More Information
Summary:The present invention relates to a process for producing a composite material with reduced porosity by applying a vacuum to the mixing container before actual mixing steps. The composite material comprises a monomer mixture and a glass filler or a blend of glass fillers. The monomer mixture comprises at least one polymerizable monomer, a polymerization initiator and a polymerization stabilizer. Optionally, the composite material may comprise at least one pigment. The porosity of the composite material was determined and the porosity was compared with the porosity of the composite material produced by a process wherein a vacuum was not applied before all of the mixing steps. The preferred mixing container of the processes of the present invention is a planetary mixer or a centrifugal mixer. The composite material is for use in the dental industry.
