Hi, I obtained a bottle of Dimethyldichlorosilane, a solution which is used to make glass repellent, mostly use in a lab setting. (see http://www.krackeler.com/products/fid/2725). I was wondering what I could do with it (besides using it in the lab), and it occured to me it might be usefull to make the glss in my 4*5 neg carrier repllent to finger print marks, perhaps dust, etc. I wonder though if there are possible adverse effects on the negative, Thanks, Best, Cor ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
