Water soluble barrier film conformal coating composition and method of cleaning contaminated surfaces

摘要

An alkaline composition is described having a first nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 10 to about 15, a second nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 16 to 20, an aqueous solvent, and a bio-film permeation agent. A total amount of the first surfactant and the second surfactant in the composition ranges from about 2 to about 20 percent by weight of a total weight of the composition.
