Re: [ATM] Protect a finished optical surface to work on reverse

Hi Arnold,

(It is spelled collodiOn.)

In order to obtain quick drying by evaporation of solvent, ether was used
for solvent.
This is probably main reason why it is considered as hazardous.
Highly flammable ether in combination with  combustible
nitrocellulose may warrant heavy  burns if spilled and glued to skin and 
caught fire.
Although it was used for cleaning optics, I will avoid it. There are
other, les hazardous and still efficient  methods.

>There is a product made for this purpose, called "Pre-cote 33 Blue
>Spray" protective coating, part #LB0004 sold by Universal Photonic

Have you seen declaration for this product. What does it contains?

Regards
Vladimir.
