TS/27 industry - “thermal” lubricant polymerizable with high performances
Antioxidant of metal surfaces “FOR LIFETIME”
Steel, Brass, Copper, Zinc, Tin, Aluminium, Bronze, silver
The TS/27 industry is a LUBRICATING thermostable polymer whith a character of surface wetting agent by means of transcrystalline and intercrystalline penetration of metal surfaces into its microretassures and grains (see diagram hereinafter)
The basic molecule of TS/27 is the result of research of a group specialized in materials of very high purity intended for the monocristallography.
This thermostable resin, coded TS/27, was created by the engineers of the group, specifically to meet a need for crystalline penetration of metals, with a high thermal resistance in a very tough environment and a permittivity (or dielectric constant) targeted. Absolute permittivity of TS/27: 18,6pF/m (picofarad/meter).
But its full applications develops in electric maintenance, being protection of metal surfaces “FOR LIFETIME”, like oils of any type arising from petrochemistry or old-fashioned technical compounds on oxydable metals, in order to maintain them “conductive” whilst effectively protecting from ambient oxidation, in particular outdoors.
The TS/27 industry migrates into the crystalline microstructure of the metal surface, conferring to it an excellent resistance, even aggressive (acid or basic), like marine environment. Furthermore, for specific applications, such as switches subject to electric arcs, its thermal behaviour is exceptional (0°C + 700°C, and 1100°C at a peak) by polymerization.
A bit of metallurgy for enthousiasts: The surface absorption of the TS/27, in nanometric thickness, is explained by the mechanism of growth of the pores of the metal constituting the part “to be treated”, which utilizes physicochemical phenomena such as balance between hydrogen dissolved in the melting bath of the metal (at the time of building the part or the basic metal block) and a gazeous stage, as well as the interdentritic flow (development of arms in the cells in superfusion) of the melted metal. The source of hydrogen is mostly water, in form of vapor or hydroxide, as well as the organic material deposited on the surface of the foundry loads.
This new thermostable organic molecule, without metals and halogens, adheres to the approach of durable development by means of innovating technologies respecting environment and public health.
The TS/27 industry is not toxic and autoextinguishing. At ambient temperature, it has four essential functions :
- Releasing agent
- Anticorrosive agent
- Humidity repellent.
The TS/27 industry has no ageing effect known to date. Of great stability, it can be stored in the very long term.
Its neutral pH ensures to it excellent “chemical relations” with any kind of metals.
ALL SWITCHES PRESENT IN the CAR (subject to external ambient oxidation).
Maintenance of the switches of the fluo tubes supports in public and/or industrial places (companies, stations, airports, tunnels, street lighting…).
The oxidation of the support’s switch ends of the fluo tubes is known like a reason of premature ageing of lighting equipment.
Indeed, the fluo tubes, just to mention it, do support a few thousands of lightings.
When the switches between the support and the tube are defective by oxidation, the electric power has difficulties to flow fromt the first one to the second in order to insure a constant lighting without oscillations of the source of light.
To be clear, the rate per minute of of the fluo tube lightings, at the time of the above mentioned oscillations, is very high, and the lifespan of it is extremely reduced in time, thus also high frequency of changes.
The application in “thin layer” of TS/27 onto the above mentioned switches remowes the oxidation from metals by penetration in their crystalline structure, as mentioned above.
The permittivity of the TS/27, by means of the nanometric layer deposited on the surface of the switch, allows the easy flow of electrical power, avoiding first of all the surface graphitization due to the electric arcs, which is often and insidiously the reason of breaking the flow of electric power.
The result of this is of course, a similar application to the switches of bulb sockets (street or domestic lighting), to clamping of cables and other significant points of “escapes of power”.

The easiest way to apply TS/27 onto a metal, “to patinize” and to protect from oxidation is still the traditional brush. The dropping tube of the bottle of 125 ml makes it possible to deposit one or more drops (or a trickle) of TS/27 on the part to be treated, said TS/27 can then be extended with a paintbrush on the surface of metal.
Let penetrate the TS/27 in the crystalline micro structure at least for 3 hours. Nevertheless, one or more days will not harm, to the contrary.
Then, wipe propperly the treated metal. The surface of the part is henceforth protected from oxidation.

Experimental procedure for test of TS/27 on metals
The concerned metals, for information only, are standard steel (called carbon steel) and aluminium. In order to make it simpler, we consider that these are checking tests about the resistance to saline mist of a coating on metals.
For information purposes, the saline mist is particularly used in order to allow the evaluation of the uniformity of the thickness and the degree of porosity of metallic protection coating, considering particularly the resistance to humidity in an aggressive atmosphere.
There are several tests in saline mist :
- the standard continuous mist (ISO standards 9227, 7253, 3768, 3769, 3770, the specific standards of the car manufacturer Renault, D17, 1058, ASTM B117, B278, B368, DIN 40 046, ...),
- the saline mist spraying (see the above standards and also ASTM D2247, DIN 50 017-KK, ...),
- the saline mist in saturated atmosphere (ASTM B117, G85, ...).
Concerning the processing of metallic parts without any particular technical standards or precise application of TS/27, the experimental procedure, without any previous laboratory results, can be summarized to the identical methodology used for the “stuffing” of self-lubricating bearings, i.e. :
- by vacuum immersion in a bath of TS/27 at a temperature of 250°C to 300°C.
The duration of the vacuum immersion, in the absence of any data about the application of the treated part, will be arbitrarily defined as per 3 hours.
The treated part has to drain for 24 hours; then the required tests can be performed.
For information purposes, the technical part which has to be used in a very aggressive medium has to be treated as follows :
the part has to be placed in a heated space, saturated with TS/27 vapours, in a temperature of at least 150°C;
the space has to contain in its lower part a bath of thermostated TS/27, at a temperature which will be function of the thickness of the required film coating the metallic part to be treated;
above the thermostated TS/27 bath, the metallic part to be treated has to be progressively heated by induction, or by electrothermics, up to 450°C in about 5 hours.
Then let the part cool down to ambient temperature (in at least 8 hours); the part can be used at this stage for the applications in a very aggressive medium.
