Stabilant 22 has an LD50 of about 5 grams per kilogram body weight. The materials have been extensively tested for compatibility with circuit-board materials, conformal coatings, as well as with the various plastics and elastomer encountered in electronics. That's not to say that there is no chance that somewhere, someone may be able to devise a cheap plastic material that might show susceptibility to degradation from the Stabliants, but because of all the solvent-compatibility requirements that are in place in the industry, it is doubtful if this would ever be used in any commercial quality electronic equipment. 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.
Stabilants have been in some 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 loss by evaporation. World-wide patents pending.

In the event of a conflict between the instructions supplied by the manufacturer of the equipment on which the Stabilant material was used, and the service procedure employed by our customer, we recommend that the manufacturer be contacted to make sure that warranties will not be voided by the procedures.
