Application of water-thinnable photopolymerizable resin for shaping of microreactors - Preliminary results

Abstract

The article presents the preliminary research on application of synthesized water-thinnable polyester resin for shaping of ceramic element by photopolymerization. The ceramic pastes made of alumina (30 vol%) and photocurable resins were used to prepare thin layers (tapes) and then were exposed to UV radiations. The cure depth and Konig hardness of cured layers were determined as well as the effect of a photoinitiator concentration on polymerization. The density of sintered ceramic samples also were examined. The research showed that the developed pastes with water-thinnable resin might be used to mold the ceramic elements by soft lithography method. The results obtained for polyester resin were compared with results obtained for commercially available photocurable resin.
