Dibond Panels
After spending time with Sharon Knettell's thread on archival polyester supports I started doing a lot of research for my next project which is a 30x56 painting. Finally I decided what were going to be the decisive properties of this largish support.
1 - hydrophobic if at all possible (except for the paint surface)
2 - archival by which I mean it does not lose support strength or sag with time.
3 - good adhesion properties for acrylic paints (the medium I am forced to work with because of reactions to almost all oil paints)
4 - mold resistant
5 - light weight, but structurally strong
Thermal expansion properties were not a consideration as most paintings (except during shipping) reside in a pretty controlled temperature environment.
I finally settled on metal sided panels. Stainless steel by Reynobond was my first choice, but after second thoughts felt it violated criteria number 5.
Dibond panels finally rose to first choice, but the polyester surface on the aluminum poses a question concerning criteria 3. I wish to work directly on the panel's baked polyester surface. Since polyester canvas takes paint so well, what about a baked polyester surface?
What has been your experiences? Thanks
