EMULSITONE GLASS FORMING SOLUTION #122
Emulsitone Glass Forming Solution #122 forms a glassy inorganic film consisting
primarily of SiO2 with various modifiers to permit the films to harden at low
temperatures. The glass film which is formed will adhere to nearly all metallic surfaces
including aluminum, gold, stainless steel, copper, nickel, chromium, etc. The glass film
will adhere to all glasses and to many polymer surfaces. Glass Forming Solution #122 may
be applied to these surfaces by spinning, spraying, painting, or dipping. Where
exceptional uniformity in film thickness is required, spinning will yield best results,
with variations in thickness of less than a few percent. Glass Forming Solution #122 forms
thin films up to 10,000 angstroms on one application depending upon the nature of the
substrate. Films of greater thickness may be prepared by applying additional layers with
intermediate heat treatment between applications. The specific substrate will determine
the heat treatment required to densify the film sufficiently to permit application of a
second layer without experiencing film cracking.
Films of Emulsitone Glass Forming Solution #122 must be heat treated to achieve very hard
scratch resistant films. Reference to Table I shows the effect of heat treatment on
hardening the film. To obtain the data, a stainless steel needle of approximately a 10 mil
radius under the loading shown was used to scratch the film.
HARDNESS OF EMULSITONE GLASS FORMING SOLUTION #122 AS A FUNCTION OF HEAT TREATMENT
| Heat Treatment | Time | Weight Load On St. Steel Needle |
| Room Temperature | 16 Hrs. | 25 gms. |
| 100oC | 1 Hr. | 70 gms. |
| 200oC | 1 Hr. | 120 gms. |
| 400oC | 1 Hr. | 500 gms. |
Films of EMULSITONE GLASS FORMING SOLUTION #122 are not soluble in most mineral acids such
as aqua regia, sulfuric acid, etc. In addition, after suitable densification, these films
are only very slowly dissolved in 10% sodium hydroxide solution. Table II shows the
dissolution rates of films of Glass Forming Solution #122 in HF and 10% sodium hydroxide
solutions.

Films of Emulsitone Glass Forming Solution #122 are transparent with an index of
refraction of approximately 1.52. Films 2000 Angstroms thick show no significant
absorption in the UV or visible spectral range. The films exhibit high electrical
resistivities characteristic of glasses in general.
