I suggest experiments with various mixtures of
Poly(2-ethyl-2-oxazoline) ("Aquazol, general chemical formula:
(C5H9NO)x ) in the three available molecular weights: Aquazol 500
molecular weight: 500,000, Aquazol 200 molecular weight: 200,000,
and Aquazol 50 molecular weight: 50,000. These are freely soluble in
water and are easily manipulated by heat in the solid, dry state
(Glass Temperature: 69 deg. C - 71 deg. C). Small amounts of other
organic solvents can be added to the aqueous solutions to increase
adhesion to non-polar surfaces.

The material is available from:

    Talas, New York

    Museum Services Corp, Minnesota

I am sorry but I am unaware of EU suppliers of these products.

The materials are manufactured by Polymer Chemistry Innovations,
Inc. <URL:http://www.polychemistry.com/products_aquazol.php> and
have been explored in the conservation literature:
