Abstract
Masses based on synthetic resins are used by conservators to the fill losses of damaged enamel layer. It is the first stage of reconstruction of the damaged enamel layers, second is retouch of colour over the fill. To the conservation of glass and ceramics commonly epoxy resins are used. This type of resin provides a universal matrix for the preparation of polymer composites, because they can be modified in a wide range by addition of different fillers, in order to obtain masses, which are similar to the original enamel layer; in terms of texture, transparency, mechanical and physical properties.The aim of work was to verify the suitability of composites based on selected epoxy resins: Eurostac EP-IN 2501 hardener Eurostac Rapido K 2503 (Bresciani Srl, Milan) and Hxtal NYL-1 (Talas, New York), Templum Epo Top (CTS Srl, Altavilla Vicentina) Rompox R 1004 (Romex® MB GmbH, Euskirchen) with the addition of modified silica and the suspension polymerization of poly(methyl methacrylate) as masses to fill enamel losses.
