You can buy two kinds of adhesive for Corian on the "Corian for the
Creative" web site. One of the adhesives is the Dupont Seam Adhesive (the
same one that countertop installers use), and the other is an industrial
cyanoacrylate. You can also buy Corian and some kits on this site. They
offer a free 12-page booklet on how to work with Corian too. Go take a look
and be sure and follow the links to some really great Corian sculptures and
artwork too.
For tons of info on pen making and making Corian pens, go to the Penturners
Group on Yahoo. There is a huge amount of info in the group's Files
section, FAQ, and in the message archives - not to mention amongst the 1600
pen makers who are members!

Here's the Corian for the Creative site link:
