Re: ATM Gluing Lexan

Thats an interesting question.  When I worked for a glass contractor
we used methyl chloride however some of what I've used more recently
has been labeled methylene dichloride.  Looking at some of the data
sheets for acrylics it appears that either is a reasonable bonding
agent.  You might want to take a look at http://www.sdplastics.com/
which is San Diego Plastic's site.  They have some recommendations
there as well as some very strong usage warnings.  I agree that all
these products should be used in a well ventilated area and with extreme
caution.  Methyl Chloride was only handled in a syringe when we applied
it at the glass house.

Let me dig a little deeper and see if there are some safer methods.
