[padg] RE: RE: RE: Re: RE: Re: Preservation photocopiers
I recently had an inquiry about using Krylon Preserve It! as a
"fixative" for digital photos and other printed matter.
(See
http://www.krylon.com/main/product_template.cfm?levelid=5&sub_levelid=8&;
productid=1732&content=product_details) I was pretty amazed when I
checked the MSDS and found it includes propane (14%), butane (13%),
toluene (18%) and acetone (38%). Yikes! And this stuff is being marketed
to scrapbookers.

How about the use of fixatives (spray-on, most likely, I mean) to seal
and thereby secure the adhesion? Any studies or anecdotal evidence that
fixatives are good or bad in the long run, or worth the extra trouble
(spraying, drying, etc.)?

Shannon is right, of course. There's two sides to the adhesion problem
and surface characteristics of the paper will also affect how well the
melted resin will bond to the paper.

Adhesion of photocopier (or laser printer) toner is influenced by
qualities of the paper as well as qualities of the machine or toner.
Toner just doesn't adhere well to some papers. When we prepare an
exhibit we've found we have to test the paper we want to use first. The
tape-pull test cited in another post is useful for this.
