ATM A new spin on epoxy mirror problems
Greetings,
Regarding exothermic reaction of epoxy mirrors (and small volumes of
epoxy to use because of it)
how about this: Spin a water mirror in a freezing environment (preferably
controlled).
This will form the base for your epoxy mirror.
Mix your epoxy cold, in the right amounts. For superior results, bubbles
can be removed from the epoxy using a high vacuum.
Place the epoxy on the water mirror, and spin to the same speed.
The idea here, is to use the inertia of the epoxy (and water mirror) to keep
the epoxy temperature manageable. Also, to keep the reaction rate very,
very slow.
If successful, the finished epoxy mirror will be of uniform thickness,
rather like slumping a glass mirror to a mold. In this case, gravity is our
mold maker.
The epoxy, once cured (could take days or much less/more depending on the
temperature, type used and quantity), obviously won't stick to the water
base (especially after you melt it). Note: this suggestion is 100% theory,
no artificial additives, colorings, or preservatives. But, please let me
know if it works! =)
