WATER SOLUBLE BARRIER FILM CONFORMAL COATING COMPOSITION

摘要

An alkaline composition having a pH ranging from about 8.5 to about 10 comprising a first substantially hydrophilic nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 12 to about 15; a second substantially hydrophilic nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 16 to 20; a bio-film permeation agent; and an aqueous solvent, wherein a total amount of the first substantially hydrophilic nonionic alkoxylated alcohol surfactant and the second substantially hydrophilic nonionic alkoxylated alcohol surfactant in the alkaline composition ranges from about 2 to about 20 percent by weight of a total weight of the alkaline composition.
