Non-sacrificial
No intumescence and no charring step. The film doesn't swell, react or consume itself to work, so it keeps protecting through weather cycles.
FIRE PROTECTION
Protection that's in place before the fire arrives.
A passive fire protection coating for exterior wood that stands in the open: poles, fences, bridge timbers and trail structures. Built with NanoTech Materials' Wildfire Shield and installed by NanoGuard.
Rejects radiant heat on contact.
Bonds to wood
Built on NanoTech's insulative ceramic particle platform and engineered for exterior wood that faces sun, rain and temperature swings year-round.
Tested to named standards
ASTM E84 surface burning (Class A, flame spread 0, smoke developed 0), ASTM E119 fire resistance, ASTM E162 radiant-panel flame spread, ASTM E662 smoke generation and ASTM G124. Rated by the manufacturer to withstand temperatures up to 3,272°F (1,800°C).
Applied without primers or topcoats. 10-year manufacturer materials warranty. After direct flame contact, the coating is inspected and recoated where the film was damaged.
Where it's used
- Utility poles
- Timber retaining and lagging walls
- Bridge and overpass timbers
- Wooden fencing
- Boardwalks and trail structures
- Park signage
