Could you help me immediately? As the conservator responsible, I am involved into an acid attack to a painting?
After two recent acid attacks on paintings, the Doerner Institut was asked by freelance restorers for an immediate assistance with conservation treatments. This has prompted the publication of updated instructions for neutralisation with ion-exchange resins. The strongly basic anion-exchange resin from the Lewatit product series (Bayer Leverkusen) was used at the end of the 1980s by the Doerner Institut to neutralise acid-damaged panels by Albrecht Dürer that had hung in the Alte Pinakothek. However, this ion-exchange resin is no longer commercially available. The search for an equivalent replacement resin led to a weakly basic ion-exchanger (Lewatit® MP 62, Lanxess Deutschland GmbH), which has the additional advantage of being much easier to prepare. Lanxess Deutschland generously provided the Doerner Institut with a large complimentary sample of Lewatit® MP 62. In an acute case, conservators from museums and collections requiring assistance are welcome to contact the Doerner Institut either by email or by phone. We will supply a corresponding amount of the ion-exchange resin and its safety data sheet along with instructions on the neutralisation of damaged artwork.
