Paraloid B-72 is an ethyl methacrylate/methyl acrylate copolymer favoured by fine art and artifact conservators. There are many advantageous properties to this solvent that include its long term stability and its ability to stay clear, soluble and reversibility when adhered to an artwork or artifact. B-72 is soluble in acetone, toluene, xylene, and ethanol. The conservators at Art-Kitect use B-72 in instances when they need to consolidate instable pieces of the artwork; varnish an artwork; or use it as an adhesive.
Conservators also favour B-72 when conducting a restoration because of its reversible properties. In accordance to the Canadian Association for Professional Conservators (CAPC) Code of Ethics, “Ideally, the conservation professional shall use materials that can be most easily and most completely removed with minimal risk to any original part.”. B-72 is used as an ideal “barrier” between the original artwork and the additional artwork created by the restorer. If the restoration work proves to be inadequate in the future, it can easily be removed because of the barrier originally placed there.
B-72 solvent mixtures are toxic and should only be handled when wearing a carbon filter mask and in a room with exceptional ventilation (HEPA filter).
