Stabilants have been in some field trial applications for over fifteen years now, without showing any sign of reduced effectiveness. The material has a high molecular weight and a very low vapor pressure, thus it is not prone to evaporation. The phenomena of 'varnishing' does not occur with Stabilant 22 . Some end users prefer to buy larger quantities and use industrial syrettes to apply the material onto connections. Camel's hair or sable brushes can be used to brush it on card-edge connectors.
Cards can also have their edge connectors dipped into the dilute material.
Even though some was left on the wiper used, it too evaporated. The equipment became erratic in operation four months later, and the contacts had to be re-cleaned. In the proceeding year, the same approximate pattern had been repeated to the point where we could safely say that the annual solvent usage for that set of contacts was about 60 mL. The next time that we had the equipment malfunction we used 2mL of Stabilant 22A which released 1.6 mL of isopropanol to the atmosphere. Stabilants do not contain any ODC's such as CFC'S, HCFC's or Trichloroethylenes, nor are such chemicals used in their manufacture. Neither the Stabilants themselves, nor any of the inks used on their labels or packaging, contain Lead, Cadmium or Hexavalent Chromium.
