settings, test report, and my WeChat for midnight panic calls.

This paint isn’t cheap, but when one coat saves you three shutdowns, nothing else comes close.

Drop your surface temperature and pipe diameter—I’ll tell you in 10 minutes exactly how many litres and what payback looks like.

We burned the samples at 1200°C so your plant doesn’t have to.
