PHOS-CHeK MVP-F Fire Retardant
PHOS-CHeK MVP-F long-term retardant is qualified by the USDA Forest Service under specification 5100-304c for use in fixed wing air tankers and helicopters with buckets. MVP-F is an all-phosphate, gum thickened, fugitive colored retardant. It is a highly effective long term retardant with a higher yield than any other retardant on the market.
PHOS-CHeK long-term fire retardants are used for wildland fire control in forest, brush or grassland. Functionally, PHOS-CHeK retardants react with and alter the decomposition of wildland fuels, so that at the qualified mix ratio they do not support flaming or glowing combustion. This deprives the fire of fuel, reducing fire intensity and rate of spread. Long-term retardants are useful in prescribed burning. When applied at low application rates, fire intensity can be dramatically decreased while slow burning continues.
PHOS-CHeK MVP-F is a highly soluble powder that mixes readily with water by recirculation, agitation or PHOS-CHeK eductor-mixer systems. MVP-F is a true fugitive color retardant that maintains visibility during application but fades to an earth tone color after exposure to sunlight.
PHOS-CHeK MVP-F is gum-thickened to medium viscosity to provide highly effective and accurate aerial drops from all air tankers. The elastic nature PHOS-CHeK MVP-F improves aerial delivery performance by reducing drift, dispersion, and evaporation and facilitates increased fuel coverage, wrap around and penetration through canopy and ladder fuels to ground vegetation. Recovery can exceed 90%. It is ideal for the use in multi-engine air tankers, VLATs, and SEATs and can be accurately dropped higher drop heights.
