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.
