| RESISTANCE TO SOLVENTS |
|
| Resistant
to all solvents, hydraulic fluids, anti-freezes, motor oils,
petrochemical products, brine, water, steam, etc. |
| RESISTANCE TO ACIDS |
|
| Acids make
it insoluble. Only hydrofluoric acid affects it. |
| DUCTILITY |
|
| The
support may be processed following the impregnation treatment,
with no problems related to the seal of the support
itself. |
| THERMAL EXPANSION |
|
| 2.76 x 10
(to the -4th power)/per degree centigrade. Even if the
impregnating material has a different expansion coefficient
than the impregnated material, the two materials will not
separate, thanks to the high level of elasticity of the
impregnating material, which always remains well anchored to
the walls of the support. |
| THERMAL CONDUCTIVITY |
|
After it
has hardened, the impregnating material has a low thermal
conductivity by itself. Everything changes if it is in contact
with a different support. In the specific case of a support
that has a high level of thermal conductivity, the behaviour
of the impregnating material must be taken into account from
two different points of view:
1. Porosity:
Having a support with a high level of thermal conductivity,
this remains unaltered, thanks to the high contact surface
between the support and the impregnating material: a thermal
balance is reached at every point in a very short
time.
2. Surface: The quantity of heat
transmitted between the two surfaces is given by the formula
Q=K x S x AT/s = where K = the thermal conductivity, S= the
extension of the surface, AT = the temperature difference
between the two surfaces, s = the thickness of the surface.
Since in our instance s is practically equal to 0, we shall
have: Q = K x S x AT/0, but mathematically AT/0 = - therefore
Q = - this means that the infinitesimally small film that
there could be on the support does not alter its thermal
conductivity.

| DISINTEGRATION |
|
| Disintegration within the porosity does not occur. On
flat surfaces, it may happen only if it is completely dried,
in the total absence of water, at a temperature near 100
degrees (for two hours). |
