- Résumé
- "Commercial ready-made filler materials are widely used in the field of art conservation. Most ready-made filler materials are reactive to fluctuations of relative humidity. Dimensional changes in filler materials are an issue in conservation because damage can happen to the material surrounding the filled areas if the filler material expands or shrinks too much. In this research, the addition of glass microballoons (0.25g/cc, isostatic crush strength 750 psi) in a ready-made filling material, Flügger Acrylspartel, was investigated. The goal of this research is to determine if the addition of microballoons can decrease the dimensional changes from fluctuations of relative humidity, without affecting other mechanical properties of the filler material. The addition of microballoons in adhesives is known to improve reversibility and dimensional stability over time, to decrease tensile strength if higher concentrations are used, to decrease the density of overall material, to decrease its shrinkage properties during drying, to decrease flexibility, and to increase hardness. Various concentrations of glass microballoons were added to Flügger Acrylspartel. Flexibility and tensile strength were tested. In addition, handling and modeling properties, dimensional changes under high relative humidity (73%), and shrinkage upon drying were recorded. This research will determine if properties of ready-made filling materials can be modified easily in order to obtain a more stable material. Superior filler properties could be adapted for specific materials, such as rigid supports."
