Chemguard ULTRAGUARD C135 1%-3% alcohol-resistant aqueous film-forming foam (AR-AFFF) concentrate is characterized by a substantially lower viscosity than other 1%-3% polar solvent AR-AFFF concentrates. (See Typical Properties.) Formulated using a new and proprietary technology, ULTRAGUARD C135 can improve performance in all types of foam proportioning equipment, including in-line eductors, balanced-pressure systems, and built-in systems on Fire Apparatus. ULTRAGUARD C135 also offers better fire-fighting properties than other AR-AFFF foam concentrates and is effective with blended gasoline additives, such as Methyl Tertiary Butyl Ether (MTBE) and Ethanol. ULTRAGUARD C135 is ideally suited for municipal applications, where a variety of flammable liquid spills and/or fires may occur.
Formulated from special fluorochemical and hydrocarbon surfactants, high-molecular-weight polymers, and solvents, ULTRAGUARD C135 is specified for use as a 1% proportioned solution on hydrocarbon fuels and a 3% proportioned solution on polar fuels, using fresh, salt, or hard water. When applied on a conventional Class B hydrocarbon fuel fire (gasoline, diesel, etc.) or a Class B polar solvent fuel fire (water-miscible fuels – methyl alcohol, acetone, etc.), three fire-fighting processes result:
- A film forms to help block the release of fuel vapor – an aqueous film for hydrocarbon fuels, a polymeric membrane for polar solvent fuels.
- A foam blanket forms to prevent oxygen from reaching the fire and to promote the film/membrane as liquid drains from the foam.
- Water contained in the foam cools the fire.
ULTRAGUARD C135 can be transported and stored as a concentrate, offering both ease of use and the substantial savings from reduced weight and volume.
Readily biodegradable, ULTRAGUARD C135 contains no perfluorooctane sulfonate (PFOS) or perfluorooctanoic acid (PFOA) ingredients.
