WORK IN PROGRESS – PRACTICAL EXPERIENCE IN THE CONSERVATION OF HIGH-GLOSS POLYESTER RESIN AND FLEXIBLE POLYVINYL CHLORIDE BASED ON EXEMPLARY CASES
BY SUSANNE GRANER
Two case studies are presented as an example of projects under- taken in the Conservation Department of Die Neue Sammlung – The International Design Museum Munich – concerning the conservation of modern materials. The first project features the conservation of a polyvinyl chloride coated fabric. The Throw Away sofa was designed by Willie Landels in the early 1960s. The structure of the sofa consists entirely of soft expanded polyurethane (PU) foam on a hard polystyrene base. The PU foam is covered with a polyvinyl chloride coated textile. The method of filling losses in the original material is described. The second project deals with losses in a coating of a high-gloss poly- ester resin and their filling. This varnish was applied to a “Home Entertainment Center” from around 1961/62 – the so called Kuba Komet – produced by Kuba Tonmöbel und Apparatebau in Wolfenbüttel, Germany. Different methods of compensating for losses in the degraded materials were tested and the imple- mented procedure is described. Both projects were assisted by students from Cologne and Paris.
