FR-600 is our ground optimized liquid concentrate long-term retardant, specifically designed for utility right-of-way protection in high risk fire areas. This product is fully qualified with the USFS (United States Forest Service).
FR-600 features our unique magnesium chloride formulation, which means that it's more effective, safer for the environment, and more durable than conventional, fertilizer-based retardants. This formulation is specifically designed for large area applications using standard ground application equipment. FR-600 pretreatments are most effective when applied at the beginning of the wildland fire season, and will remain effective until diluted by substantial rainfall.
Approved by the USFS and listed on the Qualified Products List.
Designed for wet concentrate storage and wet base operations.
Higher salt content to better stop ignitions and fire spread, and maximize longevity. Developed for long-term pretreatment of Tier 3 hazardous wildland fuels.
Formulation optimized for pre-treatment of utility right of ways and infrastructure with exceptional durability and rain resistance.
Gum-thickened low-viscosity for penetration of dense fuels.
Provides higher visibility during the day and at night, and fades over time when exposed to sunlight.
Self-hydrating when humidity exceeds 35%, enabling better fuel coverage, more effective fire suppression, and extended durability.
Not a fertilizer, does not contribute to the growth of flammable vegetation or freshwater eutrophication, does not contain any biocides, and is significantly less toxic to fish.
Corrosion inhibitor package minimizes corrosion on steel, brass and aluminum, making it safe for use around steel utility infrastructure.
