Yupo paper

I found only two threads about this subject. Thought perhaps someone has more recently worked with this paper and could give me some advice.
I have four small acrylic paintings on yupo to frame. I wanted to float them on ragboard , leave about a 1/2 inch space around the art and float a double mat on 1/8 foamcore. But how do I mount them? The artist's info says the artwork is heat sensitive. Does she mean the paint or the paper? I guess I could mat them all around but they are very bright and fun but I think they would look so flat that way. Any ideas?

Yupo is not really paper ... it is plastic ... primarily polyproylene ... so heat would not be good!

the heat required to activate the beva is quite low, around 150-160º as I understand it. I was able to make the attachments with a tacking iron without any visible effect on the yupo. does the world really need yupo?

Actually we used to consider 150F-160F low temperature...but it is not longer considered so. There is a permanent low temperature HA board in Gilman MountCor that is truly low temp and safe at 130F. I have indeed tested Yupo in both mechanical and vacuum presses and it mounts beautifully...at 130F.

We need to begin thinking 130F for all digitals and previously heat sensitive items. I have tested it with brass rubbings, solid ink printing, higher melt 160F waxes, Tyvek, laser copies...and this is a revolutionary product. It is truly something we all need if heat mounting is to remain in our routine mounting methods.

I think your artist may have been referring to the paper, but it is the acrylic that could be the issue. If he/she has a scrap for you to test the acrylic you should do so. All this said...MountCor is permanent and only removable using solvents so an original being permanently mounted is more of the issue. In the future suggest you premount the Yupo paper to a selected substrate in preparation of later framing. That way you will not be unfavorably impacting original art; have come up with a good solution for your artist; are ready to float at a later date AND will have generated additional mount jobs.

When we are faced with plastic, rather than paper, we may be tempted to ignore traditional adhesives, but dextrin, modified starch, will adher to the back of an RC photo and it is worth a dry, with Yupo. The adhesive on most linen tapes is dextrin and you can transfer that onto Japanese tissue, with water and a brush, or with water and blotting, to form a hinge. As with all hinging, PRACTICE is required and this technique should not be used on the art, until it can be done with complete confidence, but it eliminates the need for heat and involves no plastic.

ok, scratch the outdated designation of 150º-160ºF as being low temperature. the yupo I was hinging was unaffected by heat sufficient to activate the beva adhesive. the attachment was successful. (and easily reversible)
