Post-application Discoloration/Tinting of Stabilant 22 Films

Introducing Stabilant 22

Stabilant 22 is an initially non-conductive block polymer that when used in a thin film within contacts switches to a conductive state under the effect of the electrical field. The field gradient at which this occurs is set such that the material will remain nonconductive between adjacent contacts in a multiple pin connector environment.


Thus, Stabilant 22 provides the connection reliability of a soldered joint without bonding the contacting surfaces together!


Contacts are generally the weakest link in any piece of electrical/electronic equipment whether it be in low current devices found in computers or higher current circuits found in automotive and aviation applications, to name only a few. The use of Stabilant 22 or its isopropanol-diluted form, Stabilant 22A, will make contacts from 10 to 100 times more reliable, eliminating costly service call-backs and ensuring customer satisfaction.

What causes color tinting of Stabilant after application on contacts?

Some customers have commented that when Stabilant 22 was used on some contacts, the film has acquired a pale colored tint (ranging from indigo through green) and have expressed concern over this phenomenon.


It occurs primarily because of minute amounts of corrosion being present either on the surface of the connector material, in locations where there are pinholes in the precious metal plating that is often employed, or at the nonplated and therefore unprotected edges of card edge male contacts. The application of the Stabilant lifts and dilutes these trace corrosion products producing the visible color change. Many metal oxides or corrosion complexes are often highly colored (as demonstrated by their use in artist's pigments) and a very minute amount can result in a tinting of the otherwise colorless Stabilant film. Part of Stabilant's beneficial action is its ability to keep these from interfering with the actual contact interface.


If this coloration is of concern, reapplication of the Stabilant will so dilute it as to render it negligible. However, as the color rarely has any effect on the proper operation of the connector most service personnel or manufacturers simply ignore the effect.
