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 <URL:http://talasonline.com/> Museum Services Corp, Minnesota <URL:http://www.museumservicescorporation.com/scat/b.html> 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: Cameo, MFA Boston: <URL:http://cameo.mfa.org/materials/ record.asp?key=2170&subkey=682&Search=Search& MaterialName=Aquazol> **** Moderator's comments: The above URL has been wrapped for email.
