Flamex PF-1 wood fire retardant penetrates the substrate and becomes part of its molecular structure. When the treated wood is subjected to an open flame, Flamex PF-1 will reduce the flame spread to a Class A or B rating depending on application coverage.
Flamex PF-1 is non-toxic and non-hazardous to the environment and simple to apply.
When Flamex PF-1 wood fire retardant is applied, the wood substrate being extinguished is cooled down by the thermal endothermic reaction, and produces extinguishing water that does not evaporate as quickly as regular water does.
The burning material can therefore be wetted more effectively, making it easier to contain the fire and avoiding the high temperatures that normally occurs with a fire. When catching fire, the treated wood is immediately cooled, and therefore will not burn and cannot be ignited easily.
Extinguishing water becomes a chemical water that contains a nitrogen and oxygen mixture and forms a gas that replaces the surrounding oxygen which a fire needs to survive.
Since Flamex PF-1 wood fire retardant penetrates and becomes part of the substrate. the life of the flame retardant is permanent as long as it is applied in a humidity controlled environment. If the environmental humidity cannot be sustained at 70% or below, we recommend using Flamex PF-2.
Flamex PF-1 wood fire retardant will not alter the structural integrity of wood. Flamex PF-1 is often chosen because it is non-toxic, dries clear, and is easy to apply with a sprayer. Once cured (12 hrs.) the treated material may be painted with a latex paint. Use only solvent based clear coats.
Flamex PF fire retardant spray has been tested to the following standards: ASTM E-84, NFPA 255, and UL 723
