Omega Fire is a single component coating having a blend of seven different ceramics combined in a water-based, acrylic/hybrid modified silicone formula to create a barrier against extreme flame impingement and heat migration. The coating can withstand direct flame up to 2200°F (1204°C) by hardening on the surface at first contact, while continuing to provide the necessary insulation value. The resin blend binds the compounds together and forms a char causing a matrix with the ceramics across the face of the coating, facing the flame.
Omega Fire is designed to stay intact with constant adhesion at extreme temperatures, while remaining flexible. In this way, it can move with the surface, during expansion and contraction, without cracking and falling off as the substrate moves.
