Does anyone have ideas for attaching faux vellum (not sheepskin)invitation to matboard? It seems as if they always slip when they are floated. The highest standard of preservation is not key here but I do want the piece to hold up for this generation. The customer said that gluing it was ok as they have others. I know that ATG Tape will eventually give way. Any ideas?

The first vellum piece I did like this buckled and I ruined it. I wasn't using very much paste either.

To the OP: Maybe you could use some of that 3m spray mount that everyone has been talking about or possibly find a way to sew the piece down inconspicuously.
 
True vellum and parchment are rawhide that was
dried under intense tension. Even with the best
hinging, they can not be expected to stay flat in
a frame, with no restraint from the mat.

Belinda,

The most important part of using wheat starch paste is TIME!

You must learn how long to wait from the time you paste a hinge until you actually apply the hinge to the art.

If you apply the hinge too soon, the art will probably pucker. If you wait too long you won't get a strong bond.

Once you have learned this skill you will understand why wheat starch paste is universally accepted as the best adhseive for hinging.

Check out the short how-to video on the FrameTek web pages.
 
IMHO Lascaux 360 and Japanese paper hinges are perfect for this kind of application. The cured Lascaux bonds well to the synthetic vellum without the risk of puckering, and is generally heat reversible. I say generally, because I have not used it with every kind of paper on the market, and it is chemically reversible regardless. I have not personally had any issue with reversibility specific to synthetic vellum.
 
Wally,

Have you ever actually reversed this adhesive? What is the chemical used to reverse it? What affect does this chemical have on papers or inks? Is it water reversable? Heat reversable - does it leave any residue on the paper?
 
Lascaux Acrylic Adhesives 360 HV and 498 HV are thermoplastic copolymer butyl-methacrylate dispersions thickened with acrylic butyl-ester. . They are all water-thinnable, but insoluble in water after drying. Once dry they are permanently soluble in acetone, toluene and xylene, but insoluble in White Spirit, VM & P Naphtha.

Lascaux Acrylic adhesive 360 hv is extremely elastic. The dry film remains permanently tacky, and can be used as a contact adhesive when doing hot-sealing linings.

Because these materials are copolymers, they can
be designed to be flexible and in the case of 360,
tacky without additives. The only draw back one
may find with 360 is its tackiness, which means
that it can release, eventually, in some applications, but in Wally's application, that
should not be a problem. The disadvantage, as
Greg point out, it would be harder to remove than
paste would be.

Greg, Yes, heat reversible at about 140 degrees F from synthetic vellum (low setting on hair dryer). Haven't had to do the chemical so don't rightly know what the side effects are. Technical info at Talasonline.com.
Attatchment done with simple burnishing, but moderate heat can be used (haven't had to). Long term studies have shown to be stable, non-donor product. 1000% elasticity (for what its worth). No residue.

Have been consulting with a couple of conservators about its use and doing experimental applications as time allows. I have used it primarily on synthetic substrates where traditional hinging methods won't work (20x24 Polaroid, Mylar, etc.), or on items particularly reactive to humidity changes.

I'm always looking for more info on the product if you have some, please share.
