[TCML] TESLA FRIENDLY GLUE/coating?

[mddeming@xxxxxxx]

Came across this stuff on-line. Whereas most adhesives and plastics get cloudy with UV exposure, this stuff requires UV to dry clear. Also good for encapsulating stuff and won't yellow from UV exposure.


I don't know costs yet, but I suspect it would be excellent for well-funded coils where reliability trumps economy.

Product Description
Master Bond UV24TKLO is a one part UV curable
epoxy modified formulation for bonding, sealing and
encapsulation. It passes the rigorous requirements for
low outgassing as per ASTM E-595. Most noteworthy, it
has outstanding resistance to chemicals, as described in
part below. UV24TKLO has excellent clarity and optical
transmission properties. The best wavelengths for curing
are 320-365 nm and the energy requirement is 10-40
milliwatts per cm2. This epoxy system is not oxygen
inhibited.
UV24TKLO has superb physical strength and electrical
insulation properties. The service temperature range is
-60°F to 300°F. The UV24TKLO can be cured in thicker
sections, up to 1/16 of an inch and can be easily “layered” to
higher levels. The low outgassing properties enable this UV
to be used in a wide array of optical, electro-optical
and vacuum applications that until now have not been
possible for UV curable systems. It should be noted that to
optimize the outgassing properties, the UV24TKLO should
be preheated to approximately 50°C for 15 minutes prior to
use and then allowed to cool down to room temperature.
