CHEMGUARD FS-125 is a highly concentrated, proprietary blend of CHEMGUARD short chain fluorosurfactants. This “superconcentrate” has been designed to be used primarily for the formulation of high efficiency PFOA-Free AFFF concentrates that meet the requirements of UL Standard (UL 162) and US Military specifications, such as Mil-F-24385F, and PFOA-Free AR-AFFF concentrates. It can be diluted directly with fresh (tap) water and appropriate amounts of hydrocarbon surfactants and solvents to manufacture AFFF’s (3 and 6%). With a proper adjustment of the dilution ratio to prepare the concentrate, one can formulate AFFF products that can meet other specifications.
