-50ml Dropper Bottle of Stabilant 22S (20% Stabilant 22 / 80% isopropyl Alcohol)
 
Stabilant 22 is an initially non-conductive block polymer which when used in a thin film between metal contacts becomes conductive under the effect of an electrical field. This occurs at an electric field gradient such that the material will remain non-conductive between adjacent contacts in a multiple pin environment. In addition, Stabilant 22 exhibits surfactant action, as well as lubrication ability providing a single component resident solution to virtually all contact problems.
When applied to electromechanical contacts, Stabilant 22 can provide the connection reliability of a soldered joint without bonding the contact surfaces.
 
Stabilant 22 can be used in all types of connectors, at frequencies from to DC to several gigahertz, on fader's or potentiometer's, or in non-inductive (non-arcing) power-interrupt switches. The number of uses are almost limitless.
 
Stabilant 22 is not Contact Cleaner.  it is a resident potentially electrically active material which through a synergistic combination of effects enhances conductivity within a contact without causing leakage between adjacent contacts. Thus large quantities of the material do not have to be "hosed" on, as is the case with cleaners.
 
Stabilant 22 can be quickly applied to all contacts and connectors in a system, the often difficult diagnostic determination as to which one of many contacts are erratic, can often be eliminated. This can significantly reduce service time in the field and in many cases eliminates the need to return boards for shop service or re-manufacturing. As any service manager knows, the diagnosis of electronic problems, especially where intermittent failures are concerned, is often much more difficult than the actual part replacement; as well as requiring service personnel of exceptional calibre. In many cases the use of Stabilants can thus increase the efficiency of existing staff as well as allowing many connector harness related problems to be handled at a much lower cost. 
 
Contact failure is rarely caused by a single factor. Thus, treatments that solve only one problem don't necessarily offer a reliable long term solution. For example, cleaners do not prevent the re-entry of contaminants or the reformation of contaminant films; nor do they offer any lubrication. They must be used each time a connector gets dirty. Lubricants in themselves are rarely cleaners. Corrosion inhibitors are neither cleaners nor lubricants and are often specific to one type of metal or plating. Unsaturated oils used as contact treatments can cross-link under the influence of elastomer or thermoset plastic curing agents and accelerants. 
While resident in the connector, Stabilant 22 performs several concurrent functions. Its very presence in the contact gap will prevent the entry of outside contaminants. It has sufficient surfactant action to lift surface contaminants and hold them in suspension. In cases where corrosion products are present, Stabilant 22 will penetrate them and prevent rectification effects. Due to its high dielectric constant it will act to form a capacitive layer which is in parallel with whatever residual resistance exists in the contact increasing the passage of AC signals. Given sufficient DC bias within the gaps of the contact the thin film of Stabilant will "switch", conducting by quantum tunnelling, and thus limit the resistance of the contact to a serviceable level.
 
This product is available in several forms.
  • As a concentrate (Stabilant 22)
  • As an isopropyl alcohol-diluted form (Stabilant 22A)
  • And as an ethyl alcohol diluted form (Stabilant 22E).
 
Concentrated Stabilant 22 is most useful where the connections are out in the open - such as card-edge connectors or where the lubricating properties of the material are useful -such as an aid to installing microprocessor IC's or on switches.
Where the connections are not too easy to get at or where the user wishes to apply the material to something such as a socketed IC (without removing the IC from its socket), it is easier to use the alcohol diluted form (Stabilant 22A or Stabilant 22E). The alcohol diluent serves ONLY to carry the concentrate into the connector.
 
Common Questions:
 
Just how much should be used?
Normally, a final film thickness of from 0.5 to 2 mils of the concentrate is all that it necessary. In other words, you want just enough to fill up the interstices between the contact's faces. When using Stabilant 22A, or Stabilant 22E, use enough so that once the isopropyl alcohol (or ethyl alcohol), evaporates the desired 0.5 to 2 mil film of Stabilant 22 remains. 
In applications to moving surfaces, such as in slip-rings or potentiometers, film thickness should be minimized to the point where "hydroplaning" won't occur.
 
 
How can I be sure that Stabilant works?
The best way to find out just how well it works is to try it out; that's why we have samples available. Almost every service shop or manufacturer has equipment available where the switches or connectors have become erratic over the years. Use Stabilant 22/22A/22E on them and satisfy yourself. A word of caution. Don't try to evaluate Stabilant 22's performance on brand new connectors. Instead, use it on connectors that are corroded, or dirty or just plain unreliable. We are sure that any organization dealing with electronics will have at least one piece of unreliable equipment on which the Stabilants can be tested!
 
What is the effect of Stabilant in audio equipment?
Generally it makes an audible reduction in the 'grain" of the sound, where a lot of connections are involved such as in a recording studio, the sound is usually much more open and clean sounding, with a noticeable improvement in signal to noise ratio. The material is especially effective on Schadow and similar switches, as well as on plastic element or wirewound faders. We have been told of many cases where older consoles have been improved to the point where they are back on line, and even some where they sounded better than their replacements!
 
What is the effect of Stabilant in video and CATV equipment?
In video applications, the pedestal level is usually improved; often there is a noticeable improvement in detail indicating that the signal's rise time is also shortened. In CATV applications the use of Stabilants can cut customer complaints, speed field service, and reduce RF leakage from connectors.
 
What is the effect of Stabilant when used in computers?
The effect of the Stabilants in computers, is to reduce the number of times the system locks-up or crashes, Sometimes it even eliminates non software crashes completely. The material can be used on card-edge connectors, socketed IC's and in the peripheral connectors such as IEE-488A, RS-232C, & Parallel ports. Its use in LANs can often mean major reductions in service costs as well as cutting retransmissions due to parity errors.
 
What is the effect of Stabilant 22 when used in test gear?
When used on socketed IC's, photo-couplers/isolators, rotary, push button, or slide switches, or even on BNC connectors, the net effect is usually to make the proper operation of the equipment less erratic, and in the case of IEEE-488A bus-controlled equipment, to cut down on the potential for system lock-ups.
 
Can Stabilant be used on robotic equipment?
Yes, not only can it be used on the circuit cards, but often older robotic equipment suffers from erratic contacts in the connections between the electronics section and the actuator part of the equipment even though most of these connectors are of the environmentally sealed type. Shielding case covers are often used to prevent electrical interference from welding equipment and the like. Stabilant 22 is frequently used to ensure that the covers make electrical contact with the case.
 
What about Stabilant in avionics navigation equipment and similar applications?
Stabilants have been used in the maintenance of ILS, DME, VORTAC, Loran C, both conventional and digital radar systems in both mobile (seaborne & airborne) or fixed facility operations in addition to use on HF, VHF, and UHF communications equipment.
 
Has Stabilant been used in mobile communications or paging?
Yes, not only is it being used by a number of police forces in servicing their communications equipment, it is being used by the industry as well.
 
Is Stabilant hazardous to use?
Stabilants have very low oral toxicity. Under normal workplace conditions no skin sensitization effects have been noted. In the undiluted form, it is non-flammable although if heated above 200° Celsius the decomposition products would burn. And Stabilants are environmentally friendly materials.
 
Can Stabilant be used by untrained personnel?
Thousands of applications of the consumer version of Stabilant 22 have been made over a period of several years now without any reported problems.
 
What is the best way to apply Stabilant to a contact?
The 15 ml (and the 50 ml) container have "controlled-dropper" type caps that allows Stabilant 22A to be applied directly to such components as socketed IC's, switches, connectors, etc. Some end users prefer to use industrial syrettes to apply the material. Camel's hair brushes can be used to brush it on card-edge connectors or they could be dipped into the dilute material. Most metering type liquid dispensing systems can be used as well.
 
Does the action of Stabilant deteriorate with age?
In some field trial applications lasting over fifteen years Stabilant 22 has shown no sign of reduced effectiveness. With a high molecular weight and a very low vapor pressure, little is lost by evaporation. Unlike some other contact protection oils, Stabilant 22 will not cross-link when exposed to free machining materials such as high sulfur brass, or when used on contacts where agents used to promote cross linking of thermosets or elastomers are present in the environment or in the actual connector components. Unlike non-saturated oils, Stabilant 22 does not "varnish".
