RE: Speculation........

Why wouldn't Sumiko obtain the already diluted Stabilant directly from the manufacturer? I.e., Stabilant 22A or Stabilant 22E. It's pretty obvious one should dilute Stabilant with a rapid-evaporating one such as Freon or pure alcohol.
From Applications Note,
"In what forms is Stabilant available?
The Stabilants are available in several forms. As a concentrate (Stabilant 22), an isopropyl alcohol-diluted form (Stabilant 22A), and an ethyl alcohol diluted form (Stabilant 22E). For example, a given size container of Stabilant 22A will cost about one-fifth the amount of a container of Stabilant 22 as it contains only one-fifth the amount of the concentrate. Another form of packaging is available. Stabilant 22S packages the concentrate such that it occupies one-fifth the volume of an otherwise empty container. This allows the end-user to add his own diluent, and thus saves the added costs of shipping the diluent (e.g.: isopropyl alcohol), as well as allowing the end-user to use an alternate diluent such as one of the Freon-based solvents.
In addition a 0.5 ml vial of Stabilant 22A is available for manufacturers to include with plug-in circuit boards."
