Binder for Phospors

The use of binders such as sodium silicate, silicafilm, and silicon oil to give adhesion to phosphors used in display devices all present some difficulties or drawbacks, in one way or another.

However, it has been found that silicon resin acts to provide good adhesion for phosphors in display devices. A typical mixture of 3 grams of phosphor mixed with 10 ml ethylalcohol and 2 drops of silicon resin (SR-82) has been found to be effective. Higher concentrations of SR-82 have been found effective and do not interfere with ultraviolet excited luminescence. Lower concentrations can likewise be used effectively, but with a corresponding reduction in adhesion.

Other silicon resins may also be employed, but SR-82 is particularly well suited. Since SR-82 is commonly employed as a leak sealant in sealing flaws in ultrahigh vacuum systems, it is therefore extremely inert, and can withstand temperatures of at least 450 degrees C. In addition such a resin will not outgas significantly.
