In addition to this I compare multiple methods of intumescent fire protection to find out if expandable graphite preforms as well as carbon foam. As a result of my tests in this video: For indoor intumescent fireproofing I recommend using commercially made paints containing ammonium or melamine polyphosphate and pentaerythritol. I have not compared brand names to identify the very best fireproof paint, but several that I believe will provide very good protection are as follows: - Contego Reactive Fire Barrier - Firetect WT-102 - Fireguard E84 - Flameoff Fire Barrier Paint Robert Murray Smith's intercalated graphite playlist:    • Graphene Intercalated Compounds   Thank you to everyone that supports this channel on Patreon!
